Utani Xane was a Kallidahin who served as a curator of Quarantine World III, a quarantined planet which housed the dangerous Triple-Zero personality matrix. When the archaeologist Doctor Aphra attempted to steal the matrix from the world, Xane confronted her with a group of B2 super battle droids and reclaimed the stolen object. The Sith Lord Darth Vader then arrived on Quarantine World III searching for Aphra, whose help he desired. Xane protested the Sith's presence on the world, as it broke several treaties, but was then killed by Vader along with the battle droids.
