When the sun entered the sign of Aries, filling the earth with radiance and new birth, Kyumars established the sacred rites of throne and crown from his high seat in the mountains. He and his followers clad themselves in leopard skins, introducing humanity to woven attire and refined sustenance. For thirty golden years he ruled, his royal glory shining like the full moon over a lofty cypress, while every wild beast and living creature of the earth gathered peacefully at his footstool, bowing in reverence to his divine grace.
Kyumars possessed a son of exquisite splendor and heroic nobility named Siamak, upon whom the king's heart was entirely anchored. But as the realm flourished, dark malice stirred in the depths: Ahriman, consumed by bitter envy, reared a demon child like a ravenous wolf and assembled a monstrous host to seize the crown of the world. Prince Siamak remained unaware of this rising shadow until the blessed messenger Soroush descended, veiled in leopard skin, to unveil the demonic plot.
Upon hearing of the foul enemy's treason, Siamak’s soul boiled with warrior rage. Lacking iron mail or war-harness, he wrapped his body in leopard hide and marched out to confront the dark forces. As the two armaments met, Siamak engaged Ahriman's child in single combat. Yet the Black Demon struck with twisted, malevolent claws, tearing open the prince's flank and casting his broken body to the earth. Siamak perished, leaving the host leaderless and the realm plunged into shadow.
When word of his beloved son’s death reached King Kyumars, his world turned pitch black. Wailing in agony, he descended his throne, tearing his hair and scoring his face in blood. The whole army donned garments of turquoise grief, and flocks of birds, beasts of prey, and wild game retreated to the peaks, raising their voices in mourning. For a full year the world sat beneath this shroud of sorrow, until Soroush descended once more with a mandate from the Almighty: to cease lamentation, gather the armies, and purge the evil demon from the face of the earth.
