After playing Destiny 1 and 2 for over a decade if not more I've come to realize that we know absolutely nothing about our own character. I mean throughout Destiny 1 and 2 we've basically learned all about pretty much all the characters in the game enemies and allies cause in the seasons and dlc's we end up delving into their past but throughout this franchises life the one person's past/history we've never delve into is our own, I mean all we really know when Ghost turned us into a "Guardian" in the Cosmodrome is that he'd been looking for us for a long time and that for some reasons we met some unknown conditions to be reborn. Honestly our character is probably the last and greatest mystery in the game.
