Har Gau was a city situated on Felucia, established by the Gossam settlers there. It was home to the many water stations that a toxin was spreading to. Aayla Secura, Barriss Offee, and their Padawans attempted to stop the poison from spreading there. With the execution of Order 66 and the Jedi's deaths, the newly formed Galactic Empire finished the job of stopping the poisons' spread.
