Welcome to the site! :smile:Let me see if I remember this quest correctly..First, you follow Paratus into the Armillary chamber, place the crystal, and then cast Flames/Frostbite on blue circles on the floor (or the crystals directly) until each beam of light above is focused on the center. You then press the buttons until the light beams line up with the mirrors. After you solve the puzzle, you just talk to Paratus.I don't remember even placing the crystal after talking to Paratus. Maybe it was used when you activate the Armillary, but I'm not positive. Do none of the other controls work, either?
