Ceiphians are humanlike Thilians. They possess no fur on their body except on the top of their head. Their ancestry dates back to the Yluxa event, where, amongst all the mutated offspring, the first Ceiphian emerged. Sey, who was the first Ceiphian, was found in the town that was close to Yluxa immediately after it had gotten re-established.
The Thilian organs of the Ceiphians are different in their abilities, the most prominent is that they cannot spew fire like Celestial Thilians, Cyrathilians and Kybrothilians.
