Jokul Frosti

Jack Frost is the oldest spirit of them all. He is also the only child. Both King and Prince of Winter for longer than time itself, Jack allowed another Winter elemental to take kingship as he became Prince Jokul for millennia and also herald in the 1600s, being called Jack Frost. All of the winter spirits and sprites knew him and loved him as their frozen hearts could. He was forever a child, something almost all of the other seasons and spirits/sprites forgot.
