Demon's Maw (SHIPtember 2015)
EDIT: Runner up for best SHIP!? Thanks everybody!
First spotted by a Terran scout at the edge of charted space, little is known about this strange vessel approaching from another galaxy. The ancient race that built it must be highly advanced, for the explorers were shocked to discover that the ship's energy source is a rapidly-spinning collapsed star, harnessed for immense power. It would seem the "Demon's Maw" is the mothership of a fleet on a long intergalactic voyage.
Approximately 112 Studs long and 50 studs in diameter. Contains two Power Functions XL motors - one for the spinning star and its supports, and one to drive the piston-motion of the three outer engine pods. Lights by Brickstuff.
