Hakotep's flying pyramid has been grounded, but the heroes must enter the ancient tomb to deactivate the fleet of smaller flying pyramids poised to attack cities across Osirion. Deep inside the Pyramid of the Sky Pharaoh, an untouched tomb from the heights of Ancient Osirion, the heroes face undying guardians woken from ageless sleep, culminating in a final battle with the reborn Sky Pharaoh Hakotep himself.
