i'm not really a fan of the "your character chooses to come to the game on their own" approach just because for a lot of my characters there isn't really a good canon point for that, but i do think that would work better than the character just waking up in the middle of russia. maybe they found an old vex gate and accidentally reactivated it somehow?

like i said tho i'd probably app regardless of whoever ran the game decided to do.
