Set sometime between The Sands of Time and Warrior Within, Forgotten Sands sees the Prince visiting his brother for a little warrior training and instruction in the art of war. Picking up with a scene eerily reminiscent of Sands of Time - the Prince sneaking into a fortress under siege - and things quickly go to Hell. The Prince's reckless brother unleashes an accursed army, leaving the Prince to put the demons back in their box.
