Giygaxian Pantheon

Henceforth, the Ancient Ones live on the other side of the Gates, in the corners between worlds known to man. They wander outside the sphere of the Earth in the eternal expectation of the hour when They will be able to return to Earth: for the earth has known them and will know them henceforth at the appointed hour.
' The day is replaced at night; the day of man will pass, and they will again reign in their former possessions. You will know their dirt and abomination, and their curse will fall upon the Earth.
