[Dark Western Fantasy] + [Cthulhu Mythos]
Our world is merely a reflection about to be overwritten. In 1877, a chaotic mirror universe overlapped with the edges of reality, and an irreversible “incursion” began. Grotesque rules seeped into reality, history was rewritten, and the human mind became the front line. Everything you know is slowly mutating. The only thing that remains real is the ever-growing murmur of madness. This is a cognitive war fought over existence itself, and the price of defeat is to become an anonymous corpse in the new world.
