Wild Magic
Your innate magic comes from the forces of chaos that underlie the order of creation. You might have endured exposure to raw magic, perhaps through a planar portal leading to Limbo, the Elemental Planes, or the Far Realm. Perhaps you were blessed by a fey being or marked by a demon. Or your magic could be a fluke of your birth, with no apparent cause. However it came to be, this magic churns within you, waiting for any outlet.
