January 1, 796 S.C. / 487 I.C.: in the Astarte star system, a 20 000 spaceships Imperial fleet under Reinhard von Lohengramm's command is about to be cornered by three Alliance fleets of 13 000 spaceships each. Against the advice of his subordinates, Reinhard decides to strike first in order to defeat each fleet before they can join. The Allied commanders, trusting the overall odds of 2 to 1, don't anticipate this and rebuff Yang Wen-li's advice to quickly regroup their forces.

After the destruction of the 4th and 6th fleets, Reinhard's fleet engages the 2nd Fleet. When its commander is wounded, Yang takes command and manages to escape utter destruction. In Phezzan, Adrian Rubinsky, administrator of the planet, and Nikola Boltik, his main adviser, make comments on the battle and note that it won't change the strategic situation.

In Heinessen (capital planet of the Free Planets Alliance), a memorial for the soldiers who died at the battle of Astarte is held. The warmongering speech of Job Trüniht, the Secretary of Defence, is interrupted by Jessica Edwards, whose fiancé was killed in the battle: she asks him why the advocates of war always sacrifice the lives of others while hiding in safer places. While going home, she is attacked by members of the Patriotic Knights Corps (P.K.C.), a nationalistic organization secretly led by Trüniht. She is rescued by her friends Yang and Dusty Attenborough and barely escapes death. The next day, Yang is promoted to rear admiral in command of the newly formed 13th Fleet. His mission: to take the Iserlohn fortress, a powerful space station which has repelled every attack.

In Odin (capital planet of the Galactic Empire), Reinhard is promoted to imperial admiral after his victory at Astarte. With his friend Siegfried Kircheis, he pays a visit to his elder sister Annerose, the Emperor's favorite. In a flashback, Kircheis remember how he and Reinhard became friends, how Annerose was taken away from her home to be the Emperor's favorite and how they came to hate the high nobles and the Goldenbaum dynasty.

A new admiralty is created for Reinhard. He chooses commoners and lesser nobles to command his fleets: August Samuel Wahlen, Cornelius Lutz, Karl Gustav Kempf, Fritz Josef Bittenfeld, Ernest Mecklinger, Wolfgang Mittermeyer and Oskar von Reuenthal. Meanwhile, Maximilian von Kastrop has rebelled against the Empire. He thinks he is safe because of the "Artemis Necklace", a system of powerfully armed satellites built with the help of Phezzan. Reinhard sends a fleet under Kircheis' command to put an end to the rebellion. He manages to destroy the necklace. Kastrop is killed by his retainers and is the only casualty of the operation.

Yang decides to take Iserlohn by a ruse. The Rosen Ritter (Knights of the rose), a ground combat unit made of Imperial exiles, will pose as an imperial crew and infiltrate the fortress. Yang's staff is introduced: Murai, Patrichev, Fischer (a master of fleet maneuvers) and Frederica Greenhill, daughter of admiral Dwight Greenhill. The Iserlohn fleet is lured away from the fortress by decoys. When a damaged imperial spaceship asks for help, the commander of Iserlohn, who doesn't know where his fleet is due to radar jamming, authorizes it to dock...

May, 14, 796 S.C. / 487 I.C.: a fake imperial spaceship docks into Iserlohn. Walter von Schenkopp, commander of the Rosen Ritter, pretends to have important information and takes control of the center of command. The Iserlohn fleet comes back, only to be destroyed by the fortress' main weapon, the "Thor's Hammer". The fall of Iserlohn dramatically changes the strategic balance: Yang hopes it will lead to a peace treaty. Back in Heinessen, he wants to resign, but is promoted to vice-admiral instead.

Paul von Oberstein, chief of staff of the Iserlohn fleet, is in trouble. He saw through Yang's plan, but his commander didn't listen to him, and he fled before the destruction of the fleet. The three chiefs of the Imperial fleet resign, but want to make him responsible of the defeat. Oberstein meets Reinhard and explains how, like him, he hates the high nobles and the Goldenbaum dynasty, and offer his help. Reinhard agrees and obtains his pardon by advising the Emperor to refuse the chiefs' resignations.

Thirty years ago, marquis Klopstock was exiled form the imperial court. He asks prince Braunschweig, the Emperor's son-in-law, to ask forgiveness on his behalf. Braunschweig invites him to his daughter's birthday party. Klopstock's real goal is to bring a bomb in order to kill the Emperor, who will be there. At the party, Reinhard clashes with baron Flegel. The bomb is taken away by accident and makes little damage. Klopstock commits suicide and all the incident is kept secret.

Yang is sent to Thernussen (Heinessen's second largest city) with his ward, Julian Minci, to attend a ceremony at the Military Academy. He meets Jessica Edwards, who is campaigning for the Peace Party candidate in an upcoming election. We learn that Yang, while being loyal to democracy, has no love for the current politicians. The P.K.C. sets a bomb in the Peace Party's headquarters, killing the candidate, but their plan backfires when Jessica, who is the new Peace Party candidate, wins a landslide victory.

Susanna von Benemünde, a former favorite of the Emperor, wants to get rid of Annerose and win back the Emperor's love. She teams up with Flegel, who hopes that a scandal involving Annerose will lead to Reinhard's downfall. Annerose is abducted: she is to be killed and found with a supposed lover from the lower class. She is rescued by Kircheis, Reuenthal, Mittermeyer and Oberstein. Benemünde is forced to commit suicide. Flegel has been smart enough to leave no proof of his involvement, but Oberstein and Reinhard suspect him anyway.

In the Free Planets Alliance, the capture of Iserlohn has intoxicated the public, the military and the politicians. It is possible to invade the Empire from Iserlohn, and many people think it's time to conclude the crusade against tyranny. In the High Council, Joan Lebello (Secretary of Treasure) and Hwan Lewi (Secretary of Human Resources) think it's better to sign a peace treaty because the economy in on the verge of collapsing, but the Chairman explains that they will lose the next election unless they achieve a substantial military victory, so the High Council decides to invade the Empire; only Trüniht sides with Lebello and Lewi. The invasion plan is drafted by commodore Andrew Fork, an ambitious man so sure of the righteousness of the war that he discards any objections, especially those made by Yang, as siding with the enemy. The Free Planet Alliance will send a force of 8 fleets, 30 million men and 200 000 spaceships under the command of admiral Lazar Lobos, with admiral Greenhill as second-in-command. Meanwhile, in Phezzan, Rubinsky warns the Imperial High Commissioner that the Free Planets Alliance is planning a full scale invasion of the Empire.

August, 22, 796 S.C. /487 I.C.: the invasion of the Empire has begun. Reinhard implements a scorched earth strategy: all food is taken from the frontier zone, so the "Liberation force" of the Free Planets Alliance will be forced to feed the inhabitants. Reinhard plans to attack the invading fleets when their supply lines will be overstretched. Commodore Ulrich Kesler carries out the orders but, in the process, has to face someone from his past.

