Eldritch horrors descended from the sky to consume the world. Only a last-minute intervention by a mysterious Hegemony of Worlds saves Earth, albeit temporarily. Skills, levels, and battles with twisted monsters are part of the new reality the survivors will have to face.

Augustus Finn wakes up after surviving countless terrors. He is thrown directly into danger as a twist of fate places him in an area designed to contain and dispose of eldritch lifeforms - areas also known as dungeons. He will have to compete with monsters, alien Peacekeepers, and his own inner demons if he is to survive.
