The Medjel are a 'companion' (or slave) species to the Idirans. They originally evolved in a social symbiosis with the Idirans, who later bred them as a companion species over the course of forty thousand years (by the time of the Idiran-Culture War). They are reckoned to be about two thirds as intelligent as the average human. Outnumbering Idirans by about 12 to 1 but being genetically loyal to them, they provide good, if unimaginative, soldiers and servants.
Physically, the medjel are about two metres long, with green-brown skin. They have flat, long heads with distinct muzzles, walk on four feet and use two front feet as hands. The tail of the military medjel is docked.
