Aantooine

Aantooine was a planet founded by two races that split into a struggle of two galactic empires. The Aan race were a devoted people with considerably higher status than their lesser counterparts, the Tooins. Over time, the Tooins begged for the same amenities as the Aan, but were denied. The Tooins formed a new world army called the Tooin Clash Force which temporarily seized control of Aantooine's capital Antoo, before being defeated by reinforcements.

This new war then became interstellar, with each new world colonized by either side retaining a mark of their presence. As the Aan pushed toward the core of the Galaxy, they came across such worlds as Alderaan and Taloraan, and Manaan. The Tooins took control of what later became the Outer Rim Territories, founding such worlds as Tatooine, Dantooine, Klatooine, and Mantooine.

The war ended when another species intervened and destroyed both empires and their subsequent civilizations.
