Sorry, I'm a bit thick. I read the excellent session reports but couldn't find the answer to my question?
I think Harleys post should make it clear, but here is the bit from the thread I was speaking of where I talk about it.
I need a clarification on something in this module. If the party heads up the west side of the keep and does NOT cause the avalanche of cyclopean stones, do they still see or come across the entrance to the B-1 area? I am a little confused as to how it is situated on the map.
Or will they see a different entrance once they enter the courtyard from the western broken down wall?
This confused me initially too..but it didnt matter because my people triggered the avalanche. IF you do not trigger the avalanche you do not find that entrance to the tomb of the fallen at this point. There is another entrance After you clear the tower of the beast and head down the stairs you'll see the rear entrance at area 1-1
when the text says "enter from the North West" its referring to the entrance post avalanche. when the text reads " enter from the South East" its referring to the tunnel
at Area 1-1.... I was still confused about the Tomb having two entrances, so I played if the players found the one via the avalanche the second entrance didnt exist.
Hope that helps.
