End Of Rules

You couldn't do just anything with magic, the rules existed for a reason.

Some, even non-users knew. No creation without equal destruction. Dwarves Grown Gems don't work for magic. Only what was possible should be recreated.

The full list was very long, but the point was, even at a snap of the fingers, you still had to be reasonable.

Because ignoring the rules was possible, but only at the expense of huge amounts of magic. And most users had very little to begin with.

Until someone worked out how to make more magic from a spell within the rules, technically.
