WWE designed this Undertaker amulet for several reasons. It could server storyline purposes in the same way as the urn did, it could look intriguing on Undertaker, and it could be turned into lines of merchandise. They went through several designs as you can see, developing a back story of Egyptian god and the druids bringing it to The Undertaker. But that's as far as the concept went, the amulet ended up being one of the WWF's dropped storylines.
