The Stalwart over NL-1.
From the bridge of the Stalwart, Thrawn supervised the construction of the space station NL-1 in the Pakuuni system during the Battle on the Frontier. It would also serve as the base-of-operations for actions against the Pakuuni Pirates and Rebels who threatened the station, success in no small part due to the actions of ace pilot Maarek Stele.
Following the completion of NL-1, the elimination of the Pakuuni Pirates, Thrawn changed his flag from the Stalwart to the Imperial I-class Star Destroyer Vanguard.
