|The Duel on Stygeon Prime, also known as the Encounter at Stygeon Prime, was a confrontation in the Spire, a prison on the planet Stygeon Prime, between the Galactic Empire and a group of Lothal-based rebels who carried out an insurgency against the Empire's rule. The duel, primarily fought between former Padawan Kanan Jarrus and the Jedi hunter known as the Grand Inquisitor, took place in the fifth year before the Battle of Yavin, as part of a mission to rescue Jedi Master Luminara Unduli from Imperial captivity. The rebels learned that Unduli, a former member of the Jedi Council, had survived the Clone Wars and the ensuing Great Jedi Purge, and was being held prisoner by the Empire. However, Unduli had in reality been executed by the Empire years earlier and the residual Force essence within her bones was being used to lure surviving Jedi to their deaths. The Grand Inquisitor, the Imperial Jedi hunter who killed Unduli, intended to trap the rebels in the Spire and kill former Padawan Kanan Jarrus and his apprentice, Ezra Bridger. The rebels infiltrated the Spire after arriving on Stygeon Prime and made their way through the facility. Jarrus and Bridger located Unduli's cell, where they learned she was dead and that the Inquisitor was waiting for them. Jarrus and the Inquisitor engaged in a lightsaber duel, during which the Inquisitor attempted to turn Bridger to the dark side of the Force. When the boy refused, the Inquisitor aimed to kill them both, but they were able to flee and, ultimately, escape the facility with the other rebels. The Inquisitor would nonetheless continue hunting them, intending to destroy them and all remaining Jedi.
