So, we would play characters with powers directly based off of the properties of the Chemical Elements, like Hydrogen, Mercury, Uranium, etc. Figuring out what to do with their abilities in this world. It would take place in the modern era, with characters from any walk of life, now finding themselves either coming to terms with long time abilities or discovering new ones.

This sounds pretty interesting.
What would the abilities be limited to?  I mean, I get the idea their based on chemical elements, but does that mean the abilities are only those that have some sort of relationship to their physical properties, or would esoteric powers be allowed too?
