Sten's epilogue text when my very first warden made the Ultimate Sacrifice is one of the few instances that I was truly saddened in a game:
"Sten bowed once before the Warden's remains and then left without saying a word...When fellow Qunari asked if there were worthy people outside of Par Vallon Sten answered that in all his travels he had only met a single one."
When I first met Sten I really didn't like him for all the obvious reasons but little by little he grew on me and by the time I'd finished the game he had become one of my all time favorite characters in a game, or anything for that matter.
