Blinded by his obsession, he submits himself to another master to right the wrongs he witnessed in his life. At his new master's command, Nathaniel hatches a plan that begins in murder and leaves King Rohn half mad and suspicious of his brother-in-law. As Nathaniel bends his will to vengeance and sorcery, an old friend must become his enemy to save the sister kingdoms and thwart his plans. What hope is left that will save the sister kingdoms from Nathaniel and his dark master?