The Free Planets Alliance fleet has conquered more than 200 star systems (50 million inhabitants) without fighting. In Iserlohn, vice-admiral Alex Cazellnu drafts a supply plan, but he is worried about such a heavy burden: for him, Reinhard clearly wants the Free Planets Alliance to exhaust its resources on behalf of the liberated planets. The supply fleet is destroyed by Kircheis because Fork didn't think such an attack was possible. Yang, fearing a scorched earth policy, convinces his fellow fleet commanders to ask for a withdrawal. Riots break out on many planets because of the food shortage and the looting of the soldiers. Fork experiences a case of hysterical blindness in the face of his plan's failure. In Phezzan, Rubinsky grants a new loan to the Free Planets Alliance to maintain the balance: he hopes to economically control both the Empire and the Alliance. October, 10, 796 S.C. / 487 I.C.: Reinhard orders to launch the counterattack.

The Free Planets Alliance fleet are attacked: the 3rd, 7th and 12th fleets are destroyed and the 5th, 8th, 9th and 10th fleets are heavily damaged; only the 13th Fleet has managed to escape without taking too much damage. Admiral Lobos orders the fleets to regroup in the Amlitzer Starzone. Reinhard orders his admirals to regroup in the same area in order to destroy the remaining fleets. The Free Planets Alliance Fleet suffer further losses during the battle of Amlitzer Starzone (October, 15, 796 S.C. / 487 I.C.).

End of the battle of Amlitzer: Yang's 13th Fleet keeps the Imperial Fleet at bay, allowing admiral Bucock to withdraw the remaining fleets. After that, Yang manages to escape destruction (once again). Meanwhile, the Emperor dies without appointing an heir. Reinhard teams up with premier Lichtenlade in order to crown Erwin Josef II, one of the late emperor's three grandchildren. Prince Braunschweig and marquis Littenheim, fathers of the two others, prepare to seek revenge. Back in the Free Planets Alliance, Trüniht is appointed temporary chairman of the High Council, Bucock commander-in-chief of the Fleet, and Yang commander of Iserlohn. he takes all his staff with him, plus Attenborough and a new officer, Julian Minci, and hopes to have Alex Cazellnu appointed as commissioner of the fortress. Meanwhile, in Phezzan, Rubinsky takes his orders from the Grand Bishop of the Earth Cult.

Julian Minci asks Frederica Greenhill how Yang became the "Hero of El Facil": 9 years ago. The Free Planets Alliance fleet, led by Arthur Lynch, fled the approaching Imperial Fleet, leaving 3 million people behind; Yang, one of the few officers left, organized the evacuation while the Alliance Fleet was defeated. Meanwhile, in the Empire, Reinhard thinks a civil war is about to break out; in order to avoid an intervention form the Alliance, he decides to infiltrate Lynch in the Alliance to stage a military coup. The move is hidden behind an exchange of 2 million prisoners of war. End of 796 S.C. / 487 I.C.

Prince Brauschweig and marquis Littenheim team up to overthrow the young Emperor and get rid of Reinhard. Count Franz von Mariendorf wants to join the conspiracy, but his daughter, Hildegard persuade him not to do so because a new order is rising under Reinhard. She goes to Reinhard and offer her family's allegiance. The high nobles create the Lippstadt League, led by Braunschweig and Littenheim; admiral von Merkatz agrees (although reluctantly) to command their military forces. April, 6, 797 S.C. / 488 I.C.: Reinhard strikes first and manages to arrest many conspirators, but Brauschweig and Littenheim flee and regroup most of their forces in the Geiesburg Fortress.

Andrew Fork is released from the Hospital. Fork attempts to assassinate HQ chief Kubersly. Reinhard decides to lead the main fleet against Geiesburg while Kircheis, helped by vice-admirals Lutz and Wahlen, will take control of the other areas. Meanwhile, in the Free Planets Alliance, a military uprising begins (April 3, 797 S.C. / 488 I.C.). In Heinessen, a military coup overthrows the High Council (April, 13): the National Salvation Military Council, led by admiral Greenhill, suspends the democratic institutions. Trüniht goes into hiding. Yang decide to fight for democracy : the 13th Fleets leaves Iserlohn (April, 20) while the 11th Fleet goes out to stop it.

The Lippstadt League plans to draw Reinhard to Geiesburg in order to defeat him in a decisive battle. As a part of this plan, admiral Staaden has to lead a fleet to Odin in order to cut Reinhard's fleet from its base. Mittermeyer is sent to intercept Staaden, whose fleet is crushed during the battle of Altener and withdraws to the Rentenberg fortress. Reinhard decides to take the fortress, but the boarding parties are repelled by the garrison, led by admiral Ovlesser. An assault led by Mittermeyer and Reuenthal succeeds, and Ovlesser is taken prisoner. Reinhard wants to execute him, but Oberstein advises to send him back to Geiesburg. Ovlesser is released, but is executed by Braunschweig who thinks he was freed because he turned against him. Fear of treason spreads among the Lippstadt League.

Schenkopp takes control of the rebel planets on behalf of the Yang fleet. The National Salvation Military Council sends commodore Bagdashu to Yang to pose as a traitor to the coup in order to kill him, but Schenkopp manages to take him away. Yang's 13th Fleet meets the 11th Fleet in the Doria star system; the 11th Fleet is destroyed because its commanders turn down Yang's proposal of surrender. After the battle, Bagdashu decides to join Yang because his victory is certain. Meanwhile, in Heinessen, a peaceful gathering against the coup is held in a stadium. When the army tries to scatter it, it turns into a riot, and thousands are killed, including Jessica Edwards.

Littenheim leaves Geiesburg with his fleet to recover the territories conquered by Kircheis. Because of its lack of discipline and overconfidence of its commanders, the Littenheim Fleet is defeated; while running away, Littenheim's spaceship opens fire on allies who are in the way. In the Garmisch fortress, Littenheim is killed by his men, enraged by such an attitude. Meanwhile, Reinhard's fleet arrives in the area of Geiesburg. The Lippstadt Fleet attacks him but is utterly beaten and barely avoids complete destruction thanks to admiral Merkatz.

And uprising takes place in Westerland, one of Braunschweig's territories. He decides to kill all the inhabitants by a nuclear strike. Reinhard hears about the plan and wants to send a fleet to stop it, but Oberstein thinks it's better to let it happen, record it and use this monstruous act as a propaganda tool against the high nobles. Reinhard is against it, but Oberstein's plan succeeds because he lied about the time of the strike. The images are nevertheless broadcasted in all the Empire: Reinhard becomes the hero of the commoners and, even in Geiesburg, many think its time to get rid of the high nobles. The Lippstadt Fleet makes a last sortie, but is defeated; baron Flegel is killed by his men when he wants to make a suicide attack, and his crew flees to Phezzan. Merkatz, too proud to surrender, decides to kill himself, but Bernhard von Schneider advises him to take refuge in Iserlohn. Braunschweig is forced to commit suicide by Ansbach, his chief retained, who promises to avenge him. September 797 S.C. / 488 I.C.: fall of the Geiesburg fortress and end of the Lippstadt League.

After Yang's victory, the National Salvation Military Council loses its supporters and only controls Heinessen, well protected by the Artemis Necklace. Yang decides to use propaganda and asks Bagdashu to publicly admit that the Empire is behind the coup. Bagdashu's speech is widely broadcasted in Heinessen. The leaders of the coup are astonished, but Lynch, who helped them, says that's the truth. Meanwhile, Yang manages to destroy the Artemis Necklace. Hopeless, the leaders of the National Salvation Military Council decide to surrender, but to destroy all evidence of the Empire's involvement. Admiral Greenill and Lynch are killed in the ensuing gunfight. Democracy is restored. Trüniht, hidden by members of the Earth Cult, comes back to power.

