releases Mariam, who discloses the Emperor's goal to obtain the holy rings, her ring having been taken. The group returns to Mahamoud, where Kala Han reveals that the third ring is hidden in a tomb near the village of Uruk. Mariam, grateful for her rescue, gives the Prince an amulet capable of putting the dead to rest. At Uruk, the group retrieves a hammer that can open the tomb from the hideout of Ali Baba and his bandits, who have been terrorizing the village. Upon retrieving the third ring, the Prince is contacted by Jamshid's spirit, who warns the Prince of Ahriman's plot to escape his imprisonment by destroying the rings. Outside the tomb, the Prince is tricked by Al, disguised as Mariam, into relinquishing the lamp. The resistance group finds the Prince in Uruk and recruits him into an operation to liberate Shadam. The Prince infiltrates the castle and confronts Al, who appears to hold King Shadam hostage for the other two rings. After taking the rings, Al reveals the King to be a zombie reanimated to serve Yufurat. After being forced into battle with the King and the Jinn, the Prince uses Mariam's amulet to put his father's spirit to rest. The group returns to Gylan and defeats Al before witnessing the Emperor destroying the rings in a ceremony. As Ahriman returns to the mortal realm and kills the Emperor, the group flees to Mahamoud. The Queen recalls a prophecy by Jamshid foretelling the appearance of the Tower of Ziggurat, which would tie the physical and spiritual realms together upon Ahriman's return. Kala Han also informs the group that inserting the rings' ashes into the lamp will restore their original power. At the top of the Tower, the group encounters the Roc, who can fly between worlds. The group ventures to the spiritual world and faces Ahriman in a final battle. They weaken him into a state where he can be locked away once more with the rings, which have been restored by the group's hope and resolve. After returning to the mortal world, the Prince ascends to the throne and weds Mariam, and Sindbad becomes the captain of his father's ship.
