At this point, currently there is only one stone that can change its shape into any object. It can't physically be split or made into more than one and will change according to who was the last to touch it.

I was PM'd asking if the supers got their powers because they were hit by the stone, but no: The Paradigm Stone is creating a crazy kind of radiation throughout the city that's creating super powers, allowing scientists to break some laws of physics with their experiments and making magic possible.

I made only one stone, that way there's not three or four crazy powerful characters running around and the other half without. Basically the Paradigm Stone can create a story arc with someone finding it or obtaining it before it gets lost or locked away again.

Edit: Despite the title of the game, I want the game to evolve into a push and pull between our characters and their lives in the city, not just 'who has the stone oh my gawd'.
