Skonnan

The Skonnans were a race of humanoids from Skonnos. They are indistinguishable to humans.

History
They once ruled a massive interstellar empire, controlling hundreds of planets, but there was a massive civil war and the empire collapsed. This caused the death of nearly all of the scientists and men of learning, which left the military to control Skonnos. This also lead to the decay of most of Skonnos' technology, leaving them with a broken down star ship fleet.

Eventually, the Skonnans were discovered by the Nimon, who promised them a new empire in exchange for sacrifices of living beings and hymetusite. They gathered these sacrifices from Aneth, an old subject of the Skonnan Empire. Though Skonnos and its new leader Soldeed obeyed the Nimon's will, the Nimon were eventually defeated by the Doctor and their Black hole generator was destroyed. Their hopes for a quick imperial revival and a return to military glory ended for the time being.

Culture
The Skonnans were warrior race obsessed with glory and military conquest to the point of religious fever. Many people are seen wearing elaborate martial costumes consisting of black uniforms with black helmets sometimes with tall feathered plumes. Since no women were shown in uniform their armies must have been male dominated hierarchies.
