Abo, the star of the system, was feeding the Star Forge, built by the Rakata and placed close to the sun. The system afterward became part of the Galactic Republic. Following the Battle of Rakata Prime, the wreckage of the Star Forge and the vessels lost during the battle made the system difficult to navigate. After the Jedi Civil War, the Republic made the entire Lehon system a protected historical site and dictated that it was not to be entered without permission. This lasted until the Republic Dark Age, when the crumbling government could no longer protect the location.
