Psionicist: Phenomenon

"George Malley is an ordinary man, who is about to become ... extraordinary."

This horse is probably long-buried, but I keep coming back to the idea that Psionicists are just ordinary people, who somehow find themselves with a special gift (or curse). In the case of the character, George Malley, played by John Travolta in the movie Phenomenon, that special power is telekenesis, along with some other interesting powers.

Telekenesis, Firestarter, Precognition and Invisibility are four of the 10-12 "wild talents" that i'm thinking Psionicists might start with. I'm picking away at other ideas for talents, and am always open to suggestions.

I'm still trying to work out the way that Psionicists improve their wild talent, and gain new talents. It seems obvious (at least to me!) that gaining those talents should follow level-progression, but how to keep a Psionicist balanced against the Magic-User and Cleric (the other two "casters") but still give the Psionicist class its own "flavour", is the challenge I am currently wrestling with.
