Sar-Aggreth was one of The Seven Disciples of Sar-Elam, and a powerful wizard. Along with Sar-Issus and Sar-Shazzar, Sar-Aggreth founded the first of the Seven Cities. He was also the headmaster of the first Academy of Magic, where he was remembered as a good, if somewhat strict, teacher. Sar-Aggreth wrote the first essays on the nature of djinns and the spirit world.
