Avenger
From the Encyclopedia of Speculative Fiction - http://encyclopedia.wizards.pro
The Avenger was an Imperial-class Star Destroyer commanded by Captain Needa. This ship participated in the subjugation of over 436 worlds. It was later reassigned to Death Squadron, and served as the lead attack ship at Hoth. The Avenger unsuccessfully pursued the Millennium Falcon as it fled Hoth, a failure which resulted in Needa's execution by Darth Vader. The Avenger remained with Death Squadron, and served as a communications ship (not to be confused with the much larger Imperial Communications Ship) during the Battle of Endor.
It returned to the Core during the Imperial Civil War and reemerged under the reborn Emperor at the Battle of Mon Calamari. Avenger continued in Palpatine's campaigns under the command of Executor Sedriss during Operation Shadow Hand.
