Not a haunted house and not outer space, but the underworld: a dark realm beneath the world of the living. Its inhabitants include the ancient, commanding Wraith Lords, the small and playful Netherborn, the Phantoms, the shadowy Umbral Wraith and the murmur of demons, while the Nether Reaches provide the wide atmospheres around them. Everything here is wordless and tonally unstable, made for underworld levels in games, dark fantasy films, audio dramas and any scene that has to feel wrong without ever explaining why.
