Two centuries ago, the hanar helped 375,000 members of the drell race migrate to the hanar homeworld, Kahje, to escape the environmental extermination that had claimed the remaining 11 billion drell.
Nearly all drell demonstrate tremendous loyalty to their famously reclusive saviors. The intimacy of their relationship, expressed in a formal sociopolitical alliance called the Compact, also results in extremely close personal relations in which some drell actually learn hanar Soul names. While most drell reside on Kahje, some assist hanar off-world as envoys, researchers, co-investors, wayfarers, assassins or otherwise, eager to help their saviors. For a century, galactic wisdom has held that behind any high-ranking hanar hides a resourceful and fanatically devoted drell.
The omnivorous, reptilian drell possess an average life span of 85 galactic standard years. Having evolved on an arid planet, drell face serious illness on the hanar homeworld, especially Kepral's Syndrome, a fatal bacterial lung disease.
