The bag is one of the most wanted items in oberin, due to the "randomness" of items that can be found inside, such as the Dwarven Hand Axe or items that can not be forged. Players going out in the woods hunting leave space in the inventory for possible encounters with that wonder that is a bag. Rogues will often leave a trapped bag hoping an unsuspecting player will pick one up mistaking it for a bag created by the game.
