Prometheus was a Greek Titan. Possibly one of the most important Titans, as he stole fire from Zeus and gave it to the humans. This system was developed to resist those forces through technological means.
A long time ago. Final fantasy III came out with a new approach to learing magic. The characters would be equipped with espers(magical beings) and as they fought more battles, they would learn spells from the espers. What if a similar approach to learning magic was applied to a P&P rpg?
