After obtaining the FIRE CIRCLE SCROLL as shown in the previous section, you'll return to the MAIN HALL. Go through the door on the lower level, northeast corner (door C in the diagram in the main walkthrough) to get back to the puzzle with the serpent levers.

- OR -

Since door C only opens from the other side, if you haven't opened it yet, instead go through the door in the southwest corner of the MAIN HALL (D in the diagram) to reach the PLANETARIUM.

Then exit through the doorway to the north to get back to the FIRE CIRCLE PUZZLE ROOM.

This puzzle consists of 7 serpent statues with levers that activate flames when pulled. Each lever can be moved up or down any number of times. Using any lever affects the flame on that statue, as well as the two other statues at the opposite points of the star. If a flame is off, the lever will turn it on and vice-versa. The goal is to light all seven flames at once.

Refer to the clue from the FIRE SCROLL, which begins, "For the serpents to live, all must first be stilled."

So, if you played around with the levers earlier and any of the flames are now lit, step on the raised tile with the star symbol on the east side of the room to extinguish all of the flames.

Now pull one of the serpent levers. Here we'll start with the one nearest the entrance, but you can start anywhere.

This ignites the flame on the first statue as well as those on the two statues at the opposite points of the star.

Now, following the instructions in the scroll to "provoke each in turn," move in either direction around the circle, using each lever as you go.

The various burners will go on and off as you do this.

Avoid the raised tile with the star symbol on the east side of the room, since it resets the puzzle. Only step there if you make a mistake and want to start over.

When you pull the seventh lever, "the circle will burn complete," meaning all burners should be lit, and blocks will rise from the floor in the middle of the room.

Regardless of which version of the game you're playing, you will need to follow the same path to the next area, but in the PlayStation version, solving the fire circle puzzle also releases a fire wraith, so you'll need to go quickly. Climb/jump up the blocks.

Walk to the left edge and jump straight up to grab the edge of the opening in the ceiling.

Pull up and run up the stairs to a fountain. Jump into the water and the wraith should follow and be snuffed out.

Climb out of the water and head down the short ramp into the next room.
