Kunor Bann was a male Human Jedi Knight from the era after the Second Galactic Civil War. In 44 ABY, Bann was afflicted by a psychosis caused by the dark side entity Abeloth, leading to the delusion that everyone around him had been replaced by imposters. This psychosis took hold while he was within the Jedi Temple, but the Jedi there apprehended him and imprisoned him in the Jedi Temple detention center. Jedi Master Cilghal authored a report detailing Bann's psychosis, along with that of another Jedi, Turi Altamik, who was experiencing the same affliction; in it, she expressed her concern that the number of Jedi succumbing to this psychosis was increasing rapidly. However, before much time passed, Luke Skywalker, the exiled Jedi Grand Master, successfully completed his mission to kill Abeloth, which immediately ended Bann's psychosis.
Bann subsequently played a role in the rescue attempt aimed at freeing Valin and Jysella Horn from Galactic Alliance Security custody. As a member of "Team Saav'etu," Bann established a defensive position outside the bunker where the Horn siblings were being held, aiding in repelling attacks from GAS personnel.
