[@Theyra] Apologies for the late response. Yes, that's fine. You have full creative freedom to create whatever backstory you like. Space is vast, and humans are colonized on a multitude of planets both apart of Earth as well as independent. However, if you would like more Lore regarding certain factions hinted at in the OP (IEF: Interstellar Exploration Federation, ExoGenesis) to help brainstorm, then I can happily provide it.
