The rat den is a disgusting, musty room deep inside the tower sewers. This is the area that the rats pull the bones of the treasure seekers, so they are able to get full access to all of the decomposing meat on the bones. Around the room are empty crates, that are broken and falling to pieces. Scattered glass litters the floor, broken ale bottles where some of the poor have tried to stay in the den, before the rat's had over taken it. There are torches on the wall, but dim now, as no soul wants to see the what the light would show. There are rat's nests in the corner, bits of straw, cloth and other odds and ends the rats have dug up.

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.
Oh, how I love my home here in the sewers. Greetings, wingless cousin  You have come to visit my vast accommodations. I would be glad to be  your guest, cousin.  I have many treasures here in my den to show you. I was just admiring the beautiful shiny glass  That is from those that stumble down here uninvited. What remains is over falling off those bones. Ah, you prepared dinner! For you only the best drunks will be severed.  Alcohol infused dinner! Cousin, how can I ever thank you? You must return with me for a vat of blood one of these days  Thank you dear cousin. Shall we dine. After you, my wingless friend
