Adar is the first Uruk, a corrupted Elf transformed by Morgoth in the early ages to create the race of Orcs. The Orcs see him as their "father" and follow him as their leader. After Morgoth's defeat, Adar served Sauron, but, disillusioned by Sauron's cruelty toward the Orcs, he turned against him and claimed to have killed him. Devoted to his "children," Adar seeks to create a new world where Orcs can live freely, without persecution.
