Isle of the Dead -- Temple

Okay. I am in that little maze temple. I dont know the ways, and none of the signs, nor dead help. Does anyone know the way? I am so happy. Ha. I just got the map for this. I went to Isle of the Dead, because the other island was blocked by a little tornado thing on the map.

Go to the temple (the crown of the pic of the king) and read the tablets. The one on the right says something about go 13 north and 7 west or something like that. it will also talk about the great tree which is on the chin. go to the tree. Starting on the left of the tree, follow the instructions written on the stone tablet then dig a hole. If there is a hole there, drop down. If not, you did not follow the instructions.

Thanks. But the graves confuse me. Are those the directions to the cave?
