A giant, 30-kilometer-long saucer-shaped mothership built by the Cardianon. A city exists in the center of the saucer, but only a tiny population lives there; half of the Cardianon population are in a state of coldsleep. Invasion from outside is nearly impossible, thanks in part to the drone fighters that launch from the mothership and intercept incoming attacks. The ship is also known to occasionally seize spacecraft with its tractor beam for reasons unknown.
