Upon his liberation from Hamavaran, King Kay Kavus returned to Pars and reascended the Imperial Throne, establishing a golden age of righteousness and royal splendour. He dispatched alert, enlightened commanders to all four corners of his realm, stationing powerful garrisons in Merv, Nishapur, Balkh, and Herat to fortify the frontiers of Iran. So absolute was the reign of justice that the wolf drank peacefully alongside the lamb. Through his boundless wealth, majestic beauty, and Divine Glory (Farrah), earthly monarchs became his vassals, while even spirits, wild beasts, and herds yielded to his command. Above all, Kavus formally entrusted the supreme office of World Champion—Jahan-Pahlavan—to Rostam, attributing the prosperity of his reign to the hero's invincible sword.
Seeking to showcase his dominion over the cosmic realms, Kavus commanded the subjugated Divs to construct a magnificent imperial complex upon the heights of Mount Alborz. Carved directly into hard granite, two colossal halls were raised to a height of ten lassoes. Deep within the living rock, stables were anchored with steel pegs and granite pillars to house battle-trained steeds and royal transport camels. Two further halls were crafted entirely of pure crystal, studded throughout with glistening chrysolites, designed for feasting and relaxation. Another pair of chambers, forged from pure unrefined silver, was set aside as an armory for weapons and armor. Surmounting this complex rose a heavenly golden palace reaching sixty cubits into the sky.
Upon Mount Alborz, the seasons dissolved into eternal harmony; midsummer could not be distinguished from midwinter. The air blew rich with ambergris, and the rains refreshed like fine wine. Ruby and turquoise inlaid the walls in intricate motifs, preserving an everlasting spring where blossoms bloomed like the glowing cheeks of a beloved. Hearts were cleansed of sorrow and pain; only the bound bodies of the demons groaned under the weight of hard labor and royal retribution, while the world rested under the protective shade of Kavus's justice.
