Planet of origin: planet Torkarga in the Lesser Magellanic Cloud (the Third Galaxy).
Tokarga is quite earthlike and possessed at least a moon until it was (they were?) destroyed by the Mazones and turned into a ring around the planet.
Advanced humanoid civilisation whose development was influenced by the Mazones who settled on the planet in the distant past and kept one of their seeding plants in the planet’s ocean. The planet was destroyed by the Mazones after a insurrection in 2977. Tokargans are sexuate, hairless, slightly smaller than humans, with a greenish skin and no apparent neck.
