Sentient Milieu

The Sentient Milieu was an association of starfaring races that existed 25,000 years ago. It was formed over the course of several thousand years to "mutually enrich their respective cultures, to provide a safe creche for emerging sentient species and to afford themselves a degree of protection from external hostilities via military alliance," as the Melnorme put it.

The seven major members of the Sentient Milieu were

• the Drall, one of the four founding members
• the Faz, joining about 22,000 years ago
• the Mael-Num, one of the four founding members
• the Taalo
• the Ur-Quan (still one race at that time), the last major race to join
• the Yuli
• the Yuptar

The Milieu may have incorporated other races, as the Melnorme refer to the "seven most active Milieu members", but they are unlikely to have played an large role. The Ur-Quan Kzer-Za refer to the "six races of the Sentient Milieu" and the Ur-Quan Kohr-Ah plainly refer to "all six of the other races in the milieu". There are no other known references to additional Milieu members.