Kircheis arrives at Geiesburg. He has an argument with Reinhard about the handling of the Westerland events. Reinhard assumes full responsibility for Oberstein's actions. A message is sent from Odin: Lichtenlade is plotting to get rid of Reinhard. Reinhard receives some rebel commanders. Adalbert von Fahrenheit joins Reinhard's team. Ansbach comes in with Braunschweig's coffin, but takes out a weapon and aims at Reinhard...

Ansbach misses; Oberstein protects Reinhard with his body while Kircheis grabs the weapons, but is killed in the process. Reinhard is devastated by his friend's death and is unable to make any decisions for several days. His admirals go back to Odin, arrest Lichtenlade for the murder attempt on Reinhard. Reinhard finally recovers and speaks to Annerose, who decides to retire to a small cottage; Reinhard feels left alone. Meanwhile, in Phezzan, Rubinsky decides to change his strategy, since the balance of power cannot be maintained: Phezzan will support the Empire. He sends Boltik as Phezzan's ambassador to Odin and replaces him with Rupert Kesselring.

January 1, 798 S.C. / 489 I.C.: Reinhard von Lohengramm is now Premier and Commander-in-chief of the imperial military. He implements many reforms for the welfare of the people. Meanwhile, an training sortie, under Dusty Attenborough's command, turns out to be Julian Minci's first battle as a fighter pilot. The Attenborough Fleet is on the verge to be crushed, but Yang Wen-li, with the help of Admiral Merkatz, goes out of Iserlohn with the whole fleet and saves the day (January, 16).

January, 798 S.C. / 489 I.C.: Admiral von Schaft, head of the Science and Technology Division, works out a plan to take Iserlohn back. The Geiesburg fortress is to become a mobile fortress by adding warp engines: its firepower is a match to Iserlohn's, so the Imperial fleet will be able to defeat the Iserlohn Fleet. The operation will be under Admiral Kempf's command, with Admiral Müller as second-in-command. In Phezzan, Rubinsky decides to support the plan and asks Kesselring to find a way to move Yang away from Iserlohn. Some of Mittermeyer and Reuenthal's background is revealed.

In Phezzan, Rubinsky explains his plans to a bishop of the Earth Cult. He will use his contacts in the Free Planets Alliance, such as chairman Trüniht, to make the Alliance crumble from inside, paving the way for an Imperial victory. Then, Reinhard is to be murdered. Kesselring is sent to the Alliance's commissioner in Phezzan, saying the financial support can continue only if the Alliance is a stable democracy, hinting that Yang is willing to seize power. In Iserlohn, Alex Cazellnu is concerned about Yang's safety: for the time being, his skills are needed, but he fears that Trüniht wants to dispose of him in the end. In Heinessen, Trüniht, who dislikes Yang's popularity, asks the Secretary of Defence, Negreponte, to form an inquiry committee about Yang's action during the coup.

Yang is summoned to Heinessen, where the Secretary of Defence is holding an inquiry. This move shocks his staff because such a committee has no legal basis. In Phezzan, Kesselring enlists two former members of the Lippstadt League, Leopold Schumacher and Alfred von Landsberg to carry out a plan we know nothing about. March 13, 798 S.C. / 489 I.C.: the test of the warp drive of the Geiesburg fortress is a success. The fortress and its supporting fleet can now move to the Iserlohn Corridor and attack the Alliance's fortress.

On his way to Heinessen, Yang thinks about the current situation. The Alliance's disrespect for human rights, democracy and freedom on the pretense of the war is leading the nation toward its destruction; moreover, the failed invasion of the Empire and the civil war have drastically weakened the Alliance's military. In Heinessen, Yang is separated from his companions, Louis Mashengo and Frederica Greenhill. While Yang's personality and actions are questionned by the committee, Greenhill and Mashengo try to reach him, but any contact is denied. They go to Admiral Bucock for help, but are attacked by the P.K.C. (which appears to be related to the Earth Cult) and rescued by Bucock's staff. April 10, 798 S.C. / 489 I.C.: the Geiesburg Fortress enters the Iserlohn Corridor.

While the inquiry continues, Greenhill tries to find out where is Yang and discovers that the government controls the media and leaves little room for the opposition: the Free Planets Alliance is a democracy in name only. When the news of a new imperial attack reaches Heinessen, the inquiry is suspended and Yang sent back to Iserlohn. However, the journey will take at least four weeks: Yang's staff thinks about a strategy to hold on and not let the enemy know that Yang is not there.

Geiesburg and Iserlohn fire at each other, causing little damage to the fortresses. After that, Schenkopp and the Rosen Ritter repel a boarding party. Kempf then decide to use the firepower of Geiesburg and the Müller Fleet to make a breach in Iserlohn's outer wall. The operation succeeds, but the Imperial forces can't get through because Admiral Merkatz launches the Iserlohn Fleet and drive off the Müller Fleet. Meanwhile, Yang is on his way back with some reinforcement. April, 15, 798 S.C. / 489 I.C.: in spite of the numerical advantage of the Imperial fleet, the situation is deadlocked. However, Müller learns from a dying prisoner of war that Yang is not in Iserlohn.

Reinhard is displeased by Kempf's report and decides to dispatch Mittermeyer end Reuenthal Fleet; he thinks the best tacticts was to smash Geiesburg against Iserlohn and destroy both fortresses (Yang has the same idea). Imperial scout ships detect Yang's reinforcement fleet. Kempf plans to lure the Iserlohn Fleet out of the fortress by pretending to retreat, then strike and seal it in the fortress, which will allow him to attack the reinforcements. Julian Minci sees through his plan. Merkatz, leading the Iserlohn fleet, pretends to fall into the trap, thus the Imperial Fleet is attacked from behind when it engages Yang's fleet. Kempf finally decides to smash Geiesburg into Iserlohn, but the Alliance's fleet destroys the engines, and the damaged the fortress moves randomly, destroying many imperial ships, before blowing up. The Imperial Fleet falls back but, against Yang's order, some commanders decide to pursue the Imperial Fleet.

The Mittermeyer and Reuenthal Fleets meet the retreating Imperial fleet and destroy the Alliance's pursuing ships before falling back when the Iserlohn Fleet shows up. In Odin, Müller is forgiven by Reinhard. Reinhard tells Hildegard von Mariendorf that power should not be inherited, but seized. In Phezzan, Kesselring explains to Rubinsky that the Free Planets Alliance is on the verge of bankruptcy; they decide to go on with their plan. It is revealed that Kesselring is Rubinsky's illegitimate son. Back in Iserlohn, Yang shares with Julian Minci his thoughts about military strength and how it is often used against the citizen it was supposed to protect.

Admiral Kessler, chief of the Military Police, informs Reinhard that two former members of the Lippstadt League (Landsberg and Schumacher) have arrived in Odin, and may be involved in some plot. Reinhard asks Hildegard for her advice: shes thinks they are in fact sent by Phezzan and will try to abduct someone, probably the young Emperor. later, she pays a visit to Annerose von Grünewald (Reinhard's elder sister) and persuades her to let Reinhard increase the security measures. Reinhard summons Boltik, the Commissioner of Phezzan, tells him he knows everything about their plan, and asks what is Phezzan's interest: Boltik answers that Phezzan expects to control the space communications and trade in an unified Empire. Reinhard agrees to act according to Rubinsky's plan, only if Phezzan grants a free passage through the Phezzan Corridor to the Imperial Fleet.

