After subjugating Starck, Waldlind barely pauses before invading Altirk. Villar joins forces with neighboring domains Kilhis, Regalia, and Haman to repulse Waldlind, but then a new enemy arrives from the seas. It's Milza Kuches, price of Dartania, who once looked up to Villar. Milza has forsaken Villar, instead becoming Marrine's sword. And with the Dartanian fleet in tow, he's about to unleash a furious assault on Altirk.

As the uprising escalates under Theo, assuming the name of the hero, Cornaro, Phederico begins to feel threatened. Giving his eldest son, Dorni, five thousand troops, he orders him to subjugate Theo and quash the rebellion. And behind the scenes, the Black Witch, Jana, has a secret plot up her sleeve.

As the Altirk Treaty moves foward, it declares independence from the Union. The Treaty vows to broker peace with the Alliance and Union by becoming a third force, and carrying out Villar's wish.
