The Interrogator was an Imperial II-class Star Destroyer under the command of High Inquisitor Antinnis Tremayne. Captain Jovan Vharing was captain of the ship shortly after the Battle of Hoth, although his command did not last long. The Interrogator was responsible for the bombing of a settlement on Qlothos that took the life of a prominent engineer from Kuat Drive Yards, including his family.
