Hey there, I'm Justin, but I go by Conlan, since he's my char. (That's right I only have one.) And I also welcome you to the game.
Conlan was a mercenary who spent his days in and out of Denerim for the past... well 30 years or so. If Cyrill's weapon repairs are anywhere near affordable, then Conlan would probably be in his shop after just about every mission.
