Agandaûr's bith date, aswell as most of his personal details, is unknown. He must have started serve Sauron somewhere in the Third Age. Agandaûr became a great warior and sorcerer, likely being taught by Sauron himself.
War of the Ring
At the same time that the Nazgûl were sent to retrieve the One Ring, Agandaûr was sent north to conquer Eriador and destroy Rivendell. He assembled an army in Fornost of Orcs of the Misty Mountains. In Fornost he toke Tharzog, chieftain of the Orcs of Mount Gram, in his service.
Just shortly after the Nazgûl defeated the Rangers at Sarn Ford, Agandaûr met there with the Witch-king. Telling him he finished the preparations and was ready to attack, as assistance in the Hunt of the Ring. The Witch-king ordered him to return and attack immediately.
