Kaen - While the others look at you and watch out for any trouble that might come
from the corridor ahead, you start to push the granite and search for secret passeges in the earth.
But you find nothing.
Looks like the corridor is the only way down.
I assume you proceed
The corridor continues further down, the shouts of the goblins stoped and there is a complete silence, you just hear the wind that enter the mine behind you.
After a min. walking along the corridor and the cart's rail (Not on the map) you can see another bent left up ahead, and further on you can spot numerous steps down beside the rail.
