Located on the Outer Rim planet of Dalna, West Platt was a city. In 382 BBY, during the event known as the Night of Sorrow, a Jedi transport carrying the Togruta Jedi Master Fliss Woora made a landing at this city. This occurred after Woora's ship picked up a distress signal sent by Jedi Master Creighton Sun, who requested assistance because several Jedi and Galactic Republic guards were being attacked by the Path of the Open Hand cult. Following the transport's arrival in West Platt, the Jedi assembled approximately one hundred Dalnans who were both willing and capable of aiding them in their battle against the Path; three dozen of these Dalnans then boarded Woora's ship. Subsequently, the transport, along with three additional transports filled with Dalnans, departed from the city, heading towards the Path compound. Upon reaching their destination, the Togruta Jedi informed both Sun and Jedi Knight Aida Forte about their stop in West Platt. She also conveyed that, in addition to those who had arrived on her transport, more Dalnans from the city would be arriving in smaller groups.
Lydia Kang mentioned West Platt in her 2023 novel, Cataclysm. This novel was published as part of Phase II of the Star Wars: The High Republic multimedia project.
