Carnival of the Black Elves
The church of Lloth was slow to take hold of the Black Elves early in the history of Ethear, one of the reasons being their snake headed whips often perished in the alien atmosphere. Over time various alien breeds of snakes were adapted , bred and forced into surviving on Ethear.
So the Serpent cults managed to gain enough of a foothold to be able to have Imperial Patrons, mastery of the complex workings of the portals connecting the major features and cities of Ethear.
