Qella

this alien race has a rare, eighteen-pair genetic structure built from six unique building blocks and contained in 62 chromosomes, and communicated via a series of pitch-based transmissions. Their civilization had descended from the earlier Ahra Naffi, but had no children of their own when it was discovered that the two moons which orbited their homeworld of Brath Qella were on a collision course with the planet. The vast majority of the Qella agreed with the evaluation that the moons' impact would cause ecological ruin on their homeworld, while a few were adamant that the threat was being overblown. Those who understood and believed the threat created the starship which would later become known as the Teljkon vagabond, and created a device which could house vast amounts of data on what the Qella held as important and necessary information. It also carried the blueprints of how to genetically rebuild the Qella race, should that become necessary. These Qella dug deep tombs in which to hibernate during the foretold ice age. The ship departed Brath Qella about 120 years before the Galactic Civil War, just after the Old Republic had first discovered their world. The smaller of the two moons of Brath Qella impacted the larger, and the resulting storm of huge pieces of rock virtually destroyed the planet. The Qella who remained on the surface of the planet were killed in the ensuing - and almost instantaneous - ice age. By the time a survey ship could return to the planet, it was deserted. The Teljkon vagabond eventually returned to Brath Qella, shortly after the Battle of N'zoth, and began the laborious process of re-warming Brath Qella and making it habitable again for the Qella.
