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.
The wedge-shaped Imperial Star Destroyer is a capital ship bristling with weapons emplacements. Turbolasers and tractor beam projectors dot its surface. Its belly hangar bay can launch TIE fighters, boarding craft, land assault units, hyperspace probes, or be used to hold captured craft. In the days of the Empire, its bustling bridge would be staffed by the finest crewers in the Imperial starfleet. Its presence in a system mark matters of extreme Imperial import. Though, as is typical of the Empire, not even the Star Destroyer was enough to sate the Imperial hunger for displays of power. Larger vessels, such as the Super Star Destroyer, dwarf even these giants.
Developed by Sienar Fleet Systems for the Empire, the Imperial XX-23 S-Thread Tracer was made specifically to track ships through hyperspace to destination. It was housed in a missle-like shell, allowing the XX-23 S-Thread to be fired at craft from long distances or during chases. The Inquisitor's TIE Advanced fighter was outfitted with the technology, which he used to tag the Ghost starship.
An ambitious Imperial officer, Piett rose through the ranks to captain and was assigned to the Super Star Destroyer Executor, Darth Vader's flagship. There, he chafed at having to serve under the foolish, vainglorious Admiral Ozzel. When Vader strangled Ozzel, Piett was granted a battlefield promotion to admiral -- and given a grisly warning of the penalty for failure. Miraculously, he survived his time as Vader's underling, but died when a Rebel starfighter destroyed the Executor's command bridge.
An admiral in the Republic's service, Yularen served gallantly in the Clone Wars, commanding a Jedi Cruiser in many campaigns against Separatist forces. Yularen was assigned to serve with the Jedi General Anakin Skywalker, and the rigid officer and the impulsive Jedi made for an odd combination. Yularen admired Anakin's bravery and instincts in battle while deploring his recklessness and willingness to interpret orders creatively -- or ignore them altogether.
