Cruxel: The stones are a ledger, not a wall. Count the repeats in each row—do the numbers fall into a sequence? Look at the gaps, the mortar lines, the way a single stone is offset. Even a slight shift can spell a letter if you treat the stone’s position as a binary bit. Start with the first full block, note the number of stones, then subtract the next block’s count; the difference might map to ASCII. If the pattern breaks, that’s where the hidden message hides—try overlaying the stones with a simple cipher grid. Remember, the monks liked symmetry; their secret is often the asymmetry you can’t see at first glance.
