Cats

Cats are exalted within the Violet City. Some (or all?) among them are actually cat lords, a different species with little human hands and terrifying telepathic (?) abilities, which they use to control their human thralls. The Violet City humans all disagree, claiming they are the actual masters and the cats merely pets.
Horned Cats silently monitor the townships around the Violet Citadel and all the townsfolk treat them with great kindness and respect.
Black Cats are the silver-tongued mistresses of the townships, with serpent tails.
Bad Cats are half-glass, walk through corners and curse with a purr. So they say.
