Magic

In her new world of discovery, this woman, named Rose Green, became aware that she had Magic, like good old storybook Magic. Now that her inner dragon was awake, she realized that all dragons are magic, a part of their own energy is magic. But since Magic is part of their life energy, like physical energy, you cannot use too much of it, or you will be tired and will need rest to recover.
Rose soon found out that in her eager use of Magic, especially at the begining, she sometimes overdid it and a couple of times literally collapsed. In order to get the best possible results, you have to practice Magic to learn how to do it well. Like it has been said before practice makes perfect!
