Esfandiyar charges and scatters the Turks. Nastur arms, searches the field for his father, finds Zarir stripped on the ground, laments over him and rides to demand vengeance from the Shah. Goshtasb calls for his armor; his minister tells him to send Nastur instead.
With the Mobadan assembled and the Zand-Avesta beside him, Goshtasb puts the case of a rebellious son to the court in the abstract, gets the answer he wants, and has Esfandiyar chained despite his protest of innocence and sent on a black elephant to the fortress of Gombadan.
Esfandiyar enters the Ruyin Dezh as a merchant named Kharrad, with a hundred and sixty men sealed in chests among his camels. Arjasp grants him a house and a shop, laughs off rumors that the prince is crossing the Seven Stages, and bids him trade freely.
At night Esfandiyar opens the chests, sends his sisters to safety, storms the palace and kills Arjasp hand to hand. He seals the treasure, rides out with his hundred and sixty men, and leaves orders to cast Arjasp’s head from the wall.
Before the court Esfandiyar recites his service: the oath against the idol-worshippers, the battle with Arjasp, the chains his father put on him, the Seven Stages, the sisters brought home. He ends by asking what pretext is left for withholding the throne.
Katayun begs her son not to ride against Rostam, reciting his deeds and warning that no crown is worth his life. Esfandiyar agrees that binding Rostam would be shameful, refuses to disobey the Shah, and insists on taking his sons with him.
The two meet at the Hirmund. Rostam greets Esfandiyar warmly and invites him home; the prince returns the courtesy but insists Rostam must come before Goshtasb in chains. Rostam refuses the bonds, and they settle instead on one day of feasting.
Food is served, and Rostam’s appetite astonishes the camp; he demands his wine unwatered. Weighing his choices in silence, he finds shame in all of them, and warns Esfandiyar that Goshtasb has sent him to die. The prince fixes battle for dawn.
Rostam prays, then shoots the tamarisk shaft into Esfandiyar’s eyes. The prince falls, draws the arrow out, and tells the grieving Bishutan and Bahman that the wood, the Simorgh and Zal’s craft, not Rostam’s strength, have killed him. Rostam weeps over him.
Dying, Esfandiyar names Goshtasb as his true killer, gives his son Bahman into Rostam’s keeping to be reared as a prince, and sends bitter messages to his father, mother, sisters and wife. Zavareh warns that the boy will destroy them.
