The Darkhawk, a freighter originally utilized by the Separatist faction, underwent significant modification to serve the 1st Legion. This elite Imperial stormtrooper unit, acting as the personal force of the Sith Lord Darth Vader, employed the vessel.
During the conflict between the Empire and the bellicose Grysk, it fulfilled the role of a boarding craft against enemy starships.
Originally, the Darkhawk functioned as a freighter for the Confederacy of Independent Systems. Following the fall of the Republic and the conclusion of the Clone Wars, the First Legion, the legion under the direct command of the Dark Lord of the Sith Darth Vader, retrofitted and altered the vessel.
Emperor Palpatine, sensing a disturbance in the Force, dispatched Vader and Chiss Grand Admiral Thrawn to Batuu, specifically instructing Vader to bring the Darkhawk and the First Legion along.
On their journey, Rukh, Thrawn's personal assassin, repeatedly infiltrated the Darkhawk utilizing his cloaking device out of sheer curiosity. Commander Kimmund issued a warning to Rukh, stating that any further such actions would result in him being shot and killed.
