You have to place the story of the gods in correct order. You must do so with the ten pictures along with the ten plates of text placed directly below them. The first picture and plate starting at the top left will be as follows:
-Picture description: Osiris is standing before a seated female. -Plate text: "Osiris, son of Earth and Sky, is Pharaoh and Isis, his sister, is Pharaoh's wife. He brings knowledge to Egypt."
Open your inventory by Right Clicking and at the bottom of your video screen notice that at the bottom of your video screen you carry only a disc and a small stick. Go forward, then turn to the left. Walk forward twice towards the bandit camp. Talk to the guard using any conversation icon. The guard is very unfriendly and offers to shoot you. If you bother him again he will hit you over the head with his machine gun and you will be returned to your starting point in the desert. Turn to your right and climb up the hill. Turn slightly to the left and go forward towards the archway. Another guard spots you and beckons you over. The Targui will suddenly appear behind the guard and saves you. Turn back slightly to the right towards the arch and go forward once, then turn right and enter the cave.
Walk forward towards the glowing portal and to your right you can see all kinds of computer equipment. Look down on the ground before you. You will find the "Spinning Top" puzzle and the key to unlock the portal. Etched in the ground is a circle, crowned by five pictured markings. Refer to every marking with a number from one through five, from left to right. Each time you place the spinning top on one of the markings, it will trace a path and light a star at the end. You must learn the correct order to keep all the stars lit as some paths will cross and reverse the process. Once all five paths are traveled, the five stars will create a pentagram signifying the body. Start with the fourth marking (picture of the right foot). Determine the correct order until all five stars are lit. When the puzzle has been correctly solved, the portal will activate and your character will automatically step through.
