I'm thinking of making an RP that takes place in the future where humans have had to evacuate the Earth, and colonize another world.
Our characters would be members of "Zion Colony" with varying occupations (medic, security, engineer, scientist, pilot, ect), and would be tasked with maintaining and protecting it, while occasionally going on "expeditions" to places outside the colony.
Characters could be human, alien, or androids, also.