July 6-7, 798 S.C. / 489 I.C.: Landsberg and Schumacher kidnap the young Emperor under hidden underground tunnels within the palace grounds. Admiral Molt commits suicide over his failure to guard the grounds and product the Emperor. Hildegard sees through the kidnapping and confronts Reinhard over why he allowed the kidnapping to take place. Reinhard explains he cautiously joined with Phezzan as a method of justification for the Empire to invade the Alliance.

The young Emperor passes through Phezzan into Alliance territory. The Alliance government declares that they will shelter the refugees while the nobles announce a government in exile. Merkatz is appointed as secretary of defense without his own consent. August, 20, 798 S.C. / 489 I.C.: Reinhard declares the government in exile kidnapped the young Emperor in an underhanded act of cowardice. The public within the Empire mobilizes in support of Reinhard's declaration of total war.

Julian is assigned to Phezzan by central command. Yang and his staff decide to assign Mashengo to be Julian's body guard. Yang shares with Julian his thoughts about the possibility of Phezzan allying with the Empire due to the power balance being shifted. Julian mentions the possibility of Phezzan allying with the Empire not because of realist means, but instead out of ideological or religious reasons. Julian agrees to be of use to Yang and go to Phezzan to spy on any developments. The Iserlohn staff say their goodbyes to Julian.

As Julian travels to Heinessen to accept his commission in Phezzan; he thinks about how Yang's background in history. Julian reviews the history of humanity during this long trip. The history lesson starts with the birth of the Galactic Republic in 2801 and man's continued expansion into space. The lesson then touches on space piracy, the increase in military powers, and the eventual decadence which let to the rise of the Galactic Empire. The final parts of the lesson include the creation of the Alliance up to the first military conflict between the Alliance and Empire.

Admiral Bucock informs Julian that the alliance government is trying to divide Yang from his allies as a way of preventing any future powergrab by Yang. Reinhard discusses his plans on using the Phezzan corridor with his Admirals, calling the plan Operation Ragnarok. Over 1 million ships are planned to be in the fleet. Reinhart speaks with Oberstein and discuss the use and eventually the expendability of Boltik, current Commissioner of Phezzan. Oberstein creates a secret police with Lang as the leader. September 20, 798 S.C. / 489 I.C.: 8 month old Catherine succeeds the throne of the Empire as the new Empress.

Julian arrives on Phezzan. The next evening, he attends his welcome party. Julian spreads conjecture about a possible invasion of Phezzan from the Empire. Reinhart organizes his fleet for operation Ragnarok. Admiral Bucock tries to warn the Alliance National Defense Council about a possible Phezzan corridor attack, but is ignored. November, 20, 798 S.C. / 489 I.C.: Admiral Reuenthal leading an Imperial Fleet of 36,000 ships lays siege to Iserlohn. Carrying out the first part of Operation Ragnarok.

Reuenthal plans a war of attrition against Iserlohn. Reuenthal sees the Hyperion, Yang's flagship, emerge from port and decides to rush his fleet to destroy the Hyperion. However this is a feint and the Rosen Ritter led by Schenkopp latch on to Reuenthal's flagship and engage in combat. The battle is a draw and Schenkopp eventually withdraws. Reuenthal returns to his plan of attrition by rotating his attack forces in small groups. December 9, 798 S.C. / 489 I.C.: Part two of Operation Ragnarok launches from the Empire homeworld.

The Imperial fleet under Mittermeyer invades Phezzan after feigning to approach Iserlohn. Kesselring tries to kill Rubinsky, but Rubinsky had a trap laid out and kills Kesselring instead. Rubinsky goes into hiding. Julian and Mashengo destroy the computers in the Alliance High commissioner's office. Julian later finds a smuggler to take him, Mashengo, and the cowardly Alliance commissioner out of Phezzan space. Mittermeyer orders the execution of soldiers which raped and robbed civilians. The Empire secures Alliance space maps from the Phezzan Navigation Office.

Reinhard celebrates the new year with his officers. The citizens on Heinessen panic and question the government's handling of the situation. Admiral Bucock is chosen to lead the defense of the Alliance. The Alliance situation is dire as the fleets are greatly weakened from past campaigns, the only intact fleet is the 1st fleet. The 14th and 15th fleet are then created from a hodgepodge of 20,000 ships from around the Alliance. The military leaders of the Alliance realize however, they do not have enough ships to block the exit of the Phezzan corridor. Yang is given free rein over any future actions for the 13th fleet. January 8, 799 S.C. / 490 I.C.: The first Imperial fleet, led by Mittermeyer passes through the Phezzan corridor into Alliance territory.

On Iserlohn Yang decides to abandon the fortress. Yang realizes that the fortress no longer has strategic value as a choke point defense after the Imperial fleet has broken through Phezzan space. Furthermore, the Fortress would be able to hold out till the end of the war, but would probably be forced back into Empire territory in the event of a peace treaty. Yang's fleet prepares bombs and another surprise on Iserlohn and abandons the fortress of all staff and civilians. January 9, 799 S.C. / 490 Reuenthal has retaken Iserlohn fortess.

Julian and friends leave Phezzan on a cargo ship. Julian tricks the captain of an Imperial destroyer and captures the destroyer. Reinhard organizes and briefs his fleet on the invasion plan. The Imperial fleet has a 3 to 1 fleet number advantage over the hodgepodge fleet of the Alliance. The Imperial and Alliance fleets are days away from a battle in the uninhabited Rantemario star system.

The Imperial fleet takes a snake formation as they approach the Rantemario system. Bucock fleet is forced to attack the center of the snake formation as their only plausible tactical response. The Alliance fleet is badly damaged as the much larger Imperial fleet closes in on all sides. Bocock tries to minimize losses to the Alliance fleet by using a space current to slow down the Empire's advance and disabling enemy engines with fighters. At the last moment Yang's fleet approaches from behind, stopping the total destruction of the Alliance fleet under Bucock. The Imperial fleet reorganizes their fleet and heads for next Alliance system. Julian's destroyer joins up with the Alliance fleet at Heinessen.

Yang is promoted to Fleet Admiral as he lands on Heinessen. Yang clarifies his war plan to the government of the Alliance. The war plan is to attack the spread out Imperial fleet and lure out Reinhard. If Reinhard is killed, his admirals will lose their unifying force, potentially causing infighting. Julian and Yang go out to dinner and catch up on the events which have happened in the last few months. Merkatz leads the exile Imperial government fleet to join with Yang's. Reinhard has a flu and thinks of the past. The end of February, 799 S.C. / 490 I.C.: The unified Alliance fleet launches from Heinessen.

Yang attacks the supply lines of the Imperial fleet successfully. Next, Yang defeats a fleet near a black hole. Reinhard's anger at these losses are reaching boiling point. Mittermeyer and Reuenthal realize that they will have to launch a large offensive versus Yang if they hope to win before morale and food drops to dangerous levels. Yang defeats another fleet by filling supply pods with helium, then igniting the pods when the Imperial fleet nears them for pick up. Yang's guerrilla warfare tactics leave the Imperial fleet with uncertainty on where Yang will appear next. An attack on Heinessen is vetoed by both the Imperial Admirals and Reinhard. The only remaining option is a full fleet encounter by using Reinhard as bait.

