The Imperial Security Bureau was a secret task force active after the formation of the Empire. The group, led by officers like Agent Kallus, investigated and looked to squash any rebel activities found throughout the galaxy. The ISB took special interest in a small band of Lothal thieves, whose attacks on Imperial outposts marked the signs of rebellion.
The Imperial Academy on Lothal was a high-tech, heavily fortified training facility designed to shape cadets into ruthless stormtroopers. Inside the Imperial Academy was the Well: a difficult, programmable obstacle course that tested the intelligence and strength of the cadets. Commandant Aresko and Taskmaster Grint served as the academy's unforgiving instructors, driving trainees to win at all costs.
Not much is known about the Empire’s Grand Inquisitor. A Pau’an male, he was tasked by Darth Vader to hunt down any surviving Jedi Knights. The Inquistor was an intimidating figure, dressed in all black and wielding a red, double-bladed lightsaber. After several encounters with Kanan Jarrus and his Padawan Ezra Bridger, the Inquisitor died in a lightsaber duel with Kanan – but warned the rogue Jedi that his victory had unleashed something terrible.
Zare Leonis found a kindred spirit in Ezra Bridger, as both were undercover cadets at the Imperial Academy with no love of the Empire. Zare showed impressive skill as a cadet, but his true goal was to find out what happened to his sister, Dhara -- a star trainee at the Imperial Academy who mysteriously vanished. Zare helped Ezra uncover an Imperial decoder and escape the academy, but remained behind as a spy.
