The most distant and disturbing world in the Pact system, Aucturn was once a living planet of shifting, organic flesh — a place where the very ground pulsed and breathed beneath a toxic atmosphere of hallucinogenic gases. Known as the Stranger, its surface was covered in fleshy ridges, orifices, and organic structures, and pools of black ichor dotted the landscape, transforming any creature that touched them into alien monstrosities called orocorans. The planet's ruler, Carsai the King, maintained a fragile order from the Citadel of the Black, while cults of the Elder Mythos — including the Pyramid of the Black Pharaoh dedicated to Nyarlathotep — competed with agents of the Dominion of the Black for influence over the world's unknowable purposes. Living settlements like Amniek, a tower-city where residents breathed filtered air and avoided the surface, clunged to survival alongside horrors like the Gravid Mound, a fleshy hill tended by sinister beings called the Midwives. In 324 AG, the terrible truth was revealed: Aucturn was the egg of a nascent Outer God now known as the Newborn. The entity that hatched destroyed the planet utterly, ending Aucturn's existence and leaving only a debris field and lingering psychic screams where the Stranger once orbited.
