After her negatively portentous birth, however, she was never fully accepted by her superstitious peers and instructors at the Dungeon Assistant Preparatory School. Nevertheless, she persisted in her studies and graduated at the top of her class. Unfortunately for her, the “hands-on” training she was supposed to receive from a mentor and his bonded Dungeon Core didn’t go the way she would’ve hoped.

Jake is working at the neighborhood market under his apartment when the world ends.

And suddenly, everyone has access to a new, strange magical card system that gives them magical powers.

Milton Frederick never had the chance to live out his life as a professional gamer on Earth, mainly because he was abducted by aliens. Unfortunately, he wasn’t returned home after the typical probing associated with such things to tell an unbelievable story to his friends.

Larek Holsten is different from most people living in the Kingdom of Androthe, where his seven-foot-tall frame is looked at with suspicion and anger from its shorter residents; but as long as it helps him become the best Logger he can be, he doesn’t let it bother him all that much. He and his best friend, an axe with a powerful Fusion that causes it to become sharper and stronger than a normal tool, are feared by the trees in the magical forest north of his home, as he can fell the quickly growing monoliths faster than anyone else in the community.

Thousands of Heroes protect the land, defending against the periodic incursions by gigantic monsters known as World Threats. This was the way it had always been and Clay Shuntwise was perfectly fine with that. Running deliveries for his family’s shop in the sleepy town of Renton, the young teenager barely even thought about Heroes and their role in keeping the world safe. That was, at least, until a World Threat came crashing down on him.

Elmer Robbins loved decorating for every holiday with his wife, Mary, by going all out with décor at their cozy little house as well as filling his office with holiday cheer.

In a flash, every human-erected construction on Earth - from Buckingham Palace to the tiniest of sheds - collapses in a heap, sinking into the ground. The buildings and all the people inside have all been atomized and transformed into the dungeon: an 18-level labyrinth filled with traps, monsters, and loot.

Millions of dungeons inhabit the planet, utilizing the Human people as a source of much-needed Mana to facilitate their own growth; in turn, the humans delve into the dungeons to acquire their own power in the form of Essence, which allows them to develop and enhance themselves in a multitude of different ways.

Throughout the Kingdom, Defenders constantly fight against incursions of dungeon monsters rampaging over the border the Kingdom shares with the Wildlands. To keep the danger to their citizens low, they periodically sweep through these untamed areas filled with natural beasts and roaming dungeon monsters, destroying as many Dungeon Cores as they can find.
