The Spawn of Yog-Sothoth are creatures derived from the Dunwich Horror by Chaosium for their Call of Cthulhu roleplaying game.
Background[]
The Spawn of Yog-Sothoth are thoughtless squirming masses of flesh, tentacles, eyes, and tails, along with extra maws in places where joints or vertebrae would be expected. They are amorphous and can fit through most gaps, pulling themselves through with tentacles. They notably emanate an unpleasant scent, typical among old ones and relations. In addition, they possess a weak form of invisibility, allowing them to pass in the dark without drawing attention. They quickly grow to enormous size, and if they continue to feed, they will continue to grow but at a much slower rate. Despite this, their cognition never improves to be much more developed than that of a toddler. Due to this, they are not capable of complex decision making, more motivated by short term instincts than their cousins'. They are capable of magic but rarely use it for more than fundamental rites. The ancient Spawn of Yog-Sothoth can be as large as buildings or small hills; however, they are generally dormant at this size to preserve energy. If killed, their flesh rapidly melts, and soon only a crusty stain remains. Creating a Spawn of Yog-Sothoth involves a blasphemous ritual in which a humanoid or animal is used as an incubator, a Child of Yog-Sothoth's seed combined with the blood of a member in a pact of Yog-Sothoth. The mother dies upon giving birth and usually gives birth to twins, a Spawn of Yog-Sothoth and a Child of Yog-Sothoth. If twins are not produced, the offspring are still birthed.
