Knight Hammer
the new name given by Admiral Daala to the Super-class Star Destroyer Night Hammer, originally built by Delvardus. She decided to rename the ship for her attack on the Jedi academy on Yavin 4. The ship arrived shortly after the Jedi Knights had flung Pellaeon's fleet out of the system, but the Knight Hammer was more than a match for the few Jedi on the ground. After the arrival of the Republic fleet, Callista managed to steal a downed TIE Bomber on the surface of Yavin 4. She landed the ship in the fighter bays of the Knight Hammer and set off the bombs stored there. The resulting explosions ripped through the Star Destroyer's engine compartments, leaving the ship dead in space. The gravity of Yavin then grabbed the ship and sucked it into its core. Daala evacuated the crew, and immobilized Callista before escaping in a command-level escape pod.
