Following the events of Prince of Persia and Prince of Persia Epilogue, the story begins with the split of the Prince and Elika. While Elika stays with the Ahura, leading the resistance against Ahriman, the Prince departs in search of the king of The City of New Dawn, in the hope that he can summon Ormazd, due to his affinity for the remnants of Ormazd's power. But here, the Prince finds a new ally, Zal, who introduces himself as one of the king's Magi and teams up with Prince to save the City of New Dawn from corruption and ultimately stop Ahriman. Later on, Zal reveals that the King was split in two by the Corruption: into a corrupted beast and into himself. The Ancestor, a character that had occasional helped the Prince and Zal, guides them to find a special power to save the city. This power then fuses the Prince and Zal into one being that preserves both Zal's powers and the Prince's acrobatics. Together they face and defeat the king's monstrous half. The defeat of the beast frees Zal from the Corruption, but also causes him to perish. The Prince then frees the land from the Corruption by reaching the city's seal. In the end, the Ancestor leaves a message of hope for the Prince, promising that, in time, an inner power would be revealed and new ally would be found.
