Q-Ships
Q-Ships are ring-shaped inter-stellar space-ships originally developed by the OGC Technologies for travel between the planets of the Outer Rim. They fell out of popularily due to their use in the invasion of Zen-Whoberi, and are now used primarily by Thanos and the Black Order.
The design of the ships draws heavily on Korbinite technology, using magnetic warp engines to achieve faster than light travel.
