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.

local merchant
I am a local merchant.  I set up my wares in the town center.  People shopping in the market buy trinkets from me.
Odd I would have thought this was the type of thing a rat would enjoy  Even a rat doesn't appreciate the smell of corpse over my delicious scraps. What are you doing here? I am taking in the loss of life by the hands of men hungry with power. I do not understand such evil and at times it is good to look at the deeds done by evil men to keep oneself from turning into people such as that.  You are a good man, merchant. I can avenge these fallen men, if it means less men over my scraps. As a rat, I can scurry unnoticed in the castle walls and I carry disease that can wipe out those that come in contact with me.
