Noticing a hideous hand and a slot for a candle, I knew instantly what it was. The Hand of Glory. An artifact made from the hand of an extremely experienced thief. It would allow the holder to sneak past nearly anything as long as the candle remained lit. It only worked once as the candle wax had to be infused with the blood of the user. Tying the user to the magic of the artifact. The artifact would know if someone would try to use it again. If you did try, well.. extreme clumsiness for the rest of your life was just a simple explanation of it.
