The Ritha are one of three early alien species encountered by the early TOG Empire. TOG was extremely xenophobic during this period and quickly conquered all three alien species, forcing them to be settled across the Empire in small colonies designed to prevent them from acquiring enough genetic diversity to survive as a species. The plan worked. The only surviving members are rumored to wander the spacelanes as a sort of "Space Gypsies" trying to eke out a living as nomadic traders. The Ritha now exist as a near-extinct species.