Yang announces R&R time before the final battle. Julian and Yang discuss the differing battle goals for both sides. The Alliance needs to kill Reinhard while the Empire needs to hold out long enough for reinforcements to trap the Alliance. Yang finally reciprocates Frederica's feelings and proposes marriage after the war is over. Frederica is thrilled at the idea. It is revealed that Yang felt a large amount of guilt at pursuing familial happiness with all the deaths he has caused. Both fleets engage each other cautiously; both sides suspect traps or tricks from the other.

Yang organizes his fleet for a blitzkrieg directly at Reinhard's flagship, the Brunhilde. Reinhard divides his fleet into multiple layers of ships, providing an rotation for each broken layer. Ivan Konev is killed in battle when his strike craft is lured into cruiser fire. Yang realizes that it has become an issue of endurance if Reinhard's fleet is continuously reforming the front line. The Alliance fleet tricks Reinhard's front line into entering an asteroid field. Reinhard is divided from his main force as that group is surrounded by Yang's fleet. Müller's fleet is the first to return, rescuing the Brunhilde and acting as a shield.

Yang's fleet nears firing range of the Brunhilde, but a message from Heinessen declares a ceasefire. During the battle of Vermillion, Hildegard had convinced Mittermeyer fleet to take Heinessen. Hildegard is wary of Reuenthal's ambitions, but has Mittermeyer convince Reuenthal to join the Heinessen attack. In Hildegard's judgement, the battle of Vermillion would have concluded in Reinhard's death before the other fleets could return in time. Trüniht plans to surrender, while the other members of the Alliance government would prefer to fight and die. During the meeting, armed Earth Cult members rescue Trüniht. The surrender of the Alliance has divided Yang's staff, some preferring to ignore orders and kill Reinhard while others grudgingly accept the ceasefire. It is decided that a portion of Yang's staff will escape with Admiral Merkatz to a life of piracy.

Yang boards the Brunhilde and meets with Reinhard. Yang declines an offer by Reinhard to the position of Imperial Fleet Admiral, instead preferring to retire to a quiet life. Reinhard and Yang discuss government and philosophy. The treaty of Barlat is announced, formally ending hostilities. The concessions within the treaty increase civil unrest, public anger turns from the Empire to former Chairman Trüniht. Admiral Lennenkanpt is appointed Imperial consul of Heinessen.

The Merkatz fleet is only 60 ships, but they plan to procure more from raids and decommissioned Alliance ships. Julian meets Katerose von Kreutzer for the first time. Poplan joins Julian's group to Earth. Till the fleet is needed once again, Merkatz plans to maintain and safeguard it.

On the long trip to Earth, Julian and Poplan review the history of Earth. The lesson starts with the 13 Day War between Earth factions in 2039 AD. After the nuclear exchange, the unification of all governments on Earth occurs in 2129 AD. Following unification man expands into the stars. However, the lack autonomy to colonies, unequal economic polities, and tyranny from the Earth government culminate in multiple conflicts and human rights violations. The end of these chaotic conflicts eventually leads to the creation of the Galactic Republic in 2801 and Earth being forgotten.

Emperor Reinhard announces his new cabinet. Through a personal favor to Hildegard's father, the new secretary of state, Reinhard agrees to visit Künmel. During the lunch, it is revealed that Künmel and the Earth cult had placed explosives under the court. Trüniht leaks information to the chief of ministry police Kesler; an assassination attempt is planned on Reinhard. The Earth cultists around Odin are attacked in full force by the military police. Reinhard disables the trigger, via Künmel complacency. The Mariendorfs are put under house arrest. July 10, 799 S.C. / 1 N.I.C.: Julian crew arrives on Earth, that same day the Empire decides to suppress Earth by force.

Oberstein confronts Reinhard to choose a consort for bearing a heir. Reinhard releases Hildegard and her father from house arrest. Reuenthal reveals to Mittermeyer that his personal demons are effecting his lifestyle. At this time Reuenthal also gives up his ambition for power, realizing he can not exceed Reinhard. Müller launches his fleet from Odin towards Earth. Julian, Mashengo, and Poplan arrive on Earth and head to the Earth Cult holy temple.

On Odin, Reinhard reviews the secret history of the past Emperors of the Empire. On Heinessen Yang is enjoying his private life.

During this period, both women realized they can trade information inside the food.

July 17, 799 S.C. / 1 N.I.C.: Alliance forces in accordance with the Treaty of Barlat start decommissioning and disassembling Alliance cruisers and carriers. The Merkatz freedom fighter fleet launches a sneak attack on the Imperial flagship, causing many planned decommissioned soldiers and ships to switch sides. Oberstein tricks Lennenkanpt into blaming Yang. Yang is arrested in his home by Alliance soldiers. All of Yang's subordinates notice increased surveillance as a sign of danger. If Yang is executed by the Empire, it would cause a popular uprising in the Alliance. The uprising would thus give the Empire a reason to subjugate the Alliance further. The Alliance government thus considers executing Yang before the Empire, to avoid interference or subjugation

Prime Minister Lebello visits Yang in prison. Yang realizes he will be used as a scapegoat by the Alliance to avoid Imperial intervention. Schenkopp and Attenborough reorganize Yang's subordinates. With the Rosen Ritter in full rebellion, the Alliance troops are no match for the difference in battle experience and morale. During the chaos, the Rosen Ritter kidnaps the Prime Minister. However, the Alliance military decides to sacrifice the PM and execute Yang early. Frederica and Schenkopp save Yang at the last moment, escaping with Yang's staff into the night.

Fredrica applies make up to Lennenkanpt's corpse, tricking the Imperials. Cazellnu resigns his post in the Alliance government and joins Yang's fleet with his family.

The Wahlen Imperial fleet arrives near Earth orbit. An Earth Cultist within Wahlen's flagship attacks Wahlen with a poisoned blade. Wahlen's arm is amputated and he goes into a coma. Meanwhile, Julian and Poplan realize the food being served to cultists has minute amounts of Thyoxin, a mind control poison. Julian goes through withdrawal symptoms, and meets up with the others in the infirmary. Wahlen awakens from his coma and orders a ground assault and missile bombardments of the Terraism fortress. The Imperial forces and Julian's friends (Posing as Phezzan infiltrators.) work together against the Earth Cultists. Julian and the others escape with the Terraism data while the cultists detonate the Earth cult fortress.

Julian convinces Wahlan to escort him to Odin. The Imperial admirals discuss the issue of Lennenkanpt's capture and the unverified accusations against Yang. Oberstein argues that the subterfuge within Heinessen could be very advantageous to the Empire. The Admirals all reject Oberstein's conclusion and opportunism, preferring to investigate the plot for the truth. Yang's fleet heads towards Merkatz's base. During this trip, Yang considers the miscalculations leading up to his capture as well as the next steps needed. Reinhard formalizes his plan of moving the Imperial capital to Phezzan. August 13, 799 S.C. / 1 N.I.C.: Planet El Facil declares independence from the Empire and Alliance.

