Well, that wasn't choice, I couldn't go to mages so I've gone to the templars :D So, yes, if that's what you thought (I'm not sure, this quest was weird...) Why, is part with this music close? :D Right now I found Skyhold :)
Well yeah that's what I mean, if you chose to side with Templars or Mages lol But no, since you chose Templars I don't think you will hear it unless it's in another part of the game as well. This soundtrack was from a cutscene in the Mage choice storyline.
