The Drej Mothership, also known by it's original "Alahenena" ("planet killer" in the Drej dialect), is a massive alien mothership constructed and used by the sinister blue pure energy-based extraterrestrials called the Drej. This incredible warship designed with Drej technology can fire laser beams capable of annihilating entire planets by firing at them, causing each planet to spin faster and faster, until centrifugal force overpowers gravity, thus causing those worlds to fly apart at the seams.
