Merinita

You are not actually a magus, but a spirit of the earth itself - you are taking the form of a witch for this conference. You watch over things which miht help or harm the world as a whole, and this is one of them. Magi's continual harvesting of raw magic (vis) could slowly destroy the earth - worse still is the prospet of magicians working with the fae creatures.
Magically - the earth bends to your will - the air and it's moods are your main tools.
