You are walking along a path made of interlocking sandstone, worn and
patched in several places.  The stones crumble slightly under your feet as
blocks of the retreat's eastern wall rise to your west.  The stones begin to
become spaced farther apart until they give way to the packed dirt in front
of a modest-looking building.
