Post any secret areas you discover thru the game here, or any place where you found something that you think leads to a secret areas.
For instance after i exited the goblin prison and went to the lift, there were two pressure plates, one of shich had stones on it. I took off the stones from the first one and put a stone on the second one and a wall opened up. I foundalot of useful stuff in there.
Another on is in the goblin chiefs room (the sleeping goblin) where you get the authorization and a key. Near the bookcase there is a brick that can be pushed - it raises a wall and reveals a chest. There are some gold coins there.