Rumors spread around the Alliance on the whereabouts of Yang and Lennenkanpt. El Facil, the only independent planet not under Imperial supervision, aggressively tries to recruit Yang. Yang decides to remain on the sidelines. The reasoning behind's Yang's caution is due to the Yang fleet not having enough military power to protect El Facil or any other systems. Yang decides his next action depends heavily on the Empire's next move. On Heinessen, Lebello considers the possibility of Yang allying with the Empire for revenge as well as asking Yang to return and lead the Alliance. Reinhard receives a report on the truth behind Yang's movements and Lennenkanpt's actions. Reinhard summons his three top Imperial Military commanders...

Reinhard considers the possibility of Yang joining the Empire. Hildegard considers the different power groups at play. The current balance of power is divided between the Empire, the Alliance, Yang, El Facil, Phezzan merchants, Earth Cultists, and Goldenbaum loyalists. Yang is seen as a possible unifier of the Alliance, El Facil, and Phezzan merchants. Meanwhile Silverberche, the Imperial Secretary of Industry starts construction of the new Imperial capital in Phezzan. During a high level staff meeting, Reinhard decides that the Galactic unification of humanity is vital.

Reinhard announces the situation to all citizens within the galaxy. Reinhard covers the failure of Lennenkanpt and the selling out of Yang and Lennenkanpt by the Alliance government. He further declares Treaty of Barlat's spirit has been desecrated with the only solution being force. Yang realizes that he has been cut off from allying himself with the Alliance government. Bucock returns from retirement. The next day, Reinhard announces the fleet organization for the second Ragnarok operation. Alliance diplomat Odets desperately heads into Imperial territory to ask for a ceasefire.

On Odin, Julian and friends prepare to leave the planet. Alliance Chief of Staff Trung Yu Chan prepares to send Yang supplies, ships, and personnel. Around the Alliance, the military is sending Yang all of their extra personal, ships, and supplies. Yang consults with his staff, considering asking Phezzan merchants for war funding. Yang's fleet finally decides to go to El Facil. The government on El Facil plans to declare a new legitimate democratic government.

The Imperial forces head deeper into Alliance territory. Julian and friends arrive on El Facil. Julian passes off the Terraism data disk to Yang. Yang and stuff discuss the next step, namely the retaking of Iserlohn Fortress. The El Facil government is wary of Yang being outside of their field of control, thus they refuse to let Yang lead the next operation. Effectively Yang has become a bargaining ship for controlling the excesses of his subordinates. Yang speaks with Konev about the possibility of Phezzan's aid. December, 799 S.C. / 1 N.I.C.: The El Facil fleet, under Merkatz launches for Iserlohn. During the same time, the last of the Alliance fleet launches for their final sortie.

All military campaigns for both the Alliance and Empire are put on hold to celebrate the new year. Admiral Lutz starts receiving multiple conflicting launch and Iserlohn defense orders. Reinhard is furious at Lutz's refusal to launch. Lutz finally launches with all his forces, hoping to sandwich the El Facil fleet between him and Thor's Hammer. The Rosen Ritter disable the Thor's Hammer with a previously encoded computer lock down code. The enemy infantry forces are superior in numbers, but not in skill or morale. The Rossen Ritter eventually enter a backup control room and fire the Hammer at Lutz's returning fleet. January 14th, 800 S.C. / 2 N.I.C.: Iserlohn is once again under Yang's control.

The Imperial fleet decides to accept Bucock's challenge head on and sends most their ships to meet in the Mar-Adetta system. The Mar-Adetta has unstable solar activity, communication jamming and a corridor through an asteroid belt. The Bucock fleet hides in the large corridor. As the Imperial fleets charge in, they are greeted by unstable asteroids, artillery ship fire, and space mines. The Alliance fleet is astute and attacks from unexpected areas within and behind the belt. January 16th, 800 S.C. / 2 N.I.C.: The Imperial fleet is in the middle of an unexpectedly difficult battle.

Bucock's fleet advances through the Müller fleet while being pursued and surrounded by many others. Bucock's Alliance fleet is unable to charge and kill Rienhard. Hilde advises Reinhard to offer surrender to Bucock. Instead of accepting defeat, the Alliance officers toast to friendship and democracy. Afterwards, the Imperial fleet decimates all remaining Alliance ships. The Imperial victory celebration is cut short when news of Lutz's defeat at Iserlohn is received. The situation has changed for the Imperials if the plan was coordinated. The Imperial fleet would have cut off supply lines if Phezzan fell as well. With that possibility, Reinhard could have underestimated the importance of Iserlohn. Countering the panic, Hilde points out Yang would not have sacrificed his allies for a stall. The Imperial forces thus resumes their course for Heinessen.

The news of Fleet Admiral Bucock's death reaches Iserlohn. The Yang declares a mourning period for Bucock. Lebello is assassinated by his subordinates. The Alliance government surrenders unconditionally. On February 9th, Reinhard lands on Heinessen. The Imperial soldiers discover low level bureaucrats unwilling to surrender public documents, records, or property to the Empire. Reinhard commends on how the Alliance perished precisely because such remarkable government servants were kept below positions of governance. Reinhard disgusted over treachery, then declares death upon Lebello's killers. February 20th, 800 S.C. / 2 N.I.C.: The 273 history of the Free Planets Alliance ended.

Reinhard considers when and how to take El Facil and Iserlohn. Yang considers the position of his forces. Katerose von Kreutzer confronts her illegitimate father, General Schenkopp. The Iserlohn reviews the Terraism data disk, discovering troublesome information: Phezzan and the Earth Cult have been working together for over a century. Yang, Frederica, and Julian talk about the role of military within government as well as Reinhard's next step. In a secret location, Rubinsky discusses his influence and agents. Meanwhile, within Reinhard's office, a letter arrives which postpones the expedition to Iserlohn...

Reuenthal is arrested by the Imperial police under suspicion of overthrowing Reinhard. It is revealed that Lang, the head of the secret police initialed the investigation. Reuenthal is accused of harboring a woman of the exiled Lichtenlade family. Oberstein is suspicious of Lang's intentions. It is revealed that the woman is pregnant with Reuenthal's child.

Yang and Julian discuss their situation, talking till sunrise. The Earth Cult convinces Fork to try to assassinate Yang. Iserlohn responds to Bittenfeld, planning to provoke him to attack prematurely before the main Imperial fleets arrive.

Bittenfeld is wary of the message and takes a cautious fleet formation. Yang takes advantage of the communications jamming between both sides of the corridor and tricks Mecklinger into withdrawing to the entrance of the Imperial side. The Bittenfeld fleet is lured into the corridor by Attenborough's fleet. Fahrenheit's fleet follows Bittenfeld, planning to overwhelm the Yang with numbers. Yang uses the superior numbers of the Imperials against them, forcing the Imperials to cluster together inside the tight corridor. High Admiral Fahrenheit is killed in battle preventing the complete destruction of the two Imperial fleets.

Attenborough's fleet lines the entrance of the corridor with mines. He plans to snipe the Imperial fleet as they come through small holes within the minefield. The Imperial fleet creates 5 entry holes through the minefield to establish a bridgehead. Steinmetz is killed in battle. The Imperial fleet movements are sluggish within the corridor. Reuenthal orders the Imperial fleet to feign a retreat. The Yang fleet approaches the Reinhard's flagship but is unable to penetrate the battle line. Both sides withdraw.

