Just a point of order, but are there any Grey Wardens in our group who... would really care what the chantry has to say?
Like, if the Revered Mother told us to take a Templar, I have my doubts that the mage who was labeled an apostate that's the mission commander would be down with that., I dunno how Lalin feels about the chantry, but Conlan is slowly developing the belief that the Maker has a personal grudge against him and unless Falina secretly went to Brother Burkles (possibly existant) chantry...
I had the thought yesterday that Simon is investigating the Tevinter slaver. Not usual Templar work, but I figure it's kind of like Ser Otto investigating the Alienage. It's entirely what a Templar would do, I know. But it gives us less sidequests to deal with, and afterwards we can go "Hey a Templar would be a good thing to bring along. ya know, for darkspawn mages."
