Maybe Harry is exploring an ancient and mysterious part of the Forbidden Forest. There, an old magic causes his wand to turn into a sword. The sword - wand seems to have a mind of its own and leads Harry to a hidden chamber. Inside, he finds a prophecy that can only be unlocked by the sword - wand. As he tries to figure out how to use it for this purpose, he has to fight off various magical creatures that are guarding the chamber. Eventually, he unlocks the prophecy, which reveals a great danger coming to the wizarding world and he sets off on a new quest with his sword - wand to prevent it.
In such a fanfic, Harry would become more experimental. He would start to combine his traditional spell - casting with the new abilities of the sword - wand. For example, he might try to cast spells while swinging the sword, creating unique magical attacks. This would make him a more unpredictable and formidable opponent. His character would also grow in terms of his relationship with magic itself. He would no longer take his wand for granted and would have a deeper understanding of the fluid nature of magic, which could lead to him being more open - minded about different forms of magic and magical artifacts in the future.
Perhaps it's a comical situation within the fanfic. Harry, being his curious self, accidentally licks Draco's wand while they are in a heated argument and it causes some sort of magical mayhem, like the wands start to emit strange lights and sounds.
Perhaps in this fanfic, there is some sort of danger in the wizarding world that can only be overcome by Harry and Remus having this special familiar - master relationship. Harry might turn Remus into his familiar to protect him from a dark force that is specifically targeting werewolves. As they navigate this new dynamic, they also have to deal with the reactions of their friends and the wizarding community at large. The story could explore themes of acceptance and the power of unconventional relationships.
In this fanfiction, it could be that a magical accident occurs during a potion - making class. Harry accidentally drinks a wrong potion which transforms him into a baby. Dumbledore then decides to keep Harry at Hogwarts, with the teachers taking turns to look after him. Meanwhile, Neville could be the one who discovers a clue about how to reverse the transformation by observing some strange behavior of magical plants in the school's greenhouse.
In the fanfiction, it could be that there is some ancient magic tied to Slifer that has a connection to Harry Potter. Maybe a hidden prophecy or a long - forgotten magical artifact causes the transformation. As Slifer, Harry might find himself in a situation where he has to communicate with other magical creatures in a different way. He could also face discrimination from some wizards who fear his new form, but also gain allies who recognize the potential of his new abilities.
One idea could be a fanfic where a character discovers a long - lost wand with a special power. For example, a wand that can open portals to different magical realms. The character then has to figure out how to use this power without getting into too much trouble with the Ministry of Magic.
The plot could involve a wand that has a special mark on it. The main character finds it in Knockturn Alley and realizes it's different from other wands. It might be a wand that was once owned by a powerful dark wizard. The character then has to decide whether to keep it and try to use it for good or get rid of it to avoid the potential danger it brings.
The custom wand in the fanfic could lead to a whole new set of adventures for Harry. It could be made from a rare material that attracts the attention of dark wizards who want to steal it. This would put Harry in a dangerous situation where he has to protect his wand and himself. The wand might also have a mind of its own and guide Harry to places he never thought of going, like hidden chambers in Hogwarts or ancient magical sites outside of the school.
Well, he might discover new and unexpected magical abilities. A different wand could have different properties and react differently to spells. For example, if it was made of a more rare wood or had a different core, it could enhance certain types of magic that his original wand didn't. Maybe it would make his Transfiguration spells more powerful or his defensive spells more effective.
In many Harry Potter fanfics, the wand handle can be a significant detail. It might be made of unique materials like dragon bone or enchanted wood. Some fanfic authors use it to symbolize a character's personality or heritage. For example, a character with a dark past could have a wand handle made from a blackened, gnarled wood that gives off an ominous vibe.
