A possible storyline for a mute child in Harry Potter fanfiction is that they are a transfer student from a far - away magical school where being mute is seen as a sign of great power. At Hogwarts, they initially face challenges because of the different culture. But as they show their unique magical abilities, like being able to sense danger through vibrations in the air, they gain respect. Another storyline is that the mute child is a descendant of an ancient wizarding family with a curse that causes muteness. They must break the curse while also dealing with the normal Hogwarts drama, like exams and rivalries.
One storyline could be that the mute child discovers they have a special power related to their muteness. Maybe they can silently communicate with ancient magic artifacts that no one else can. Another storyline could be that they are wrongly accused of a crime because they can't defend themselves verbally. Then they have to find a way to prove their innocence through their actions and non - verbal magic. A third storyline could be that they befriend a house - elf who also uses non - verbal communication, and together they uncover a secret plot within Hogwarts.
For a mute child in Harry Potter fanfiction, here are some storylines. They could be part of a secret group within Hogwarts that uses non - verbal magic for good deeds. They communicate through a special code of wand movements. Or they could be on a quest to find a cure for their muteness, which leads them to explore dangerous and unknown parts of the wizarding world. Also, they might get involved in a mystery surrounding a missing magical book that only they can decipher because of their unique way of seeing and understanding magic, even without speaking.
Another storyline might involve a magical artifact that accidentally causes Harry to regress mentally. He could then start seeing Hogwarts in a completely different light, like it's a huge, exciting playground. He might be more interested in exploring the castle's secrets for the fun of it rather than for any serious purpose, and his relationships with his professors also change as they have to deal with this new, child - like Harry.
One possible storyline could be that the child is a result of a relationship Harry had during his later years at Hogwarts that was kept secret. Maybe it was with a foreign witch he met during one of his adventures outside of Hogwarts. The child could inherit Harry's magical abilities and also some of his personality traits like his courage and sense of justice. Then the story could focus on how the child discovers his or her true identity and the legacy of being Harry Potter's offspring.
Another reason might be related to his magic. There could be some sort of magic interference or a spell gone wrong that affects his ability to speak freely. Maybe a curse was placed on him that makes him mute in specific circumstances, or there's some internal magic struggle within him that causes this selective muteness. This would add an interesting layer to the story and could be explored in many different ways in the fanfiction.
One possible storyline could be a character getting hit by a powerful dark spell during a battle, which causes brain damage. Then the story could revolve around their struggle to regain their magical abilities and memories. For example, if Harry were to be the one with brain damage, he might have to relearn spells and how to interact with his friends in Hogwarts.
One possible storyline is that the Potter Manor is under attack by a new dark force. Harry and Ginny have to defend it using their skills and the help of their friends. Another could be that they are renovating the manor and discover some long - lost family secrets during the process.
A possible storyline is that Ruby Rose, with her combat skills, trains the students at Hogwarts in self - defense against the dark arts. Harry Potter might be initially skeptical but then realizes the value of her unorthodox methods.
One storyline could be that Harry, after the events in the wizarding world, decides to take a break and travels to Gotham. There he meets Bruce, and they end up teaming up to take on a new threat that combines magic and Gotham's usual criminal element. Maybe a villain who has somehow gotten hold of a powerful magical artifact and is using it to wreak havoc in the city.
One possible storyline could be that the hobgoblin is a magical creature that has been trapped in Hogwarts for centuries and Harry discovers it. The hobgoblin then teams up with Harry to uncover the secrets of Hogwarts that are related to a new dark threat. Another could be that the hobgoblin is a messenger from an unknown magical realm and it chooses Harry to be the one to communicate with its realm.
Well, it could be a story where Harry is tricked into believing that Muggles are responsible for some great harm to his loved ones in the wizarding world. So, in his rage and misdirected sense of justice, he starts targeting Muggles. But this is a very un - Harry - like behavior as the real Harry is all about protecting the innocent, whether they are wizards or Muggles.
