Temple Hexagram Chamber
When you enter the next chamber, you'll see a set of display stands and several dark areas. Walk Gabriel around the chamber and examine everything before picking anything up. Also, use the radio to ask Grace about the objects, the Solomon statue, and the Latin phrases before attempting to pick up any of the objects.

Move over to the display stand with the gold and leather glove. Pick up the leather glove; Gabriel will automatically put the glove on his hand. Walk over to the display stand with the fire and water. Use the camera to look inside the bowl of fire and spot the stone. With leather glove in hand, use the verb menu to pick up the stone.

Select the mirror where Gabriel appears old.

Walk over to the two statues. The one on the left looks like a demon, and the one on the right looks like a knight. Place the stone in the outstretched hand of the demon statue. When you do, the dark areas of the chamber illuminate revealing additional display stands (and the display stands you just used turn dark).

Next: Day 3, 9:00 pm, as Gabriel (cont.)
