Hello, and welcome! I have two characters, ordhan and demetir. Demetir is a young surface dwarf, so the chances of him having met your character are slim.
Ordhan, on the other hand, is a knight of Denerim who has lived in the city for the past twenty years. Though he's not the most sociable sort, there's the chance that their paths may have crossed at some time or another. I'd be up for working something out!
