They can introduce conflict. For example, if the 'creature of the night' is a powerful vampire clan that decides to take over Hogwarts, the main characters will have to find a way to defend the school. This creates a lot of action and suspense in the plot.
Well, 'creature of the night' in a Harry Potter fanfic could be dementors too. Dementors are these dark, hooded entities that lurk in the shadows and feed on positive emotions. They are most active at night, spreading their cold and despair. In fanfics, authors might explore their origin more deeply or create new scenarios where the characters have to face them in different ways than in the original books. They are a great way to create a spooky and tense atmosphere in the fanfic.
Familiars in fanfic can affect the plot in many ways. For instance, they can be used as a means of communication. If a wizard is in a dangerous situation and can't use magic openly, their familiar can carry messages to other wizards. They can also act as a plot device to introduce new magical elements. Say a familiar discovers a hidden magical artifact, that then becomes the focus of the story.
Monsters can be a major plot device in Harry Potter fanfic. They can change the relationships between characters. For example, if a monster attacks a group of students, it can make them bond together more tightly as they fight for survival. Or, if a character has a special connection to a monster, like being able to communicate with it, this can lead to a whole new sub - plot. The monster might hold a key to a mystery, like the location of a powerful magical object, and the characters' quest to get that information from the monster becomes a central part of the plot.
They can drive the plot forward. If a character takes an oath to find a powerful magical artifact, then the whole story can revolve around that quest. It gives a clear goal and motivation.
They can add drama. For example, if a character suddenly discovers they are a 'Lord', it can create a power struggle within the story. Others may be jealous or try to use the newly titled character for their own gain.
If the creature is a gentle and wise one like a unicorn, it could enhance Harry Potter's sense of purity and goodness. The unicorn's grace and magical essence might inspire her to be more in tune with the positive aspects of magic. For example, she might become more empathetic towards other magical creatures.
They can change the plot in many ways. For example, if a super - powerful character like Superman is inserted, he could easily solve some of the big threats that Harry and his friends face, like the Death Eaters. This would completely change the direction of the story as the main characters might become more reliant on this new character. Another way is by introducing new conflicts. If a character like the Joker from Batman is inserted, he could create chaos and new rivalries within Hogwarts that the original characters have to deal with.
When Harry has the power of teleportation in fanfic, the whole concept of travel and rescue missions is transformed. He can instantly transport himself and others out of dangerous situations. This power can also lead to new adventures as he can explore far - off places without the need for traditional means of transportation, thus opening up new storylines.
Rituals can also be a way to explore different magical cultures in fanfiction. For example, if a ritual from an ancient wizarding tribe is introduced, it can bring in new lore and magic. This can expand the world - building of the Harry Potter universe in the fanfiction. If the main character has to learn and perform this ritual to save the day, it not only affects the immediate plot but also enriches the overall story by adding depth to the magical world and its history. It can also lead to the discovery of long - lost magical artifacts or secrets that were tied to that ritual, which can further drive the plot forward.
The revelations might lead to new story arcs. For instance, he may have to learn about the responsibilities of his lordships. This could involve dealing with feudal - like obligations in the wizarding society, and it would open up a whole new set of challenges and relationships for him. Also, other characters may either support or oppose him based on these new revelations, which can drive the plot forward in different directions.
