The Adamant was a Victory-class Star Destroyer that served within the armada of Grand Admiral Thrawn.
With the return of Grand Admiral Thrawn from the Unknown Regions, only to find that the Galactic Empire, was fragmented as Moffs, Admirals, and Generals became warlords and forged their own splinter groups from the Empire. Thrawn would eventually assemble a large fleet capable enough of threatening the New Republic.
Thrawn dispatched the Adamant to the Abregado system to capture Mara Jade, believing that she would lead him to Talon Karrde, who he wished to deal with for his role in helping Luke Skywalker previously escape Imperial forces. When the Adamant ordered Jade's ship, the Etherway, to dock, Jade surpirsed the crewmember contacting her by demanding to board and speak with Thrawn himself, claiming she had information for him. Taken aback, the crewmember obliged and the Adamant used its tractor beam to land the Etherway in one of its hangars.
