Voormis: Voormis were possibly transplanted here via the Serpent Men or via some unconfirmed portal or gateway deep from within Mount Voormith'adreth. On this world most have taken to the worship of Shub-Niggurath, though some spread across the world still worship Tsathoggua.
They often sacrifice humans (that they do not eat or mate with) to the dark goddess in the mountain. Over thousands of years the Voormis have developed a trait that makes most Shub-Spawns react more pleasantly to their presence or at least ignore them.
