thanks for playing the game! I thank you for your persistence and hopefully you managed to get past that door!
Sorry if it's too tough, the map is huge so I do understand :<
if not, I can provide you with hints but not answers please! The tablets could also be an issue with my english.
The idea of this puzzle was to count the number of statues on each side of the map and do some calculations. The image above shows the right side.
So from north to south, top to bottom, top have 4 statues, middle is valued at zero by the broken bust and bottom 5
so the number on the right is 405.
000???
