Turn around again and enter the other door. Go through the fake wall and back up the stairs. Go around the box to the other side. Go down the hall and open the door. At the sundial, press the button repeatedly until it reads 12:00. Go down one of the ramps and take the hall around to a barred room. Walk near the doors and a door will open above. Go back to the pit with the box at the center. Jump across and enter, falling down to grab the Lower Crown of Egypt. Walk up to the bars to open them and walk through. Go back and take the teleporter leading back to the Palace of the Pharaoh. Now go back to the teleporter leading back to the Temple of Horus by first going back through the pipe and turning right at the teleporter. Enter and find your way back to the Chamber of the Sun (the room across the red bridge). Break the door and grab the staff of Nefertum. Enter the blue teleporter and go back to the room with the three red teleporters. Turn right and head for the teleporter leading to the Temple of Nefertum. Return to the contemporary Wheel of Time. Jump onto the wheel and leave the staff, revealing a button. Hit the button repeatedly until it's at the Constellation of Isis. The beams of light will appear and merge. When they subside, go get the Upper Crown of Egypt. Find your way back to the teleporter that leads to the Temple of Horus and enter it. Put the crowns down on the short pedestals flanking the ankh on the floor. The ankh will descend to a room below. Follow it down and confront the third rider, Pestilence. Take refuge from Pestilence in a back room. Pestilence can't enter this room, but his flies can.
