Bearing in mind that we never actually meet Baron Harkyn during the game, has he fled or been killed by creatures when they overran the city or was he in league with Mangar?
I was always under the impression that he was on vacation somewhere a lot warmer than a city locked under eternal winter.
You know, if I remember how to do it, I could edit a 4th (and maybe 5th) level into Harkyn's Castle that has the baron cowering in the closet or something...
