Relgarians were Sebaceanoid in shape and size with whitish skin that has blue highlights. Their gums were blue, and the one female who was observed had what appeared to be a smooth blue oval stone implanted vertically between her completely black eyes. The stone's color matched the ends of her otherwise white hair.
Relgarians were known as a peaceful race of explorers who treated Leviathans and Pilots very well. They used the living ships to journey into completely unknown areas of deep space. The one Relgarian encountered was brilliant in mathematics and physics, but nothing else is known of the species.
Linfer was a Relgarian.
