Moon-beasts can see despite their lack of eyes and communicate via telepathy. Consummate slavers, moon-beasts use their supernatural abilities to curb rebellion or gain minions, but prefer regimens of torment and reconditioning to break their captives.
Moon-beasts build their stone cities upon the oily shores of the black seas on the dark side of the titular moon from where they hail. From there, they launch long, dark galleys crewed by almost-human slaves from Leng to seek new slaves and stranger wares. Moon-beasts see all other races as slaves, and often travel to the Material Plane for strange and frightening reasons, notably gathering suitable sacrifices for the eldritch deities of the Dark Tapestry whom they worship.
