Prince Arslan from the Kingdom of Pars finds himself into a predicament when a young prisoner from the nation of Lusitania holds him hostage in an attempt to escape.

Now fourteen years old, Arslan takes part in his first battle against Lusitania, and all odds seem at the Parsian army's favor, until his father, the King Andragoras III, falls victim to treason by Kharlan, one of his generals. (Source: Wikipedia)

Arslan is rescued by his loyal servant Daryun and they must run away from the Lusitanian forces, led by the General Silvermask, who ambush and capture his father personally.

As the Lusitanian army plunders the capital, Gieve meets the beautiful priestess Farangies, who is in search for Arslan. Upon knowing that Kharlan intends to raid the nearby villages in order to capture them, Arslan and his companions decide to take the fight to the enemy.

Kharlan continues his pursuit of Arslan, unaware that he fell for Narsus' scheme and his forces are ambushed in an unfavourable terrain, where Arslan's party meets Gieve and Farangis, who join their cause as well. Meanwhile at the capital, Silvermask confronts the captive King Andragoras, revealing his identity and motives.

Arslan's small group is reunited at Peshawar and they begin looking at using the army there to take back the rest of Pars.

Rajendra asks Daryun to be his proxy in the duel before the gods to determine the next heir to the throne of Sindhura. Faced with the fearsome knight in black, Gadevi arrives at a terrifying solution.

Étoile wrestles with the knowledge that the prince, whose head he had wanted for so long, was someone he knew. And the battle for the Keep of Saint Emmanuel continues.

Arslan's army deals with the aftermath of the battle for the Keep of Saint Emmanuel.

The Kingdom of Turan decides to take advantage of Pars's moment of weakness to invade, forcing Arslan to abandon his plan to retake Ecbatana in order to secure the border at Peshawar.

The Turanians regroup and prepare to make another attempt to take Peshawar Fortress, this time, using more underhanded means. Meanwhile, Andragoras makes good his escape from Ecbatana and the Lusitanians.

As Hilmes continues to pursue the treasured sword Rukhnabad, he comes across someone from his past. In the meantime, in Peshawar, King Andragoras sets Arslan a task that is seemingly cruel and impossible.

The bulk of Arslan's people set out for an uninhabited island in search of hidden treasure, but back in Gilan, there is still the unresolved matter of the mastermind behind the pirates.

With the arrival of Étoile and Merlane, Arslan learns of the situation in Ecbatana. And while he is still far short of amassing an army of 50 thousand, he must decide whether to act upon this information or not.
