Sacha Swiftbird was a Human female with sensitivity to the Force; she earned a living as a pilot in the dangerous sport of podracing.
During the Clone Wars era, she joined the Antarian Rangers, a paramilitary organization allied with the Jedi. After the Galactic Empire rose to power, she participated in the Rangers' efforts to resist the new government. Swiftbird was stationed at Mountain Home, a secret underground base of operations for the Rangers located on the planet of Toprawa.
In 18 BBY, she became involved in Jedi Knight Jax Pavan's mission to liberate Thi Xon Yimmon, a Cerean who led the Whiplash resistance cell, after Yimmon was captured by Darth Vader, the Sith Lord. After Pavan disappeared, Swiftbird, along with Pavan's associates Den Dhur and I-5YQ, organized their own attempt to free Yimmon. They traveled to Kantaros Station, the facility where Yimmon was imprisoned, and infiltrated the space station by disguising themselves as members of the criminal syndicate Black Sun. After uniting with Pavan, who was independently conducting his own rescue operation, Swiftbird used a lightsaber to kill the Imperial Inquisitor Probus Tesla while Tesla was engaged in a duel with Pavan. Swiftbird and her allies then liberated Yimmon and departed on their starship for the world of Dathomir, where Pavan had dealings with the witches residing there.
