Although they’re generally humanoid, the Memish have pitch-black eyes, and skin that comes in various shades of blue, purple, and green. Instead of hair they have tentacles. The Memish are able to survive at extreme depths, and navigate waters with virtually no light available.
They’re known for organizing in complex, extended family groups, and practicing their religion away from the light of the Holt star. It involves ritual carving of their scaled hides and imbuing the carvings with carefully tended bioluminescent deep-sea plant life.
