But instead of the peace he longs for, he finds his kingdom ravaged by war, and Kaileen is the target of a brutal plot. When she is kidnapped, the prince tracks her to the palace, only to see her murdered by a powerful enemy. Her death unleashes the Sands of Time, which strike the Prince and threaten to destroy everything he holds dear. Cast on to the streets and hunted as a fugitive, the Prince soon discovers that the Sands have tainted him, too. They have given rise to a deadly Dark Prince, whose spirit gradually possesses him.
