In the third room in the orc passage after you go down you are here:

A Rough Tunnel
Long cobwebs stretch from wall to wall, forming thin nearly transluscent
nets across the rough tunnel. Beneath the webs the stone walls bear the
marks of crude mining, long tool marks and deep pocks marring the rough
jagged surface. Thick beams of dark wood shore the tunnel, running up
from the uneven debris covered floor to the ceiling above, the entire
length of the knotty wood bowed and splintered. Northwards the tunnel
continues a trek through the webbed rock, a steep incline to the south
obscurring any view of what might lie in that direction.

If you look south you see:

A roughly formed tunnel leads on through a path of thin webs.

However there is no exit south nor any hidden exit.
