She's actually my current larp character. She studies herbalism and healing, and currently holds the position of High Druin (essentially head mage or bishop) in our court. She wears leather armor that allows her to be agile and quiet when slipping through the woods. An example of her typical garb is the green leather tunic I'm wearing in the deviant ID picture, that I sewed myself.
I've definitely got some native american elements, its a fun culture to draw from. Not technically a mage, but can sense magic and can communicate with nature, which sort of counts. Her herbalism is more shamanic apothecary than it is mage-like. It's always interesting to hear about the European larps! I feel like they are way more common there than here in the states.
