How much magic lies about in the land?
There are no magical creatures like dragons or gryphons, and no people except humans. But there is a spell, a major spell, that is vital to the kingdom. There is also a wise old woman who does some stuff in a secret place.
Though -- its use in battle is important. Especially since it's a question of why rebel forces can stand against the queen if the major spell fuels her armies.
Hmmm -- kings and queens might have to send their armies from their kingdoms. So battle magic, at least, is probably distinct. If existent.
