Troxar, the homeworld of the Troxan species, existed as a planet in the Expansion Region's Troxar system.
In the time of the Clone Wars, Troxar aligned itself with the Confederacy of Independent Systems. As the Galactic Republic launched an invasion of the planet, the Troxans pleaded with Count Dooku for assistance. Dooku pledged to send reinforcements and instructed the representatives to continue fighting for as long as they could; however, he ultimately left them to be destroyed while exploiting their resistance to occupy Republic troops.