The Imperial fleets adopt a tactic of attrition via rotations. The Müller fleet, Mittermeyer's subordinates, Bittenfeld and many other Admirals rotate on the battle line. Yang's fleet, with less that 20,000 ships left fights on with no rotations in manpower. Bittenfeld's elite troops cause a fatal blow to Yang's fleet. Admiral Fischer, the one in charge of Yang's fleet maneuvers is killed in battle. Reinhard passes out from sickness. A ceasefire is announced. The Yang fleet passes out in Iserlohn.

Julian finds Yang's body. The Yang staff return to Iserlohn. The crew of Iserlohn enter mourning. Julian tells Frederica about Yang's death. It is decided by Yang's remaining staff that Frederica will assume the role of political leader. Julian is considered to be the next military leader. Julian accepts the role of military leadership after talking with Frederica. Unrest within Iserlohn grows and there is talk of desertion. Admiral Murai speaks with Julian and gives him his resignation. Murai intends to fulfill his last task for Yang by taking all dissidents from Iserlohn with him as a desertion leader. The remaining leaders of El Facil abandon the Yang fleet.

Reuenthal plans to execute Trünicht for any suspicious actions. Phezzan merchants notice Earth cultists entering Trünicht's home. Julian ponders how Yang became the personification of the spirit of democracy. Julian also realizes that he must ironically acknowledge the effectiveness of terrorism in history to shape Yang's death into something practical. Katerose and Julian talk about Fredrica. On August 8th, Space Calendar 800, New Imperial Year 2, the Iserlohn republic is born. The population comparison is 40 billion in the Empire to 940,000 in Iserlohn.

盟友キルヒアイスばかりか、宿敵ヤン・ウェンリーも喪ったラインハルトは、その喪失感を埋めるべく、日々の政務に励んでいた。ある日、ラインハルトはミッターマイヤーを前に、5年前の嵐の夜のことを語り出す。ロイエンタールは、門閥貴族の子弟を処刑したため軍刑務所に収監されたミッターマイヤーを救おうと、ラインハルトに助力を求めたのだ。これを機に、彼らはラインハルトに忠誠を誓い、数多くの武勲を立てることになる。

銀河帝国と自由惑星同盟の激戦場であったイゼルローン要塞。現在はイゼルローン共和政府の根拠地として、民主共和制を守る砦となっていた。ユリアンは軍司令官として、政治首班となったフレデリカを支えつつ、これから進むべき道を探る。遂にユリアンは、銀河帝国に立憲制を敷くことで、共和制の思想を広められないかとの考えに至る。それはヤンの教えではなく、ユリアン自らが考えた目標だった。そんな中、ボリス・コーネフがイゼルローンに驚くべき情報を持ち帰る。

帝国軍戦没者墓地の完工式で、ナイフを持つ男に襲われたラインハルト。取り押さえられた男は、自分はヴェスターラントの犠牲者の遺族だと叫ぶ。男は舌鋒鋭くラインハルトを弾劾する。ラインハルトは、盟友キルヒアイスを喪う原因となり、アンネローゼとの別離をももたらした自らの行為をふたたび眼前に突きつけられ、茫然と立ちすくむしかなかった。その夜、孤独と罪悪感に包まれていたラインハルトは、ヒルダに一夜の慰めを求める。

惑星ハイネセンのグエン・キム・ホア広場では、20万人の市民が集い、戦没者合同慰霊祭が開かれていた。新領土総督のロイエンタールは、杞憂と思いつつも2万人の警備兵を配置する。しかし、何者かの煽動により暴動が発生、双方に多くの死傷者を出してしまう。この事件を皮切りに新領土の各地で反帝国の暴動が相次ぎ、ロイエンタールは秩序回復に腐心する。彼は、この一連の騒動の裏に、帝国の権威のみならず彼個人の信望を失墜させようと企む陰謀を予感する。

ヒルダに求婚をしたラインハルトだったが、明確な返事は得られぬまま。鬱々とした気分を晴らすべく、乗馬や芸術鑑賞で日々を過ごしていた。そんな中、「ロイエンタール提督に叛意あり」との噂が流れる。一方、ハイネセンのロイエンタールのもとには「ラインハルトの病につけこみ、オーベルシュタインらが政治を壟断している」との情報が入る。ロイエンタールは、ラインハルトの真意を確かめるべく、皇帝に新領土への行幸を求める。

新領土行幸の途上、ラインハルトは惑星ウルヴァシーに降り立つ。大親征慰霊碑への参拝を済ませ、基地で休むラインハルトの寝所を叛乱兵が取り囲んだ。外部との通信も途絶する中、ルッツとミュラーはラインハルトを地上車に乗せて脱出するが、車中でミュラーはロイエンタールの謀叛を疑う。湖に着水したブリュンヒルトを目指す一行だったが、追っ手の数は多く、ルッツはラインハルトを逃がすため、自らが盾になると決意する。

惑星ウルヴァシーでの騒乱、そしてルッツの死を知ったロイエンタールは、ラインハルトとの間の亀裂が、もはや取り返しのつかない状況だと悟る。彼は謀叛を決意した。オーベルシュタインはさて置き、ラングなどの小者によって自らが追い込まれ、皇帝に弁明するなど、彼の矜持が許さなかったのだ。叛乱者としての途を選んだ彼の胸中には、無二の親友、ミッターマイヤーとの思い出が去来する。一方、ラインハルトもルッツの死を知り、遂に決断を下すのだった。

ラインハルトは、ミッターマイヤーにロイエンタール討伐を命じる。ミッターマイヤーは親友のために釈明の機会を求めたが、ラインハルトはルッツへの哀惜と自らの矜持を傷付けられた思いから、その願いを退ける。このままでは皇帝自らがロイエンタールを討伐せざるを得ないと、ミッターマイヤーは苦渋の選択を行う。同じ頃、ラインハルトはヒルダからラングの罪状を示した報告書を受け取る。それは生前のルッツが作成を指示したものであった。

宣戦布告がなされたわけではないが、既にロイエンタールの叛乱は規定の事実となっていた。にわかに戦略上の要衝となったイゼルローン要塞に、ロイエンタールの使者としてムライが訪れる。ラインハルト率いる帝国軍がイゼルローン回廊を通過するのを阻止してくれれば、旧同盟領の返還ばかりかトリューニヒトの身柄を差し出すとの申し出を、ユリアンは拒絶する。一方、叛乱鎮圧の勅命を受け、新領土に向けて進発したミッターマイヤーは親友と最後の交信を試みる。

ミッターマイヤーは「疾風ウォルフ」の名にふさわしく、迅速に艦隊を進めた。その速度はロイエンタールの予想を上回り、両者はランテマリオ星域で激突することになる。当初、ロイエンタール側が優勢だったが、ビッテンフェルト、ワーレンらが到着し、戦力は拮抗。戦線は膠着状態に陥る。そこに、イゼルローン回廊を通過したメックリンガー艦隊がハイネセンへ向けて進撃中との報告が入る。ロイエンタールは二正面作戦を避けるため、ハイネセンへ撤退を決める。

ハイネセンへ向け撤退するロイエンタール艦隊を、遂にミッターマイヤー艦隊が捕捉した。迫り来るミッターマイヤー艦隊に向け、ロイエンタールが先制の一撃を加えようとした、まさにその時、彼を裏切ったグリルパルツァー艦隊が背後から砲火を浴びせた。旗艦トリスタンが被弾しロイエンタールも重傷を負う。激痛に耐えつつ艦隊を指揮し、ハイネセンに帰着したロイエンタールは、総督府に入り、最後の仕事に着手するのであった。

