After clearing away the rubble, you crawl into the hallway that was
blocked off by the power released when Semiramis was freed from her prison. 
The hallway is full of dust, but seems rather sturdy here.  West leads back
into the main part of the catacombs, and east leads deeper into the
concealed hallway.
