Okay...I guess I have been playing for just a little too long. I can't find the third piece for the circle. An other suggestions for this particular place. Any and all help would be appreciated. Just wanting to clean this dungeon up and move one.

Anyways, if someone doesn't mind helping me out.

Thanks : )

Once you get the first two peices and all three rituals (morn, noon, evening), you need to return to the first set of rooms and talk to the statue head. He'll quiz you on the rituals, when you get all three right, he completes the circle. Quick save before speaking to him, this makes figuring out the puzzle easier...

Just in case you figured out the ritual beforehand and got that piece first or second, the other two segments can be gotten from the shade beyond the lava room for giving it the skeletal remains and from a hidden compartment in a chamber beyond the hall with the lettered floor. It's on the wall, and there's a talking shadow guarding it, too.
