Reborn as the Fated Villain

Damien Nightshade, a discarded royal masquerading as a Professor in one of the continent's greatest magic academies, is considered a mid-level boss—one fated to die in every playthrough. Now, I have transmigrated into his body. A game-like world has become my reality, and instead of being its hero, I'm cursed to die a pitiful death as a fated villain. But why should I accept life as a third-rate villain when I can strive to become the unbeatable final boss?

With a half-frozen fortress, a vampire sister who hits like a natural disaster, and a blood-drinking dryad fertilizing his fields, I have everything I need to found a kingdom. All I have to do is outmaneuver a werewolf plague, keep a wind mage addicted to my blood-spiked drugs, and survive a royal court full of nobles who smile while they plot my execution. I've played this game. I know how every major event is supposed to go. The problem? I've already changed too much.
