The second Invid Invasion
The Orion is an old transport space vessel built during the early years of the Southern Cross. It’s main engines are powered by protoculture and it has minimal weapon systems. It can hover stationary and maneuver by it’s anti-gravity drives but it’s main speed comes from the giant reaction thrust boosters on the rear of the ship. Top speed is mach 5 in atmosphere and double in space.
(There is an image of the Orion in the map section if you want a better look at it.)
