Oma

Oma was the homeworld of the Omaan race. The planet was tropical and humid, perfect for hairless primates and reptilian-like species. A common evolutionary trait due to the general overpopulation of Oma, most of it's inhabitants were very aggressive, and were lethal. Any native species would have to fight to survive, and natural life-expectancy was halved, at least. The Omaan, upon becoming sentient, had allowed such instinctual behavior to evolve into bloodlust and an extreme desire for war.
