I've started slaying dragons (like all good Dohvakiin must), and with each beastie I down, I'm getting close to 200 lbs of loot, mostly in the form of Dragon Bones and Scales. These two items are high weight, and high value, but I can't seem to find any actual use for them, especially since most of the shopkeepers I talk to aren't interested in purchasing them.
Are these just supposed to be for decorating one's house? Or is there some nefarious purpose for them down the road that I should stockpile them for?
