Mark is a darkness bender. he lives in a world where there are 3 elements, fire, water, and earth. But there's two more, light and darkness, that nobody knows about. Fire beats earth, earth beats water, and water beats fire. Fire benders are very energetic and messy. Water benders are neat and calm, and earth benders are somewhere in between. Mark towers above every element and is very rude. He can curse people and turn into a shadow.
