Lou's weapon easily punctures the building, though at least it seems to be made of wood. Despite this, the woman seems to take no notice. She sighs(which is even stranger than her speaking) and 'speaks' again, albiet sounding more rushed.
"It is unfortunate that you approach this with weapons that will do you no good. They are stonger than each of you. But they have the same failings. Might makes right for them..." she paused, glancing over her shoulder as if she heard something, but quickly turns back, "You must outthink those who cannot be beaten. Though you have fallen into their trap, know that there are many layers to it. You can still climb out. But be weary. The walls are also trapped."
And then she was gone. How she left, it was impossible to tell. It was more that she was there...and then not there. There was no transition or in between.
