Admonitor

The Admonitor was an Imperial-class Star Destroyer under the command of Dagon Niriz. When Grand Admiral Thrawn was assigned to the Unknown Regions, it was this ship which he departed on; his longtime associate, Voss Parck, was assigned as the ship's first officer.

One of the Admonitor's first encounters on this mission was with Ebruchi pirates, which Thrawn was able to deal with effectively.

Later, the Admonitor returned briefly to the Galactic Empire so Thrawn could assist Darth Vader in the removal of Zekka Thyne, and thus Black Sun's influence, from Corellia.
