A more complex idea could involve the magic systems of both worlds. The magic in 'Harry Potter' is more about spells and potions, while in 'House of the Dragon' there is magic that seems more in tune with nature and prophecy. A fanfiction could explore what would happen if these two magic systems collided. Maybe a Hogwarts professor tries to study the magic of Westeros and discovers new ways to use magic that were previously unknown in the wizarding world.
Finally, when writing, try to blend the two styles of storytelling. 'Harry Potter' often has a sense of wonder and discovery, while 'House of the Dragon' has a lot of political intrigue and power struggles. Incorporate elements of both into your fanfiction. You can start with a small idea, like a dragon egg being found in Hogwarts, and then build on it, creating a story that is both engaging and true to the essence of both 'House of the Dragon' and 'Harry Potter'.
One interesting crossover could be the use of magic systems. In 'Harry Potter', magic is more about spells and potions, while in 'House of the Dragon' there is a different kind of magic related to dragons. Maybe a story where a Hogwarts student travels to the world of 'House of the Dragon' and tries to understand their magic.
In many fanfictions, Harry might use his powerful spells like the Stunning Spell or the Killing Curse if the story allows for such dark magic use. He could also use his intelligence to outwit the dragon, perhaps finding a weakness in its armor or behavior pattern and then using a well - timed spell to defeat it.
It could be that the dragon was an egg he found by accident. He, being curious and having a soft spot for magical creatures, took the egg and hatched it, thus becoming the owner of the dragon. In the wizarding world, there are often unclaimed or lost magical items and creatures, and Harry might have just stumbled upon this dragon egg.
There's also a possibility that it's a Chinese Fireball. These dragons are very beautiful and powerful. In a fanfiction, the author might choose this type of dragon for Harry Potter to own because it would add an element of exoticism and grandeur to the story.
Hermione Granger and Rhaenyra Targaryen. Hermione is known for her intelligence and knowledge - seeking nature. Rhaenyra is a strong - willed female character in 'House of the Dragon'. If combined, Hermione could perhaps use her intelligence to help Rhaenyra in the political battles in the Seven Kingdoms, while Rhaenyra could teach Hermione about the ways of the Targaryen court.
Yes, it could be. Dragons are quite prominent in the Harry Potter series. For example, there are dragon challenges in the Triwizard Tournament. So a fanfiction exploring Harry as a dragon fan makes sense and might be popular among fans who love the more fantastical and dangerous elements of the wizarding world.
Well, in fanfiction about the House of Potter, Fleur's rise could start from her initial encounter with the Potter family. She might initially be seen as an outsider, but as time goes on, she earns their respect. Her beauty and magical abilities are obvious assets. However, it's her loyalty and ability to adapt that really make her rise. For instance, she adapts to the British magical society's ways while still maintaining her own identity, and this makes her an important part of the House of Potter in the fanfic world.
