Derra IV, often shortened to just Derra, was a celestial body situated within the Expansion Region of the galaxy. In the time of the High Republic Era, it was the location of the Derra Outpost, overseen by Jedi Master Tera Sinube in 231 BBY. Due to its proximity to the Mid Rim planet Cyclor, Derra was called upon for aid when the Nihil launched an assault on the Cyclor Shipyards. In response, Sinube dispatched a Drift of Jedi Vectors, with Master Porter Engle in command.
