Drake in The Haunted Edit
Drake finds this along with Diamond Boots and a Diamond Helmet in a makeshift home. After he and Grayson looted the chest where it was found, Drake puts this in his backpack, which was left behind in the fight at the Magic Library. This is speculated to have been destroyed in the library's destruction.
