[@PlatinumSkink] Personally I suggest having the character's backstory prepared, but kept to yourself. Because a character's history is a large reason for their personality and motivations. It would be a good way of keeping your character's actions consistent with the way they've dealt with their experiences and whatever their current agenda is (other than not getting killed by the Alliance, since I'm guessing they were brought along on this crew against their will because of their criminal record :lol)
