GM Response:<br/><br/>@ Ria -- it is evident that someone has been here recently as you gaze out towards the floor.  You gather that the townspeople who had "prepped" the hall had been here, and had attempted to make the passage survivable, too, because they wrapped thick blankets around half of the blades to make them less lethal.  Also, a procession has displaced a great deal of dust from the ground, though their footsteps are many.<br/><br/>@ Iona -- This doesn't deter Iona, though, from pushing down here and thither with her mage hand.  After groping the ground for a few minutes, she finally pushes down on the telltale pressure plate, which causes the blade to swing down with a huge thunk.<br/><br/>Unfortunately, now it would require the party to cross the steel-sharpened blades.  DC 10 Dexterity -- but you slender maidens may take an additional +2 to your check.<br/><br/>
