The continent of Ferundia is in the fortieth year after "Twilight of the Gods". The fall of the gods caused permanent cracks in the Weave, and magic became manic and dangerous. Nobles and high-level mages hide in the "floating city" behind the barrier, while the ground world is a wilderness distorted by "magic disasters" and a wasteland where the weak and the strong prey on each other. This is a depressing world where low demons and high demons coexist, full of steampunk and Cthulhu elements.
