This also varies from the game — it is the version of the game I was playing in my head while playing Valorien. Oddly, I seemed rather in tune with the game and foreshadowing events in it. Though at times, I had to make up stuff I did not know — for example, how King Maric died. Therefore, expect that it might stray from iron-bound Dragon Age canon, and take that with a grain of salt.
