Betrayed and burned alive by the 'Heroes', Mordain Veyl, the hated Black Sovereign, awakens in his past with the System of the Undead Sovereign. Mercilessly, he executes his enemies, reclaims fate, and leads the world into a new era. This time, the eternal throne belongs only to the Villain!

Cruel accusations branded him a cold-blooded tyrant who deserved to meet his end on the executioner's block. Yet fate granted him a second chance to reshape the throne of the Thalveron Empire. Ironically, an ancient curse distorts every sincere intention he has, forcing the young prince to appear increasingly cruel in the eyes of the very world he seeks to save.
