Afrasiab (افراسیاب)

Powerful king of Turan and Iran's greatest enemy who waged endless wars against Iran. Afrasiab is the "agent of Ahriman" (evil) who constantly seeks to destroy Iran. Afrasiab is described as being repeatedly defeated by the armies of Iran, with Rostam often leading these forces. Despite marrying his daughter, Farangis, to Siavash, Afrasiab is influenced by his brother Garsivaz, orders the killing of Siavash. Siavash’s murder prompts his son, Key Khosrow (Afrasiab’s own grandson), to launch a massive campaign for vengeance. Key Khosrow beheaded Afrasiab (and Garsivaz) to fulfill the vengeance for his father, mirroring the method by which Siavash was killed.
