First off, I am the first NS. I did not see any power guidelines. I assumed other nations would be of similar power.
Also, most 'villas' are grouped into villages of maybe 100, forming space villages that are somewhat clustered to form 10 major space-cities. They need the space being that one life can control 50 bodies.They're sentient population is about 10% of humans, but that still means a lot of bodies. That is roughly 5 times earth's population, although evolutionary advantages allow them to be fairly compact. My NS is still very much WIP.
