Thisspiasians were a serpentine species, distinguished by their long snake-like bodies and thick beards, that were native to the planet Thisspias. Thisspiasians had four sets of arms, but a pair of them were often hidden beneath their clothing. Thisspiasians sleep for a couple of hours per day, however their main form of rest is a type of trance that can last for minutes or hours. The trance provides neurological repair. If a Thisspiasian misses the trance, they can become emotional and irritable.
