Spirit Stone

A Spirit Stone is an Amazonian sacred object used by witches to trap spirits or demons.

One such stone was used to trap the demon, Athulak. To make sure no one could release the demon by praying with it in their hands, the witch buried the stone. Unfortunately, it was dug up three thousand years later and fell into Stephen Tremaine's possession. He made an accidental wish while holding the stone in his hands, and unwittingly released the demon from its confinement.
