PCS Iron Will was an Imperator II-class Star Destroyer acting as the flagship for the renegade Moff Jorgen Sekirol. It had been specially modified per Sekirol's specifications by Kuat Drive Yards, although the reasons at the time were unclear. Some of the improvements included a coordination suite, an advanced HoloNet transceiver, additional EMP-proofing insulation, and a capital-tug-scale tractor beam emitter. With the exception of the tractor beam emitter, all the upgrades seemed rather innocuous in light of Iron Will's employment as a sector flagship. From SW1ki, a Wikia wiki.
