Story

It is a time of darkness. While the Sultan is off fighting a foreign war, his Grand Vizier Jaffar has seized the reins of power. Throughout the land, the people groan under the yoke of tyranny, and dream of better days.

You are the only obstacle between Jaffar and the throne. An adventurer from a foreign land, innocent of palace intrigues, you have won the heart of the Sultan's lovely young daughter. And in so doing, you have unwittingly made a powerful enemy.

On Jaffar's orders, you are arrested, stripped of your sword and possessions, and thrown into the Sultan's dungeons. As for the Princess, Jaffar gives her a choice, and an hour to decide: Marry him--or die.

Locked in her room high in the palace tower, the Princess rests all her hopes on you. For when the last sands drain from the hourglass, her choice can bring only a throne for the Grand Vizier...a new reign of terror for his long-suffering subjects...and death for the brave youth who might have been... Prince of Persia.
