Create yourself a race and get in space!

What I want to do, is create some Space Cannon for the Vine; naturally the Canon for Space will be completely unrelated to that of Earth. (Unless let's say someone tries to invade Earth). So I'm here to ask people to create races, cultures, way of life. Planets anything to help this get started. I do ask that you don't over power space with a whole bunch of superheroes.
