Niango was a city situated on the planet Felucia. In the final days of the Clone Wars, a mission was led by Jedi General Aayla Secura to destroy a Separatist biomolecule facility situated in the city. This facility was spreading a toxin into the planet's water supply. Secura, along with Barriss Offee and their Padawans, attempted to stop the poison from spreading with the help of CC-5052 and the 327th Star Corps. After the execution of Order 66, the newly-formed Galactic Empire finished the job.
