Does it come from reading scrolls/spellbooks? Is it intuitively projected through one's mind? Is it drawn from the environment or from some sort of ethereal energy? How does magic occur in your game world, and how/why did you decide on this system? The reason I'm asking is, obviously this becomes an easy question to answer when it is tied to your game's plot, but if the game's plot has nothing to do with the existence of magic, it can become difficult to figure out how magic should be present in the world. At least for me it is. I kind of want a system whereby EVERYONE has the potential to use magic, just that only the most intelligent and most experienced users would be anything beyond inept when it came to practicing it. Any feedback or advice appreciated.
