[Dark Western Fantasy Literature] + [Cthulhu Culture]
Our world is just a reflection that is about to be covered. In 1877, the chaotic mirror universe overlapped with the edge of reality, and irreversible "erosion" began. Reality is injected with weird rules, history is rewritten, and the human mind becomes the frontline battlefield. Everything you know is slowly mutating, and the only thing that is real is the growing whisper of madness. This is a battle of cognition about existence itself, and the price for the loser is to become a nameless corpse in the new world.
