Having swept the battlefield of Kamus and the armies of the Khaqan of Chin, Rostam called forth an elder scribe to write a royal dispatch in the Pahlavi tongue, perfumed with precious ambergris. The letter opened with magnificent praises to God Almighty—the Fashioner of the moon, Saturn, and the sun, the Bestower of glory, crowns, and strength, and the Creator of the heavens, time, earth, soul, and faith. Rostam recounted the battle fought between two mighty mountains, where a hundred thousand sword-wielders from Kushan, Shagnan, Chin, and India had gathered. For forty days the earth was constricted; rivers of blood soaked the soil for forty leagues, and the fortunes of enemy kings withered before the Iranian onslaught. He detailed how he had bound the enemy monarchs with his lasso from atop their war elephants, and declared his resolve to press forward until Ghoroy too was brought low.
Once the letter was sealed, Rostam entrusted it to Fariburz, son of Kay Kavoos, along with a thousand burden-bearing elephants, noble steeds, and the royal captives. With tears of admiration and reluctance to leave the heroic champion, Fariburz departed for the Iranian court. Rostam and his warlords spent the night in festive revelry, singing and drinking to their triumph. As dawn painted the sky in yellow silks, the war drums sounded, and Rostam mounted Rakhsh to journey onwards alongside Tus, Goudarz, and Gev, vowing to make the earth the burial ground for Siyavash's murderers.
Meanwhile, word reached King Kay Khosrow of Fariburz's arrival. The monarch rode out to meet him amidst the thunder of warhorns and drums. But when Khosrow's eyes fell upon the chained enemy kings and the vast spoils, he removed his royal crown, descended from his steed, and prostrated himself upon the bare dust before the Almighty. With a heart brimming with gratitude, he prayed: "O Pure Creator, Thou hast raised me from the grief of fatherlessness to the height of sovereignty. All the world is subject to my crown, yet I ask of Thee but one grace—spare the life of Rostam, my champion!" Rising from the earth, the King blessed the matchless defender of Iran and surveyed the fallen majesty of the captive lords.
