I just finished the Thieves' Guild quests and obtained the Gray Cowl, which is awesome and I'm happy because my character enjoys hunting down artifacts (particularly of the daedric variety) but there's a bit of a problem. I have two books, two keys and a pair of boots that I can not drop, sell, etc. and that... well that bugs me. I like to keep my inventory neat and that's impossible to do with items that never go away. Is there any way to remove them? My computer svcks so I have to endure this nonsense on the Xbox 360.
