The Nirrani tribe was a Tarasin irstat that lived on the planet Cularin during the time of the Clone Wars. The Tarasin Kaylanna served as the tribe's Irstat-Kes and when Jedi Master Darrus Jeht summoned the Tarasin leaders to hold a vurgat ceremony, Kaylanna represented her tribe at the proceedings.
