Following the demise of Garshasp and with the Iranian throne left vacant, the realm faced looming peril from foreign foes. In this critical hour, the wise champion Zal summoned his valiant son Rostam and entrusted him with a vital mission. Zal commanded Rostam to lift his formidable mace, assemble a chosen force of brave warriors, and ride without delay toward the high peaks of Mount Alborz. There he was to seek out Keyqobad, a noble scion of the Kayanid line, deliver the praises of the realm, and relay the solemn message that the host and elders of Iran had adorned the royal throne for him, recognizing none other as worthy to wear the Kayanid crown. Zal charged Rostam to ride day and night without rest, ensuring Keyqobad's return within two weeks. Hearkening to his father's command, the mighty Rostam touched his brow to the earth in deep reverence, girded his loins, and swept forth like a tempest toward Mount Alborz.
