Hime to En'yoku no Imperium

Feared as the "Warlock of Destruction," Lucius, the protagonist, once unleashed chaos upon the world with his immense power. Defeated at the hands of the Hero and sealed away, Lucius would awaken once more after a thousand years of slumber.

The catalyst for his awakening was Irena, the first princess of the Noxheim Empire - a nation that dominated the continent with its military strength and advanced technology.

Sensing that an unknown power within Irena had roused him, Lucius plotted to make use of it to restore his diminished strength and lost memories to complete his return. However, as an imperial princess and a descendant of the Hero, Irena rejected Lucius, refusing to align with the "Warlock of Destruction." To force Irena into undoing the seal, Lucius began a ritual intended to lay her heart bare and bring her under his control through humiliation and pleasure.

What drove Lucius to become the "Warlock of Destruction" a millennium ago?
Why does Irena hold the power to unseal Lucius?

The warlock of a thousand years past and the imperial princess. Their encounter would entangle the schemes and ambitions of many, and ultimately reveal the empire's hidden truths...
