Oh and how exactly does the 'Altar Of Time' work? I've opened thoe door and got the Solid Key so I've got past the puzzle, I'm just curious as to how the forcefield was deactivated...
I don't know how far you've gotten on the road to finding the last Master Key, so I hope I'm not revealing too much. You don't have to find Turquoise Keys; they are not necessary. They're bonus items, found in secret areas. You can get some cool stuff behind the Turquoise Key doors, but there's nothing required.
Anyway, in order to find the last Master Key, you'll have to open the 'Hail To The King' door. If you have something "kingly" in your possession, then place it in the alcove. If not, you will have to search for something of that sort.
A bit more overt of a hint:
Have you opened the skeleton lock in the Couatl room? You will need the cooperation of some skeletons in order to gain access to the skeleton key, of course.
EDIT: Oops, I forgot to explain the "Altar of Time." It was a somewhat odd puzzle, basically, the solution was to use a magical box. It's based upon a hidden room containing a fireball launcher and gigglers running around triggering giggler generators. When you've frozen life, no more gigglers will be generated, and when all the gigglers are dead, the forcefield goes down. However, I think that once you have "enabled" the puzzle (by standing in front of the altar), using a magical box anytime, anywhere will clear the forcefields. So, if you saw the area, contemplated it a little, got stuck, left, fought some battles elsewhere, used a magical box, and then came back, you would find it had mysteriously been solved!
