The Elements
These are the most powerful and mastered of all elements. There is always and only one in the world at any given time. Typically, because they are so powerful, the elements do not live long and sometimes meet dangerous ends. The Elements pass down from generation to generation, only wandering either once in a great while or when the generation ends. Not one is more powerful than the other, and history dictates that if they fight each other, destruction will ensue.
