Servants' Quarter
You take the key that you fished from the well out of your pocket and slot it into the keyhole. It goes in all the way. You try turning the key and the lock clicks. You then turn the turn knob and push the door open. You walk into the room, which is rather spacious. There is a very long table stretching from one end of the room to the other and it is lined with chairs, at least a hundred of them. The room has very little decoration with just a few emblems of swords on the walls and a handful of stone sculptures against the walls. Other than that, the room has nothing. The floor does not have fancy carpet like the previous room and the materials of the furniture in the room are much lower quality too.
There are three more doors in this room. One door across the room from the entrance. The two other doors are on the left and right side, perfectly aligned in the center of the room. Seeing how there is nothing outside here, the growl you heard must have come from one of these rooms. You go to the door on the left side of the room first and go through them in a clockwise direction. You look at the knob and check under it to see if there are any keyholes. There are none. You turn the knob and open the door.
You walk to the end of the room and around the long dining table until you are standing in front of the center door. This door has a wooden plaque on it with the words, “Head Butler” carved in it. A very appropriate place to have the person in charge overlook everyone else. Unlike the last door, this one did have a keyhole but you try the knob anyway. The door is surprisingly unlocked.
You approach the last door in the room, opposite the dormitory for the maids. Based on context clues, you can already guess that this must be the dormitory for the male servants or the butlers. Once you get to the door, you find a plaque that tells you that your guess is spot on. This room is indeed the dormitory for the butlers. However, you find it a little strange how the rooms for the male servants have plaques while the dormitory for the women does not. Either someone tore it off or there was never one to begin with, the latter being the more likely option. Inequality was common back then so that may be the reason to explain it.
