It is piled high with the bodies of those that did not survive the torture process. The smell is absolutely nauseating and the rats are multiplying faster than the castle can be rid of the corpses.

I hope my father doesn't pick that old, crusty Viscount as a husband for me.  I don't understand why I can't just stay here and run my father's keep.  I love the flute.  Dawn is my favorite time of day to walk the turrets
Father sent me down here to torture the prisoners with my flute practice.  I hate it down here! Oh uh, maybe it isn't so bad, why don't you play a little for me? Sure, I guess.  As long as you promise not to make fun of me like the prisoners!  Aw no, I won't make fun of you promise, cross my heart and hope to die, stick a needle in my eye.  Alright, this one is called The Mermaid and the Fisherman.  Here goes nothing! Oh ohhhh....that...that is quite.....ummmmm You hated it too! Just like the others!  I am trying my best!  Maybe it will scare away that boy father wants me to marry though... No, it was great! I loved it, I really loved it. Sure.  Whatever.  I don't care anyway! So why are you down here?  Seems like a filthy place even for a rat. There aren't many places I am welcome unfortunatly I feel the same way sometimes.  It makes you kind of sad, doesn't it? What are you talking about, everyone loves a Princess, no one loves a rat.
