The Kethor was a Mere cruiser commanded by Captain Orsai prior to the Clone Wars. The Kethor participated in The Battle of Nod Kartha led by Nym, alongside her sister ship, Tritus. Upon reversion from hyperspace, the Kethor was hit by fire from the orbital defenses around Nod Kartha, and sustained critical damage. The crew bailed in escape pods, but Captain Orsai remained onboard to plot a collision course with the nearest of the two shield generators protecting the planet. The Kethor rammed the generator, and the resultant explosion destroyed both—allowing Nym's forces to reach the planet's surface.