総督府の執務室に入ったロイエンタールは、民事長官エルスハイマーに政務と事務の全権を委ねた。その後、参事官の地位にあるトリューニヒトを呼び出す。現れたトリューニヒトは民主共和制を嘲り、帝国を愚弄し、ラインハルトをも嘲笑した。ロイエンタールは銃を取り出し、なおも「演説」を続けるトリューニヒトを射殺する。夕闇が迫る中、ロイエンタールは従卒に命じてウィスキーのグラスを二つ用意させる。そして、静かに親友を待つのだった。

ミッターマイヤーは、新帝都フェザーンに戻り、ラインハルトにロイエンタールの死を報告した。ラインハルトは彼に「卿は死ぬな」と命じる。かけがえのない戦友を喪った悲しみは、ラインハルトも同様であった。ロイエンタールの忘れ形見である赤ん坊を抱いて我が家に戻ったミッターマイヤーを、愛妻エヴァンゼリンは快く迎え入れ、その子に「幸運」を意味するフェリックスという名を贈る。一方、ラインハルトはヒルダから懐妊を告げられたのだった。

新帝国暦3年の新年を祝う祝賀会の席上、ラインハルトはヒルダとの婚約と彼女の懐妊を発表した。二人の結婚式に参列するため、フェザーンまでの長い旅をしたアンネローゼ。キルヒアイスの死後、3年を経てようやく再会した姉弟であった。アンネローゼは、久しぶりに会ったヒルダにラインハルトを託す。1月29日、粉雪の舞い散る中、結婚式が盛大に執り行われた。しかしその最中、惑星ハイネセンにおいて反国家的暴動が発生したとの報が入る。

惑星ハイネセンでの暴動を皮切りに、新領土各地で騒乱が起こる。その原因は、何者かが流通を阻害したことによる物資の不足であった。旧同盟領の各惑星は、イゼルローン共和政府に救援を要請する。逡巡の末、ユリアンは民主共和政治を守る立場を明確にすべく、開戦を決意。ただちに艦隊を動かした。「イゼルローン軍、動く」の報は帝国全土に伝わり、ワーレンは艦隊を率いてイゼルローン回廊の出口に布陣した。ふたたび動乱の時代が幕を開けた。

要塞を進発した共和政府軍は、大方の予想を裏切って帝国本土側の出口を目指した。これを迎え撃つヴァーゲンザイル艦隊は、ユリアンに接近戦に持ち込まれ、大きな損害を出す。さらには要塞の正面に誘い出されトールハンマーの攻撃で壊滅してしまう。一方、旧同盟領側出口からはワーレン艦隊が進入するが、伏兵として待ち受けるメルカッツ艦隊に攻撃され、こちらも多くの艦を失う。部下の苦戦を見て、ラインハルトは自ら艦隊を率いて出撃するが……。

病床のラインハルトは、ハイネセンの治安を回復させるべく、オーベルシュタインを全権代理とし、実戦指揮官としてビッテンフェルトとミュラーを補佐に付けた。ハイネセンに到着したオーベルシュタインは、勝利に沸く市民を横目に、旧同盟関係者を次々と拘束。イゼルローン共和政府に、人質の助命は要塞と引き換えだと迫る。このやり方に反発したビッテンフェルトは、オーベルシュタインに掴みかかり、謹慎を命じられてしまう。

オーベルシュタインとビッテンフェルトらの不和は、ますます深刻になっていった。ミュラーたちは事態を収拾すべく奔走するが、遂にオーベルシュタインの直属部隊と黒色槍騎兵連隊が衝突する。幸い、ワーレンの活躍で騒動は鎮まったが火種は残った。一方、イゼルローン共和政府も対応に苦慮していた。だが、5000名もの人質がいる以上、フレデリカは帝国からの出頭命令に応じざるを得ないと判断。ユリアンらと共にハイネセンに向けて出発した。

旧同盟関係者が収監されていたラグプール刑務所で、何者かの扇動によって暴動が発生し、多くの死傷者が出た。ハイネセンへ向かう途中のイゼルローン共和政府の幹部たちは、暴動発生の報を受け、要塞に一時帰還して事態の推移を見守ることに。一連の報告を受けたラインハルトは、自ら事態の収拾に乗り出す。惑星ハイネセンに赴き政治犯を釈放した彼は、改めてイゼルローン共和政府幹部に対し、ハイネセンにおける会談を呼びかける。

フェザーンの憲兵本部に、テロを予告する謎の電話が入り、それと前後して爆発事件が発生、市内は大混乱に陥る。そして、アンネローゼと身重のヒルダが滞在している仮皇宮「柊館」を地球教徒が襲撃した。激しい戦闘の中、アンネローゼは身を挺してヒルダを守る。そこにケスラーが駆けつけ地球教徒を一掃、ようやく安全は確保された。しかし、このショックでヒルダは産気づいてしまう。病院に運ばれたヒルダは元気な男児を出産した。次代の皇帝の誕生である。

イゼルローン共和政府への亡命者を乗せた民間船「新世紀号」が、動力部に異常を来たし、救難信号を発した。これをきっかけとして両軍の衝突が起こる。後のシヴァ星域会戦である。帝国と対等の交渉を行うには一定の軍事的成果が必要と考えていたユリアンは、今がその時、と行動を起こす。一方、ラインハルトも自ら艦隊を率いて戦場に赴く。圧倒的な戦力差の中、無人艦を用いた詭計で帝国軍を翻弄するユリアン。その時、ポプランが驚くべき情報を持ち帰る。

「皇帝、不予」の情報を得たユリアンは、総旗艦ブリュンヒルトに強襲揚陸艦を突入させる。病床のラインハルトは幕僚に対し、ユリアンが自身の力で自らのもとにたどり着いたならば、対等の立場を認めようと告げる。ポプランが、マシュンゴが、シェーンコップが、自らの身を挺してユリアンの道を拓く。そして、ユリアンは満身創痍になりつつも、遂にラインハルトの前に立った。ラインハルトは、戦闘の終結を両軍に伝えるようミッターマイヤーに命じる。

遂に講和が成立した。喜びに沸き返るイゼルローン要塞だったが、そこに至るまでの犠牲も、また大きかった。ユリアンは、父、シェーンコップを亡くしたカリンに寄り添い、互いの気持ちを確かめる。帝国軍と共にハイネセンに向かったユリアンは、皇帝が不治の病に冒され、その命数が尽きかけていることを知る。一方、ハイネセンの病院に入院していたルビンスキーは、自ら生命維持装置を外す。次の瞬間、ハイネセンの市街は火の海と化した。

ラインハルトが新帝都フェザーンへ帰還する旅の途中、ユリアンは皇帝と数回にわたり会談を行い、具体的な講和の条件を定めた。フェザーンに到着したラインハルトだったが、容態は急変。死期を悟ったラインハルトは、ヒルダらに加え、ユリアンも仮皇宮に呼ぶ。そこでオーベルシュタインは、皇帝を囮にして地球教徒の残党を呼び寄せたと語る。最後の戦いが始まり、ユリアンはド・ヴィリエを撃ちヤンの仇を取る。そして、ラインハルトにも最期の時が迫る……。
