Dragons are born with a small amount of magic to begin with, but it isn't powerful enough to do much at the earlier stages of life. They choose to focus their magic in one particular area so they can become stronger. Later in life they may choose to pick up a second power. This can only happen with the approval of the Kouryuu council and Lady Hjördis.
