Sentinel (Jedi)

The Sentinel was a Jedi Knight and member of the Jedi Temple Guard before the fall of the Jedi Order. He bore a striking resemblance to that of the Grand Inquisitor, who served the Galactic Empire after its rise to power. During the era of the Empire, Kanan Jarrus encountered the Sentinel in the Jedi Temple on Lothal, where the Sentinel warned Jarrus about how his Padawan, Ezra Bridger, could be called to the dark side of the Force. After a brief lightsaber duel, at the end of which Jarrus refused to fight, the Sentinel proclaimed Jarrus to be a Knight of the Jedi Order. The Sentinel then encountered two Inquisitors, the Seventh Sister and the Fifth Brother, in the Jedi Temple.
