Return of the Apocalypse-Class Death Knight

Damian Haxen was a man born with a talent destined to go down in history. However, he was transformed into a Death Knight by a dark mage, Archlich Dorgo, and was forced to live like a slave. By the archlich's command, he slaughtered his family with his own hands and brought ruin to every kingdom. Just as the entire world was about to fall under the archlich's control, Damian regained his consciousness, but it was already too late. Right when he was ready to give up everything, a miracle happened: regression. Now back to the time before it all began, his goal was clear.

"This time, I'll live only for my family's happiness and future. Of course..."

He would purge all traces of the filthy dark mage and make him taste hell first!
