Umbrites are robust bipeds averaging 1.6 to 2 meters tall, with blue skin, deep-set eyes and a set of powerful pincers on their faces. Descended from a species of subterranean tunnelers, Umbrites are impressively strong and well-adapted to low-light conditions. They are very muscular and strong, and tend not to speak very often. Because of their physical adaptations for strength and sociological characteristics of warren living, they are one of the few Commonwealth species that is ideally suited for space travel.
