He could learn unique Irish magic spells as part of his apprenticeship.
Perhaps in this fanfic, the Irish school has a long - standing relationship with Flamel. Harry is chosen as an apprentice because of his prior experiences with magic and his unique ability to face challenges. At the Irish school, he meets new friends and foes. He has to learn the secrets of Flamel's alchemy, which might be different from what he has known before. There could be a hidden chamber in the school where Flamel's most precious works are stored, and Harry has to protect it from dark wizards who are after the powerful magic within.
It could be an original character created just for the fanfic. Maybe a young wizard or witch who has a special talent for alchemy and catches Flamel's eye.
The plot could revolve around Harry's apprenticeship under Nicholas Flamel. Harry might be chosen because of his unique connection to Voldemort. Flamel could see that Harry has a special destiny and decides to train him in the ways of alchemy. This could include learning how to transmute substances, understand the properties of magical elements, and use alchemy for defense and offense. Harry could also learn about the history of magic through Flamel's eyes, which is much longer and deeper than what he has learned at Hogwarts. There could be a lot of adventures where Harry uses his newfound alchemical knowledge to fight against the forces of evil.
Yes, often there are unique plots. For example, the apprentice might get involved in secret alchemy experiments Flamel was famous for. They could discover new magical potions or spells, and have adventures in the wizarding world that are different from Harry's main story in the original books.
Perhaps Harry discovers a long - lost magical item in one of the vaults during his apprenticeship. This item could be of great importance to the wizarding world, and he has to decide whether to keep it a secret or reveal it to the authorities. Along the way, he has to deal with the greed and envy of some of the other employees at Gringotts.
Well, in such a fanfiction, perhaps the train could be a key to finding Flamel's hidden secrets. Maybe it has some sort of magic protection put in place by Flamel himself. It could be that the train is transporting something very important related to Flamel, like a special ingredient for his alchemy.
Obviously, Harry Potter and Nicholas Flamel would be the main characters. Harry as the apprentice and Flamel as the mentor.
Well, one possibility is that Harry would learn a great deal about potions from Snape. Snape is a master in potions, and he could pass on his in - depth knowledge to Harry. Harry might also gain a different perspective on Snape. Instead of seeing him as the strict and often mean professor, he would start to understand Snape's complexity. This could lead to a more positive relationship between them, and Harry could become more skilled in magic that Snape specializes in.
In this kind of fanfiction, Harry Potter might gain access to the Flamels' vast knowledge of magic. Maybe he would learn ancient spells and potions that are not taught at Hogwarts. He could also be protected by the Flamels' powerful magic, making him safer from Voldemort and his Death Eaters.
In this fanfiction, Harry could learn a great deal of advanced magic from Flitwick. Maybe he would master some complex spells that are not taught in regular classes. For example, he could be taught the secrets of charm magic at a much deeper level, which would help him in his battles against the Dark Arts.
