Kyloth's Amulet

Kyloth is a dragon who is the father of four elemental dragons, a fire dragon, an ice dragon, a nature dragon, and a thunder dragon. Before his children were born, there was an amulet. An amulet that he had worn around his neck for centuries. He was the only one who knew what the amulet could do, and, knowing that the power was too great to have it fall into the wrong hands, he never told anyone what it could do. But, instead of preventing catastrophe, it led to catastrophe, and a war against the shadow serpents began. Once his children were born, Kyloth had them create a land, each one corresponding with the element that they controlled. Then he broke the amulet into four pieces, and each of his children took a piece, hiding it in their land and doing whatever it took to keep them hidden. But they are still young, and do not know how to control the elements well yet. Will they be able to protect the amulet pieces, or will they crumble under the weight of war?
