Prior to the Clone Wars, the Colicoids acquired Axion, a planet which was previously a Human colony. Subsequently, it functioned as a research and development hub for the Confederacy of Independent Systems. In 22 BBY, specifically four months following the First Battle of Geonosis, the Battle of Axion occurred on this world. Sometime after that conflict, Reginald Barkbone, a pirate, made his escape from the Imperial Royal Guards amidst the chaos of a limpet mine explosion, which he had affixed to a power droid.
