This passageway is very large, about 30 feet high in some places.  For
some strange reason the heat from the lake does not enter this passageway. 
There are strange markings all over the walls in many places.  Screams are
coming from within the room but it is impossible to tell what forms are
making the noise.  Evil is all around the room here.
A large fire dragon guards the way here.
