The Demogorgon is a creature frequently played by Will and his friends in Dungeons and Dragons. According to D&D literature, the Demogorgon, a powerful demon prince, is "one of the most terrifying of monsters, but also one of the best-known demon lords in the D&D game". Beyond D&D, the creature's origin is allegedly written on a Latin poem called Thebaid, attributed to a fourth-century Christian scholar named Lactantius Placidus.
