In the very first area of Dorn's Deep, across the top of the map, I see from left to right, the main entrance, a cave entrance, another cave entrance, and finally some sort of tower-like entrance. I hit the Ettin caves at the bottom of the m ap and every place except the bridge. I can't seem to find a path to the two eastern-most entrances at the top of the map (one cave entrance and the tower-like structure. I can see the door icons indicating an entrance, but my characters are only able to walk within view. I tried clicking in front of the door icons, but the characters only bunched up at the edge of the path and would go no further. Is there a path to those doors, or can they only be reached after crossing the bridge in the south-east corner of the map?

Those areas are reachable before crossing into the next map east. I think what you have to do is right at the map entrance head immediately norht, and take a narrow passageway that runs across the northern border of the map.

Yeah ... I found it right after I posted this. It runs from the main entrance on a narrow path over the top of the first cave entrance. Thanks.
