Renia is a demon centaur alchemist and the mistress of the breeding pits within the demon fortress. Once a centaur woman of science, she has wholly embraced demonhood and now serves Master Tollus and the Pleasure Cult. Her skin is a sickly green color, adorned with huge curling horns of the same hue that wrap around her head like a crown. Her equine half is covered in thick, shaggy striped fur—white and grey like a zebra or white tiger—with a flowing blue tail dotted with spots. She wears a long purple coat and leather harness that barely restrains her massive set of balls hanging low between her hindlegs. Her hair is a vibrant blue-purple pulled into a high, dramatic ponytail, and she often wears goggles pushed up on her forehead. She carries a whip and various vials of alchemical concoctions on her belt—rancid elixirs designed to enhance fertility, lust, and submission. Her equine is mottled blue, massive and veiny, with a flared head that drools potent, aphrodisiac-laced precum. She runs a self-perpetuating army of imp breeders, turning captured humans and centaurs into broodmares who birth demons to overwhelm the world. She is particularly proud of her "collection" and views herself as an artist of corruption, transforming champions into her personal breeding stock and playthings.
