1) In
Dungeons and Dragons, Spellfire is raw
magical energy which is not being chanelled through a
spell. It has the capacity to burn fiercely and, in some cases, to heal. Few individuals have ever been able to wield spellfire, though all of the chosen of
Mystra (goddess of
magic in the
Forgotten Realms setting) have been imbued with the ability to use it.
2) A novel by
Ed Greenwood, the creator of the Forgotten Realms game setting. The main character is a girl who has the ability to absorb magical energy and wield it to burn or heal. It has lots of good bits with
Elminster.
3) An out-of-print
CCG published by TSR based in the Dungeons and Dragons universe. While the game is often frowned upon by gamers, it was successful enough to warrant nearly a dozen expansions. The rule system is simple and lacks proper balance, has terrible art, but has cards for almost everything ever published in the system, making it a neat collectible.
