Peremptory

An Imperial Star Destroyer that served in Grand Admiral Thrawn's personal armada.

The massive ship was lost after New Republic agents deliberately rammed a slave-rigged Dreadnought into the vessel.

The Peremptory was lost with all hands, including the entire command staff and bridge crew.

Later, Captain Brandei of the Imperial Star Destroyer [Judicator] vowed to himself that he would avenge the loss of the Peremptory. Brandei was personally rebuked by Grand Admiral Thrawn, who said that the New Republic would eventually face the consequences for their destruction of the Peremptory.
