Filnjar is the target for Hafjorg's delivery to Shor's Stone.
It is possible for Farkas may ask the Dragonborn to intimidate Filnjar by starting a fist fight with him to teach him a lesson, until he yields to them.
Odfel: "You think living with Grogmar is easy? Did you see how he lives?"
Filnjar: "You two will just have to learn how to get along until we can build you another house."
Odfel: "At this rate that'll never happen."
Filnjar: "Quit your bellyaching. We've all got our problems."
Grogmar: "I've been cracking rock ever since I've been able to hold a pickaxe and I'm telling you, this mine is drying up."
Filnjar: "And I'm telling you, you're wrong."
Grogmar: "What makes you so sure? What if I'm right?"
Filnjar: "I know there's ore still in there, I can smell it. You think you're right, you can pack up and leave any time you like."
- If Filnjar killed by after completing "Mine or Yours," the Dragonborn will receive a Letter of Inheritance via courier, along with 100 .
