Shadows in the Void
Yuggoth is a desert planet just inside of Light’s Edge with three cities dominating its surface: Vaes Astrid, Vaes Tarkaren and Vaes Domnis. Being so far from a star, the planet is actually quite cold, but with so little water the conditions remain dry.
Each city is named for its vampiric prince/princess and each city is a sprawling slave market where the Blood Slavers sell their chattel and others sell services to go along with them.
Needless to say, between the dark, the cold and the slavery, Yuggoth is not a happy place.
