Noctralis

Noctralis was a planet where Trachta was grievoulsy injured during the Clone Wars. He and a group of Clone troopers were hunting a Jedi Padawan who defected to the Confederacy of Independent Systems, when the padawan threw a Thermal detonator killing the troopers and injuring Trachta. The planet was dark and had spindly looking dead trees.

Behind the Scenes
Noctralis likely derives it's name from Nocturnal, which means active at night, and a fitting description for the dark shrouded planet.
