May be I was not specific enough? I am talking about the room with the terror spellbook, only reachable if you throw a pyramid up from a point in the big hall with the foorprints indicating the safe path.

Among others there is one grave which has 2 stone figures above it at the wall left and right. Both have the typical "interact" symbol, but I did not figure if these do anything. Anyone any clue?
