SPOILER!!!
Hello!
(Sorry if my english isn't totally correct)
I'm stuck infront of the door with three floor levers infront of it. I've run through the center door, gone to the door to the right and put the rook in the barrel besides the door (I've read that you shoul'd do this). Then I ran out through the center door again, pulled the right lever and I guess I shoul'd do something with the chess king to go to the door faster. But HOW? I right click on the chess king and all I can do is "examine" and "drop" (I'm a fighter so I can't "cast spell"). By the way: Both the king and the rook is unidentified, does that matter?
Thanks ..
