The Tarro were a race of beings that originated from the Til system, on the planet Tililix. When the Til star exploded, the planet Tililix was destroyed. Only those Tarro off-planet at the time survived. An estimated 350 Tarro exist in the galaxy, all of them descendants of the Tarro who had survived the destruction of Tililix. The Tarro were a humanoid race characterized by their dark green skin and piercing yellow eyes. They had heptadactyl hands, and were heavily muscled. They were formidable fighters and weapons-masters, and were known for their stubborn, independent natures. Little was known of their history and culture, given the cataclysmic reduction of their species.
