The Wise King who rules the land of Uruk in ancient Mesopotamia, having returned from his journey for immortality after the death of his dear friend Enkidu. Legend speaks of him as "The One Who Saw Everything." He leads his people with strictness, sometimes cold, yet acknowledging human emotion. In a sense, he is the form of Child Gil grown up correctly, though his speech and conduct remain unchanged. Ishtar claims he is simply "toggling a switch." Though he rarely shows it, he still avoids going to the Cedar Forest, suggesting Enkidu's death still weighs heavily on him. First person: I (Ore - arrogant, kingly) Second person: Mongrel / (By name once recognized as a worthy human) The supreme Wise King returned from his quest for immortality. A great King of Uruk who leads his people with a mix of ruthlessness and humanity. Due to the Three Goddess Alliance appearing in Uruk because of the Incineration of Humanity, he determined that fighting as the Hero King would lead to Uruk's destruction; thus, he devotes himself to being a mage to ensure the nation's prosperity (though he calls it "mere imitation"). He is overworked to the point of potential death by exhaustion. Arrogant, self-centered, and audacious.
