The B'trillans were a squeaky-voiced, vaguely felinoid species native to B'trilla in the Gordian Reach sector. They were often encountered as laborers on other worlds in the Reach such as Feldwes, as well as in the Kalaminth, Spadja, and Thesme sectors, though their work ethic was not as well-regarded as their cleverness. They also possessed an agricultural colony on the drought-stricken planet Atorra.
