I totally have an idea for a character for this :D Essentially human too, just of a subrace that's become quite used to living in low or zero gravity- They're a good deal taller than normal humans, and not as physically strong, but when it comes to moving around in less than 1G environments, they tend to be a lot more nimble.

What kinda tech level are we generally looking at for this? Like, what are some examples of what would currently be considered high tech, and some examples of stuff that people might just see every day?
