The Tatooine-Geonosis war (also known as the Arkanis War) was a major conflict that took place between the Tatooine of Fourth League Kingdom and the Imperial Geonosia (formed from the Duchy of Geonosis , which was showing an imperial attitude). The war lasted 40 years, and claimed the lives of over 200 Million beings on both sides. The war was supposedly localized to the Arkanis sector, but spread as as far away from Tatooine/Geonosis as Ryloth .
