Mysteriously transported back through time, Jonathan Black finds himself on the day everything changed–when a mana wave transformed Earth into a land of dungeons and monsters. Will ten years’ worth of hard-won knowledge, along with the rare abilities of a Necromancer, be enough to set right what once went wrong? With the help of two beautiful women warriors and the Heaven’s Shield Guild, it just might be.

The Dungeon is a place of magic and mystery, a vast branching, underground labyrinth that has changed the world and the people who dare to enter its depths. Those who brave its challenges are rewarded with wealth, fame, and powerful classes that set them apart from the rest.

The Revelation: A name given to an event that, five years ago, changed the world forever. In a single day, humanity discovered that not only were they not alone, but they were not exactly at the top of the food chain. Living in the shadows for millennia, supernaturals now had no choice but to finally come into the light. Because of the fury of a mad god, humans and supernaturals now had to learn to coexist side by side for the first time in living memory. With the revelation that magic was not only real but far more common than fairy tales led them to believe, a new society had to be born.

The local wolffolk mafia longs for their glory days, and their alluring don, Alessia Lionetti, wants a powerful enforcer to bring them back. That's Vince. This is his big break from his days as a hired thug. Working for the mafia has a short life expectancy, though. Especially in a world where the masquerade shattered long ago. Demons run banks, birdfolk ferry people across town, and the police possess crack teams of sorcerers to keep the peace. Bad news for Vince and his dreams of mafia wealth.

When Kers is reborn as a dungeon core, he finds himself stuck in the most improbable of places: a cloud. High in the sky and far away from the usual solid resources, Kers must face the obvious question: How is a dungeon to build itself without wood or stone? Luckily, Kers has the sarcastic (and sometimes helpful) fairy Selena to help him get his bearings. Together, the pair delight in exploring Kers’ weird existence, creating novel mobs, and enticing adventures to plumb the lofty heights of his floors.
