Eymorg
History:
Female inhabitants of planet Sigma Draconis VI who lived beneath the surface in the remnants of a highly
advanced culture. The male population, called the Morgs, lived above ground in primitive conditions in a wintery environment, existing only
to mate with the women, calling them the "givers of pain and delight." The Eymorgs were forced to return to the surface to live with the
Morgs when they were unable to find a humanoid brain to serve as their Controller.
