The Primal Demon Door is a Demon Door in Fable: The Lost Chapters and Fable Anniversary, and was the first Demon Door ever made. Created to guard the Fire Heart, which calls upon the Ship of the Drowned. This was the sealing place of the prophet, and if The Hero chooses so, their graves. To get the Fire Heart, you must solve a puzzle in which turning all tiles to moon will kill a prophet and turning tiles to the sun will free a prophet. Despite their plan to tell you that if you kill them you will never get the Fire Heart, you can anyway.
