The Thirteenth Coven – the Thirteenth Coven worships an aspect of Slithian Vor known as the Brood Mother. In the guise of the Brood Mother, Slithian Vor is depicted as a perpetually-pregnant and swollen-bellied woman whose grin promises lascivious pleasure. This aspect is also sometimes known as the Mother of Monsters, for she represents the spawning of inhuman beasts and frightful slithering horrors. Indeed, only women still capable of bearing children are admitted to this cult. Once they are part of the Thirteenth Coven, its members strive to summon demons from the World Below to mate with willingly; each woman who belongs to the Thirteenth Coven longs to be impregnated with a devil-spawn, for such is looked upon as a boon and a blessing from their demonic goddess. Beings frequently summoned by this cult include incubuses and all manner of male demons or devils.
