Sauric Relationships

Cassids, Banikans and Thanatians are all distantly related to each other. All three species evolved from an early reptilian being similar to cynadonts. While Cassids and Thanatians evolved to be more reptilian and avian-like, Banikans evolved into marsupial beings.

Due to their reliance on oxygen, these three races haven’t managed to spread out and colonize many planets.
