Chiming in as 188604's co-GM and co-FM of the Freespacers:
Until Uso started the whole thing on 188604, the planet itself was undiscovered except for the Elysians who had abandoned it as a lost cause. The Freespacers didn't mine it, let alone know it existed.
Freespacers also age faster than normal humans do. A 19 year old Freespacer is physically 39 years old. I'd say kudos on the cougar, but you mention she looks 19.
Furthermore: While it's not necessary a thing you have to do to get approved, I'd like you to have an explanation ready for why she apparently left the Free State so hard it warranted a change of name. You don't have to add it in there; but that is going to come up, and fast.
This is keeping in mind that Freespacers have a networked collective consciousness, and leaving that is a big deal: They can potentially go mad or even die from the sense of isolation. Leaving the Free State is not something done lightly.
