Rivvi

The term Rivvi collectively describes the dominant intelligent humanoid species on Dione. The Rivvi are composed of numerous races and sub races, each characterised by distinct anatomical, physiological and cultural traits, while sharing a common evolutionary origin.

They are broadly separated into two groups: the Beasts include Rivvi with animalistic features like furred ears, tails or other features close to animals, while the Koma represent distinct Rivvi lineages characterised by naturally developed horns and tails that do not fit any other animals.
