Perhaps it begins with a magical accident. Harry is known for getting into all sorts of magical mishaps. Maybe he casts a spell that backfires and somehow links his mind to the dragon language. This unexpected connection then serves as the starting point for him to begin learning Dragontongue.
He could start learning Dragontongue when he's on a quest. For example, if he's searching for a powerful dragon - related artifact, and the only way to get more information about it is to understand the language of the dragons. So he has to find someone or something to teach him Dragontongue in order to progress in his quest.
One challenge could be the sheer complexity of the Dragontongue language. It's not like any language Harry has learned before. The grammar and pronunciation might be extremely difficult for him, especially since it's a language created for a completely different fictional world.
I'm not entirely sure if 'Harry is ancient xover fanfic' is a statement or a really oddly - phrased question. If it's a statement, it could mean that in a particular fan - created fictional universe, a character named Harry is part of an 'ancient xover' which might be a crossover with some very old or classic fictional elements. But without more context, it's hard to be more specific.
Maybe a new exchange student from a far - off wizarding world where the concept of the Force exists comes to Hogwarts. This student notices Harry's strong magical abilities and decides to introduce him to the Force, starting his learning journey.
It can contribute by adding new perspectives. Fanfics like this allow fans to explore different 'what - ifs' regarding Harry Potter's story. It keeps the fandom engaged and thinking about new possibilities within the wizarding world.
Well, in many fanfictions, Naruto might start learning alchemy through a chance encounter. Maybe he meets an alchemist who sees his potential and decides to teach him the basics, like how to draw the transmutation circles.
It could be Hermione. Since she's Harry's close friend, she would likely play a significant role in a story where Harry is immortal. She might be the one trying to help Harry adjust to his new state or be involved in his adventures in some way.
His learning of etiquette might initially cause some strain. His Gryffindor friends are used to his more laid - back ways. But as he becomes more refined, he starts to interact better with students from other houses. For instance, he could have more civil conversations with some of the Slytherins who value proper behavior. This could slowly change the dynamic in the common rooms and in classes, as people start to see Harry in a new light.
Sirius might be shocked. He'd probably feel a mix of horror and protectiveness. He'd be horrified that Voldemort has used Harry in such a way and would be even more determined to keep Harry safe from Voldemort's clutches.
Well, Sirius is a very protective character. When he discovers that Harry is a Horcrux in the fanfic, he could initially be in denial. But once he accepts it, he'd likely start looking for ways to either protect Harry from Voldemort or find a way to remove the Horcrux part from Harry. He might also feel angry that Harry has been put in such a dangerous situation.
It depends on your personal taste. If you like crossovers between different fictional universes and are a fan of both Harry Potter and Skyrim, it could be really interesting. The combination of magic from Harry's world and the lore of Skyrim can create some unique and exciting storylines.
