Upon securing triumph on the plains of Khwarazm, King Kay Khosrow summoned his scribe to draft a magnificent royal dispatch to his grandfather, King Kavus. Sealed with fragrant musk and ambergris, the letter began with praises to God Almighty before detailing the ferocious nocturnal engagements that raged over three consecutive nights. The young sovereign announced the dispatch of three hundred severed heads of prominent Turanian chieftains alongside two hundred captured warriors to the Iranian court.
Meanwhile, the vanquished Afrasiab crossed the roaring Oxus like a raging tempest, seeking refuge with the forces of Qarakhan. Overcome with bitter grief, the Turanian monarch wept aloud for his slain kinsmen and fallen sons. Halting temporarily in Bukhara, Afrasiab convened a council of his surviving commanders. Heart-broken and battered, the lords of Turan recounted how barely twenty out of a hundred had survived the slaughter. They urged their king to withdraw beyond Chach to the legendary Gang-diz—the Paradise of Gang—a fortified sanctuary of lush beauty and thick ramparts where they could regroup. Yielding to their counsel, Afrasiab marched to Golzarion, resting three days amidst hunts with falcons and cheetahs, before entering the golden-bricked halls of Gang to drown his anxieties in wine.
Crossing the Jayhun, Kay Khosrow prostrated himself in gratitude to the Divine, distributing lavish alms to the poor and needy. He entered the province of Sogdia, bestowing wealth and restoring the region from ruin to splendor. Arraying his forces—the northern hosts of Bardaa and Ardabil under Gustaham, and the formidable southern champions of Nimruz under Rostam—Kay Khosrow issued a strict decree: any town or fort that surrendered peacefully was to be granted complete immunity and protection, while any fortress that resisted was to be razed. Advancing one hundred leagues without harming the peaceful populace, the Iranian army reached the idyllic haven of Golzarion, a paradise of forested plains and game-abundant mountains. There, by the crystal-clear waters, Kay Khosrow pitched the imperial pavilions, ascended his golden throne, and celebrated their march with a grand banquet that lasted until dawn.
