Artifact

You were unremarkable. However, things changed when you came into possession of a seemly mundane item. At first, it was just a vague feeling that there was something special about it, but over time you realized it must be bestowing you with supernatural abilities. Where it came from and who made it might remain a mystery to you. Who can know the story of the secondhand necklace or how many hands have held a wayward coin lost to the universe?
