The Amulet was made and used by a vampire named Trax in 1943, and Trax used it to kill witches. It was then passed down to his son Shaks who he used it for the same purpose. The Amulet has silver markings and intails and in the middle is an emerald jewel which is where the magic comes from. The Amulets powers only work for vampires, Trax made it that way so if nything was to happen to him or to his son no-one else could use it. It is still unkown how Trax made it with magic since he is a non magical being, mabie he drained the powers of the witches he killed or got one of them to do it.
