Judgment follows the story of Kamahl, who, in keeping truth to his promise made to a dying Chainer, keeps the Mirari safe from others and from himself. Several characters, including Laquatus and Eesha, attempt to obtain the potent orb for themselves; and, Kamahl's sister and mentor, Jeska and Balthor, endeavor to separate the Mirari from Kamahl, for fear of the corrupting influence that the orb has on Kamahl.
