Stand Ability

It follows the law of equivalent exchange, sacrificing one thing of equal value to gain another of equal value. For example if you wanted to revive someone, you would have to sacrifice someone else.

Backstory
Though no one is exactly sure when, at some point during the ancient history of stand users in Italy a stand was imbued into a golden pendant. This pendant gained the power to alter the very fabric of fate and shift the very essence of reality should it be requested to do so, though it always charged a high price for this. In the 1700s a rich noble man living in the British Colonies in North America tracked down this item and brought it to New York in the hopes of saving his sick and dying wife. However upon learning the price to do so would be his own life he instead buried the item away inside his families catacombs which lay beneath their property. Eventually when the man died he donated the land, and it was eventually repurposed into a school, named the Granville Payne Academy.
