When Michael Walters awakens inside a dungeon, he's not aware that it's only the beginning to a world of horror. Monsters have appeared all across the Earth, savaging the populous. The only hope anyone has is the appearance of the mysterious World System, a vast conjuring of immense scale and power. But even that isn't enough to fully stem the tide. After all, the System doesn't care if you survive.

With such lackluster support, it is up to the survivors, including Michael, to secure their futures. Facing possible extinction and unable to stop quarreling amongst themselves, humanity is but steps into the apocalypse.

In a dying world, anything can kill you, and survival always comes with a cost.
