[@Gnar The Missing Link]
Oh right Gnar, just to make sure I have this clear, but the room is as follows right?

Six statues surround a lone door, under each of their original positions is a tile.

On the wall is a circular diagram/table/chart with six square fillings. 

Just a bit confused if those words are all describing the same thing and simply used because Rena and the others see it differently.
