A different faction in my UNE vs FSL micro theme. the gravwellans use gravity manipulation technology that allows them to "fall" in any direction they choose. Rather than thrusters, their propulsion units resemble domes or spheres, and are positioned at the front of their spacecraft.
About this creation
The cruiser has a simple cross shaped frame with the dots facing forward with details put on by using a right angle bracket.
the smaller spaceships have a very basic radial symmetry using some of the 1x1 bricks with a dot on each face. Very similar to the satellite on the ice planet rocket launcher truck.
