These pages look at those elements that are almost always mentioned in relationship to the King in Yellow – sometimes they are more important to the stories than the King himself. Collectively we are referring to these as factors of The Carcosa Mythos.

The latter is a name worthy of but a minor mention or three in the original stories in The King In Yellow (The Book), but has become significant since thanks to his/its(?) appropriation by The Cthulhu Mythos.
