The Mission to Radnor took place in 27 BBY. Following an accidental leak of deadly toxins into the atmosphere of the planet Radnor, the Jedi Council (at the request of the Galactic Senate) sent four Jedi―Obi-Wan Kenobi, Siri Tachi, Soara Antana, Ry-Gaul, and their Padawans (Anakin Skywalker, Ferus Olin, Darra Thel-Tanis, and Tru Veld, respectively)―to aid in the evacuation of the surviving populace from the Twin Cities, Aubendo and Tacto.
