Tenebran

Tenebrans (sometimes referred to as Tenebrites) are the sapient native inhabitants of the planet Tenebra, orbiting the giant star of Altair. When first contacted by Humans and Drommians; they were a primitive society, akin to the neolithic period of Earth's history. The Tenebrans are large creatures of slightly conical shape, four pairs of limbs, and quill-like visual organs located near the crest of their heads. They breathe oxygen, but their metabolism is quite unlike that of Earth creatures; it is unclear whether they are carbon-based or not.
