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.

There are actually small sigils that are IN the tiles underneath their original positions. While the tiles aren't movable, the sigils are removable. 

The diagram/table/chart doesn't just have the six square fillings... but over 100 elemental square fillings, each being a single element and being in a specific order. It resembles something that can be found on Earth, but the layout is vastly different.
