The Apocalypse-Level Death Knight Returns

Everyone's talking about how troublemaker Demian Haxen's suddenly become a devoted son and brother. What they don't realize is that he's returned to the past after spending decades as the brainwashed death knight of Dorgo, the archlich who murdered Demian's family. Given a second chance at life, Demian's out to power up and protect his family to defeat Dorgo when he comes to conquer the world. But will Demian alone be enough to prevent the apocalypse? Or will his failure mean death for them all? (Source: Tapas)
