Discovered sometime between the Kymoodon Era and the Rianitus Period, Annoo was under the control of the Hutt Empire as early as the Great Sith War. Remaining under Hutt control for centuries, warfare erupted amongst the native Annoo-dat, leaving the world a barren wasteland. Forced to flee the world, the Annoo-dat adopted space travel and left their homeworld in a mass exodus and conquered neighboring planet Gelefil in 322 BBY.
