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 am a large gray rat that scurries around in the castle walls. I like visiting the kitchen to snack on the bread crumbs. I carry diseases, so don’t touch me.
The smell should nauseate me, but you know what it really means? FOOD! Hello there little rats, would you like to nibble on a treat? Treats? Yes! Just don't touch me. Here you go, some little nibblets!  Don't mind these bodies, I'm the dishwasher for the torture chamber!  Some of these corpses didn't return their utensils before they were disposed - how rude! Oh I enjoy the bodies. I nibble on them as snacks when the picking in the castle are slim, though I think that's the reason I got so many of them diseases. Well then, do you prefer them fresh or a bit more . . . seasoned? I like em a little seasoned. Hmmmmm... so your but a little dishwasher downhere?  Yes!  And torture dishes can get so dirty!  Do you know how difficult it is to clean blood and bile from china?  Oh heavens, you have no idea . . . They feed the ones the set to torture, but try to run little old me off. What a shame. But, I may be able to help you with them dishes if ya like. I would love the help!  Perhaps you could clean the plates of food leftovers before I wash them? Yes, YES. And I am sure I could nibble off a little of them blood that stains them. *licks lips* Oh well the Sir Rat, come we me!  I would love any aid you can provide!
