Andurax

The Andurax was a spacecraft operated by the "galactic caretakers" known as the Apocalypse Monks (TV: The Return of Doctor Mysterio) or the Vigilant Eremites. Using all four gemstones, the Andurax was able to siphon excess dark energy from the main universe into an uninhabited one through the Nether Gate of Tersimmon. (COMIC: Ghost Stories)
