Possessed Witch of the North (Water)

Lore
For the first time ever, the Witch of the North utilized her dark side, seeking the source of the massive magical power that lies beneath the Emerald City. After losing to the Wizard of Oz, she now spends her time in her dominion teaching children magic. And even now, she still has forgiven herself for losing to Oz. "If there is a will to use magic, you must find a way."
