Ironhand was a part of the Imperial Remnant's Starfleet, specifically an Imperial-class Star Destroyer, that operated at least fifteen years following the Battle of Endor. It was one of the four Star Destroyers from the Braxant Sector Fleet—along with the Relentless, the Tyrannic, and the Obliterator—that swore loyalty to a resurrected Grand Admiral Thrawn, who was actually a fraudster named Flim, and was under the command of Captain Argona. The Ironhand's purpose was to take advantage of the Caamas Document Crisis to instigate internal strife inside the New Republic, by igniting a war concerning the Bothan home planet of Bothawui. The Ironhand was equipped with a cloaking device for this operation; however, the scheme failed, and the Star Destroyers received orders to withdraw.
