I tried a little setup to see how I would approach it, and made the mountain first, but I think the solution has to be the monastery fiirst so that I can get the placement right, and then build a mountain around  it in smaller pieces. I did a similar thing with my tree roots on the rocks on the side of a mountain. I started with the roots and gradualy added rocks till it looked like the roots were wrapped around them.  Just a case of getting to the root of the problem eh? :laugh:

Looking good so far, you seem to have a handle on it already.
