Follow the hall back to the room with the altar and stairs leading up and outside. Go up the stairs and return to the door leading to The Obelisk of the Moon. Enter.

Go to the room with the obelisk and 4 exits. Go into the rooms opposite and to the right, placing the skulls on the red shelves. Enter the room to the right or left when the secret doors open. Go through the door leading to the Palace of Columns.

Go forward, then take your second left when you come to a hallway. Follow the hall down to a large outdoor area with a pyramid-like structure on one side and several columns on the other. Go down the narrow hall between the columns.

Come to a hall with many pillars and red carpet. Notice 2 doorways in front of you, one on the right and one on the left. Go through the one on the right and down a short hall to an area with lava.

Hit the button on the wall to the left and cross the bridge that raises up out of the lava. Hit the button on the wall across the bridge, raising another bridge up to your left.

Backtrack to the hall with columns and red carpet. Go through the other doorway and cross the bridge you just raised. Follow the catwalk around to the teleporter. Go through to the Tomb of the High Priest.

Walk forward and come to a large area on the left with the second piece of weapon #4. Go straight across the arena and turn left down a hall and a short flight of stairs.

Come to a large room with a platform that lowers from the ceiling. Go straight across to the room with a skull wizard and Tomb of Power. Turn around and go into the passage on either side of the stairs you came in on.

Go to the back of the area with the green stone walls and the wall will slide back. Run down the passage quickly so as not to get smashed.

Come to a balcony overlooking another skull wizard.

Drop down and open the sarcophagus the skull wizard was inspecting, which will open a passage under the balcony you dropped down from. Follow the passage to a room with the Air element.
