Noctralis, a planet, is the location where Trachta sustained severe injuries during the era of the Clone Wars. In the course of hunting a Jedi Padawan who had turned to the Confederacy of Independent Systems, he and a squad of clone troopers were attacked; the Padawan deployed a thermal detonator, resulting in the clone troopers' deaths and Trachta's injury. The planet was characterized by its darkness and the presence of thin, lifeless trees.
The name Noctralis probably originates from "nocturnal", describing something that is active at night. The planet was initially shown in the third section of Star Wars: Darth Vader and the Ghost Prison, during flashback sequences that depicted the circumstances of Trachta's injuries. The Star Wars: Essential Atlas Online Companion later verified its location within the Expansion Region.
