Glissa, Bosh and Slobad journey deep within Mirrodin's core to confront the insidious Memnarch. With them is the Kaldra avatar—an immensely powerful being of energy summoned when Kaldra's sword, shield, and helm were brought together. With a single spell, Memnarch seizes the avatar and turns it on Glissa and her companions. As rage and despair overcome her, Glissa's body calls forth a great column of green mana from Mirrodin's core, annihilating the avatar in the process. Now that mana hangs overhead in a glowing sphere—the green sun at last, Mirrodin's fifth dawn.
