In these fanfictions, you often see crossovers that blend the magic systems of Harry Potter and the lore of Dragon Age in unique ways. Regarding the gay aspect, it could be about a romantic relationship between two male characters, perhaps a Hogwarts student and a Dragon Age elf. Some stories might explore how their different worlds' values and cultures impact their relationship.
One interesting fanfic could be where Harry Potter discovers a hidden power within him that is related to Susanoo. Maybe he uncovers it during a battle against Voldemort. However, these types of crossovers are not as common, so you might have to dig deep into fanfiction websites like Archive of Our Own or FanFiction.net.
One great fanfiction could be about a wizard from Harry Potter's world getting lost in Sleepy Hollow. They might use magic to deal with the Headless Horseman, which would be really interesting.
One great fanfiction could be about a wizard from the Harry Potter world being transported to the world of Final Fantasy 13. Maybe they have to learn the new magic system there while also trying to find a way back home. It could be full of exciting battles and new friendships.
One common theme is the clash of different magic systems. Harry Potter has its own set of spells and magic types, while Dragon Age has its unique magic like blood magic. Fanfictions often explore how these two different magics interact when the worlds collide.
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.
Another concept could be that the Dark Arts in Harry Potter are somehow related to the dark magic in The Dragon Prince. A villain from The Dragon Prince tries to obtain a powerful dark magic artifact from the Harry Potter universe. This would lead to a race between the heroes of both worlds to stop the villain. The characters would have to learn about each other's magic systems quickly in order to succeed.
One great fanfic could be about a wizard from the Harry Potter world traveling to the Game of Thrones universe and taming a dragon there. Maybe they use magic to communicate with the dragon in ways that the people in Westeros can't even imagine.
One interesting fanfic could be where the magic of Harry Potter's world intersects with the dark and edgy aesthetic of Black Rock Shooter. Maybe Black Rock Shooter is a mysterious figure in the Forbidden Forest, and Harry and his friends encounter her during one of their adventures. She could have powers that are both magical and different from what they've seen in the wizarding world, leading to a whole new set of challenges and alliances.
One interesting fanfiction could be a crossover where the magic from Harry Potter meets the high - tech world of Final Fantasy 7. For example, imagine Harry and his friends being transported to Midgar and having to deal with Shinra while also using their magic. There are likely some out there that explore how the different magic systems interact, like how materia could be related to wand magic. Another aspect could be the characters' reactions to the different cultures. Harry might be shocked by the slums in Midgar, while Cloud and his group could be intrigued by Hogwarts and its secrets.
A common theme is the clash of magic systems. The magic in Harry Potter is different from that in Dragon Age, so seeing how they interact is a big part. Another theme is the cultural differences. Hogwarts has its own culture and so does Thedas.
