Agoro was a respected Valderon until he started to disagree with the teachings of the Valderon people. He was then banished from the Valderons, but he managed to acquire a following and many became followers of him. He eventually takes a trip through time and steals information from the future to build flying machines. He uses those machines to start a war against the Valderons, namely the ruler El Hanuri. Eventually Merlin sends all of the flying machines away, and Agoro is forced to live in peace with his Valderon brothers.
