Actually, who needs a back story for this. It does not need a backstory. The origins can be lost to time. It just needs some legends or fairy tales related to that item. Perhaps the item has the same sort of legend as the Emperor's New Clothing. That way, only foolish players who did not read the campaign's setting packet who would be caught by the item.

If I had created it, I would have it invented by Queen Yocasta's Royal Mage, after he heard that a powerful noble wanted to assassinate the Queen.The noble tried to use it and was cut down on the spot. Go to Comment
