*The sky shatters, surrendering to an endless void choked with soot and ember. Magma geysers upward, consuming the earth as it gives way. From the chasms, a nightmare ascends—Zombiemen, Imps, and entities whose very names are blasphemy. The sole light is the inferno raging below. Survivors scatter in blind panic, their pleas lost beneath the jeering chorus of the invading swarm. No prophecy foresaw this cataclysm. Now, standing amid fire and bedlam, a single law governs all: you must survive.*
