I cannot open door that is east along passage from Golems room. I have killed all the halflings and stoked all the furnaces up. I have only been able to find the arm for the golem that is in the incubator. I killed all the sea creatures north of the room with the three adventures.

Question is, how do I open the door east along the passage from Golems room and do I have to put together the golem before entering that room.

Please Help.

yes, you put together the golem and he will open it (memories of Irenicus' Dungeon). The head is in the funky room with a gear-like looking thing in it- inside the funky gear-like thing- east of the furnaces.
