Because of a discussion on Dragon Age Origins that lead into another discussion about how your custom character is shown to have something of their own personality, I've been wondering if there will be a prologue that establishes your character based on the origin/traits you've chosen leading up to your capture. à la DA:O though much more abbreviated, I'd even be fine with something text only.
The history of the origin characters seems like it's already a large part of their stories, has Larian mentioned definitively if they'll deal at all with your custom character's history?
