Well, perhaps a plot where the characters are trying to solve the mystery of the previous owners of the mansion. They find old diaries and photos that lead them on a wild goose chase filled with creepy revelations about the mansion's past. For example, they might learn about some dark rituals that were once performed there, which adds to the overall spooky atmosphere of the fanfic.
In some creepypasta mansion fanfics, a really engaging plot is when the characters get trapped in the mansion during a storm or some other strange event. As they try to find a way out, they start to notice that the mansion seems to be changing and morphing around them. Hallways shift, doors disappear, and they are constantly being haunted by apparitions. This not only creates a sense of danger but also a feeling of being completely lost in a very hostile and unknown environment.
The caretaker of the mansion is often a memorable character. They usually have a dark past and seem to know more about the secrets of the mansion than they let on.
One idea could be that the characters discover a hidden room in the Creepypasta House filled with old portraits that seem to come alive at night. Another could be a group of friends getting trapped in the house during a storm and strange noises start coming from different corners, like scratching on the walls. Or perhaps there's a mysterious diary in the house that reveals dark secrets about the previous owners and it seems to have a curse attached to it.
Maybe there could be a Creepypasta entity that invades Equestria. Let's say a well - known Creepypasta character like Slenderman appears in Ponyville. The ponies are initially confused and then terrified as they start to notice strange things happening. The MLP characters then have to figure out how to get rid of this intruder and restore peace to their land. It could be a story about how the kindness and friendship of the ponies are put to the test against the malevolence of Creepypasta.
One idea could be that Thorin and Bilbo are exploring an old, abandoned mansion together. They discover hidden rooms filled with ancient treasures and must face various traps and puzzles to get out safely.
Well, a great plot for a Harry Potter mansion fanfic could be centered around a lost heirloom. The mansion was once owned by an important wizarding family, and a valuable heirloom has been lost within its many rooms and corridors. The characters embark on a quest to find it, facing various challenges like magical traps and puzzles. Also, the mansion could be a place where time behaves differently. People who enter might find themselves in different eras of the wizarding world, and they have to find their way back to the present while also uncovering the secrets of the mansion's past.
The doors that open to walls or empty spaces are really interesting. It's as if they were built for a purpose that we can't understand, maybe something to do with the spirits in the Winchester Mansion story.
The mystery. Creepypasta itself is full of mystery and the fanfics about couples add another layer. For example, the relationship between two creepy characters can be really unpredictable.
There are fanfics where the wolves are guardians of a cursed place. For example, a pack of wolves that are bound to an old, abandoned mansion. They protect the secrets within, and any intruder who stumbles upon the place is met with the wolves' menacing presence and the spooky happenings around the mansion. This creates a really eerie atmosphere for the story.
One idea could be crossing Slenderman with Jeff the Killer. Maybe they team up to haunt a small town, and the story could focus on the survivors' attempts to figure out their motives and weaknesses. It would be a great way to combine two iconic Creepypasta characters.
Well, often the unique and spooky settings are interesting. The manion (sic) in creepypasta fanfic usually has a very eerie atmosphere, with dark corridors and strange noises. It can create a sense of unease and mystery that draws readers in.
