I've been recently thinking about what had really happened at the end of the campaign. I will not write about speculations on elven pantheon, Blights and so, but what had inspired me - and I was not thinking about this soon after finishing the game - is:
Flemeth has released the soul, probably of the Old God, to the Fade. The same area, where soul of Corypheus was sent. Not to mention that there is mortal Grey Warden/ Hawke. I wonder, if this may cause some strange connection about them. I am curious if these souls could possess body of those, who had remained in the Fade. Maybe this kind of connection with and Old God soul could somehow save of dying those, who stayed there?
At what cost, this is another question. I wouldn't like to see for example Loghain returning from the Fade with the soul of Old God and/or Corypheus. I hope, that "Logheus" as I would name him won't return at this form. Not only Loghain could be possesed by the souls there, but I wonder if that could be possible.
Seriously, I wouldn't like to face once again someone possesed by Corypheus or Old God in nearby future. But the thought about souls of Old God and Corypheus sent by Flemeth and Inquisitor almost at the same time is somethink to think about. I don't know however, if someone else already thought about this. Probably yes, but there are so much posts about different theories...
