As the Clone Wars raged throughout the galaxy beginning in 22 BBY, the Magnus, or ruler, of the planet O'reen and its people faced the threat of invasion when a military exploration ship from the Galactic Republic stumbled upon O'reen while searching for Confederacy of Independent Systems supply outposts. When the O'reenians took the crew prisoner and enslaved them, the Jedi General Morningfire came to mount a rescue along with the clone troopers of Vornskr Company. The Magnus ordered the O'reenian military to resist the invaders, but during the ensuing conflict, the leader was killed. The ruler was succeeded by another Magnus.
