In the old graveyard there was a horrifying shriek and then just clicking, as if someone were chewing on something very insistently. Near the corpse of the guard I saw a hideous creature chewing the entrails of that poor man. His face was covered with blood and human remains, and on his face were horrible yellow eyes that were completely empty; showing that this creature had no soul.
