creative time

OK here is a random thing that you create for fun i will try to post these kind of questions a couple times a month
You must chose an object. It doesn't matter what it is as long as its inanimate. It has to be wanted on good and evil sides for a specific reason. It must have supernatural powers.
Ex:
a Fae rock. it was created by fairy's as a source of all their magic. both sides want it to harness its power and use it against the other side.

be as crazy as you want but follow the rules. one..... two....... CREATE!
