A Dark Descent

With the fate of all of Oz hanging in the balance, Glinda struggles to locate a mysterious teacher called Mythra, who is the only one who can guide her in reaching her mystic potential and becoming the powerful Sorceress she is destined to be. While Glinda searches far and wide for her mentor, the fiery-spirited Locasta finds herself undertaking an equally important search for the Elemental Fairy of Lurl, and the means by which to destroy the second Witch, Marada, Wicked Warrior of the North.
