Zelena

Zelena, better known as the Good Witch of the West is one of the four Witches of Oz. Her element of magic is innocence. She was the latest member to join the witches.

Background
She grew up with an abusive adoptive father in the West, after he told her about her heritage Zelena's questions were answered by the Wizard of Oz who showed her her birth mother, Cora, giving her baby away to a cyclone leading her to Oz. She also learned about her two year younger half sister Regina who did have a wonderful youth. Zelena instantly grew green with envy but Glinda took all her fear and envy away by making her witch of the west. It made her feel wanted at last.

As Witch
Zelena did her best and soon became a respectable member of the witches. She learned after a week that she was more powerful then all the other witches combined. Her innocence was proved when she still let Glinda be in charge.
