As the sun crested the mountain heights, casting rubies of crimson light across the streams, Rostam gathered the vast spoils of war and distributed them among his brave warriors. With the thunderous call of war-horns echoing through the sky, the World-Champion set his host in motion, marching straight toward the realm of Afrasiab, their eyes wet with tears for Siyavash and their hearts consumed by vengeance.
When news of Rostam's unstoppable advance reached Afrasiab, the Turanian king turned in panic to Piran Viseh, lamenting that the Iranians had bound their loins to eradicate Turan. Afrasiab sought to capture Siyavash's young son (Kay Khosrow) and mother to send them back to Iran as a bid for peace, but fear overtook him. Ere Rostam reached his doors, Afrasiab abandoned his royal throne at Gang-Dezh and retreated with his armies toward the Sea of Chin.
Rostam triumphantly ascended Afrasiab's majestic throne, casting the king's fortune into the dust. He recalled ancient wisdom—that an enemy must not be spared, and that evil must be uprooted. He ordered the vast treasures of Turan unlocked: hoards of gold dinars, radiant gems, ivory thrones, brocades, and noble steeds. Rostam bestowed the ivory throne and the governance of Chach upon Tus, commanding him to execute any who dared speak Afrasiab's name. To the wise Goudarz, he granted Sepijab and Soghd, praising his lineage and sagacity. To Fariborz, Siyavash's brother, Rostam sent a golden crown and treasure, exhorting him to gird his loins tightly for his brother's blood and forego sleep until Turan was broken.
News of Rostam occupying the throne reached as far as Chin and Machin, prompting local lords to arrive with lavish tribute; Rostam granted them amnesty. For a long duration, Rostam remained in Turan, spending his days hunting. One day, his brother Zavareh reached a lush grove that had once been Siyavash's favored hunting ground. Upon hearing a guide recount how happy Siyavash had been in that place, Zavareh collapsed from his horse in grief. Awakening, he swore never to rest or hunt for pleasure until Turan was utterly laid waste. Moved by Zavareh's sorrow, Rostam unleashed total destruction upon the land: for over a thousand leagues, cities were burned, warriors slain, and captives taken.
Eventually, the surviving Turanian nobles bowed before Rostam, renouncing Afrasiab and begging for mercy. Seeing their plight and mindful that King Kavus sat vulnerable in Iran, the wise elders advised Rostam to return home. Rostam agreed, packing thousands of elephants with gold, musk, furs, and weapons, and led his victorious army back to Zabulistan and Fars. Upon Rostam's departure, Afrasiab returned to find his kingdom a desolate ash-heap. Weeping tears of blood, he rallied his remaining forces for relentless counter-invasions against Iran. Yet heaven withdrew its favor: a devastating drought struck the lands, withholding rain for seven long years and plunging the realm into severe hardship.
