[4] Karyan is the setting of a Zoroastrian legend during the time of the Muslim conquest of Persia, where a Muslim force of 12,000 men besieged Karyan only to be slain single-handedly and unopposed by a Persian defender named Shah Karan while they were engaged in their prayer.

[8] However, a new Muslim army, seeking revenge, was able to conquer Karyan after the betrayal of Shah Karan's wife and the residents were then massacred.
