- Description from novelbuddy

On that fateful day, a voice in the sky told everyone on Earth that the world they called home has just been part of some sort of simulation.

After making a deal with a peculiar goddess, Victor awakens in a new world of swords & magic with a body of pure darkness and far too many eyes.

He had become a Netherborne—the strongest undead race in all of existence.

But what happens when a human mind inhabits such a creature? With dulled emotions and an insatiable hunger?

Does only death and destruction await the world? Or will Victor be the herald of a new undead civilization?
