Oh also I have read on line Hermaeus Mora is supposed to appear and talk to me but I have not seen this NPC
(EDIT) After watching a video on youtube I think the first time I went there Mora DID talk to me, but I didn't look up at him. I recall the dialog of him talking. But the tunnel still wasn't moving.
Are you sure you haven't missed a switch somewhere?
Well from the videos I have seen on Youtube that moving tunnel is supposed to move at both ends but only the end I enter into it is moving. When I run to the end of that tunnel its not moving. It's just pointing at some tentacle monster that is on the far left. If the tunnel moved to the right side of the map there is a platform for me to activate a switch to bring down another rolled up bridge, in either case I don't know why the bridge isn't moving.
I wonder if a water walking potion will allow me to walk on this black shiny water so I can just by bass this bridge.
I read online the water walking boots should allow me to walk on the blank shiny water so I assume the potion will work to (haven't found these boots yet, maybe I will just do that first). Ill use the shout Ethereal to make sure I don't get hit by a random tentacle as I book it to the other platform and bypass the swinging tunnel.
