Fury can be defeated fairly easily, though not through combat. He has a Oblivion style Gray Prince esque weakness, though I'm not sure Skallagrim remembers the steps he took so long ago to actually do it. I might remind him when the fight comes about, if it ever does.
Fury might make an appearance at the Hq later on, I'd like to finish the fight with Kanitah first, though that could lead to a slightly weird situation when he runs into him in the dining hall.
