The Croups were a wealthy family before the Great War, but a bad deal in the stock market wiped out their fortune. The apocalypse wiped out their debt, but the radiation from the bombs turned the entire family into ghouls. Theodore Croup alone among the entire family was spared as the only member whose brain didn't rot with his body. He locked the surviving members of his family in the basement, being unable to kill them, regardless of how monstrous they had become. 
Soon after the war, Theodore discovered that feral ghouls do not seem to attack intelligent ghouls, and spent over two hundred years trying to train his feral family members to no avail, believing that he would be able to rekindle the flames of the "Croup family dynasty." 
On Theodore's personal terminal it is implied that he attacked his aunt out of anger, which might explain why she is dead upon arrival. 
The manor is a single building with three floors and a locked basement door leading to an interior area, all populated by many feral ghouls. The building is in a state of considerable disrepair.
The basement contains several leveled ghouls, Theodore's personal terminal and the corpse of Theodore Croup. The basement also houses a weapons workbench.
- A mini nuke in the basement, sitting on the couch.
- A Jangles the Moon Monkey in the basement behind the bookshelf.
- The Croup basement key and Croup bedroom key can be found inside the manor: The bedroom key is in a locked (Novice) desk on the second floor. This key opens the third level bedroom, containing a leveled glowing one and the basement key.
- The basement interior cell is not part of the settlement boundaries, therefore nothing can be built there.
- Despite the fact that the basement interior cell has windows inside, there are no windows from outside of the house.
- Sentient companions will say unique comments about the mansion feeling rather "unpleasant."
- Upon entering the basement, Deacon will sarcastically comment about backing you up the next time you "storm a ghoul-infested basement."
- In the nearby woods by Nahant Chapel, a mirelurk queen spawns behind the chapel.
- Despite being adjacent to a rather large body of water, none of it is inside the settlement boundaries, so a water purifier cannot be built here.
- The feral ghouls in the basement must be killed in order to access this settlement.
Croup Manor only appears in Fallout 4.
Behind the scenesEdit
- Croup is an archaic name for diseases that affect the throat such as strep throat, laryngitis, and bronchitis.
- pc ps4 xboxone Settlers at the Croup Manor may get stuck by falling off the cliff outside of the buildable area. The settlers can be returned to the area by fast traveling and then returning to the settlement.[verified]
- pc ps4 xboxone The bodies of the ghouls present on the settlement, even if initially moved, will return to their original designations as if the player character first discovered the settlement. This can be attributed to the unsightly hanging man in the manor's dining room. Additionally, this may cause ghouls to continue to spawn here, even after it has become a settlement. This includes a ghoul that is not aggressive toward those within the settlement until attacked, which spawns just behind the garage area, as well as the glowing one on the top floor, which has the ability to revive ghoul corpses close to it.[verified]
- pc xboxone If a lancer-initiate stands in front of the house, one cannot interact with them. Any shots fired at him will also have effect, nor will they garner a physical reaction on impact. [verified]
- ↑ Theodore's personal terminal - Journal Entry: 1/15/78: When my father said that nothing could change the "Croup Family Dynasty," not even the crippling debt from a bad stock market trade, he apparently didn't think about a world flooded with radiation poisoning...
Let me back up. When I watched the mushroom clouds rising, I thought that it was someone's sick joke. I'd prayed for something to wipe away the debt, but this was not what I had in mind. But I'd take a blue collar lifestyle over having the majority of my facial features slide off in my sleep...
- ↑ Theodore's personal terminal - Journal Entry: Journal Entry: 2/2/78: I've started to find that there are other survivors out here. Some of them look like roadkill, too.
- ↑ Theodore's personal terminal - Journal Entry: 2/10/78: Look, if I can still talk and function and act like a normal human being, then so can they. They just need a little nudge. The Croup Family will be back on top in no time!
- ↑ Theodore's personal terminal - Journal Entry: Who cares?!?: I swear to God I'm going to bust Aunt Belinda's head if she doesn't listen to me. You just watch!
