Seledra-Zin was a refugee aid worker (of the female persuasion) stationed on Clak'dor VII, who developed a romantic relationship with Sander Delvardus, the captain commanding the Star Destroyer known as the Brilliant. It is said that during a heated dispute, he used a dynamic hammer to strike her, causing her to fall into a comatose state. Overcome with grief, he dedicated several years to attempting to revive her from this coma, and he placed her within a suspended-animation casket. This casket was initially installed in his private living space on the Brilliant, and later on the Night Hammer. Following Delvardus's demise, brought about by Natasi Daala at Tsoss Beacon, Daala, in a strange turn of events, seized control of the Star Dreadnought, renamed it the Knight Hammer, and directed it towards the Jedi. Unbeknownst to her, Seledra was located in a chamber at the ship's foremost section. After the failure of the Assault on Yavin 4, Seledra met her end when the Knight Hammer was destroyed within the atmosphere of the gas giant Yavin Prime.
