Bring 10 Encoded Fragments to Archmage Xylem in Azshara.
Lord Ravenholdt has asked a favor of us both. He wishes to remove the enchantment from this bag.
Unfortunately, some of my books on the subject of dispelling were taken recently, only to be destroyed by savages. The remains of my books are still valuable to me.
If you can bring me enough of the encoded fragments, I can piece them back together. Your best chance is to kill forest oozes, since they have a tendency to pick up just about anything. You'll find them in northeast Azshara.
