What are the common plot elements in Harry Potter and Arturia fanfictions?

Yes, there are quite a few. Some might explore what would happen if Arturia was a student at Hogwarts. She could bring her unique magical abilities and chivalrous code into the wizarding world. For example, she might interact with Harry Potter and his friends in a way that changes the course of some of their adventures. There are also fanfictions that could involve Arturia facing off against Voldemort, which would be an epic battle of two very different forms of magic.

A common plot element is danger. Usually, Daphne is in some sort of peril, like being attacked by dark creatures or caught in a trap set by dark wizards. Another element is the element of surprise. Harry often discovers Daphne's situation by accident. For example, he might be exploring an old abandoned building in Hogsmeade and stumble upon Daphne in trouble.

Yes, one common element is the use of magical herbs. In many fanfictions, herbs like dittany or mandrake are used in the cleansing ritual. Another is the presence of a powerful wizard or witch to perform the ritual. Often, it's an older, more experienced character.

One common plot device is the discovery of her royal lineage. It usually happens in a dramatic way, like finding a hidden letter or a magical object that reveals her true identity. Another is the conflict between her wizarding life and her new royal duties. She has to balance things like going to Hogwarts and attending royal functions. Also, there's often a love interest from the royal court, which creates a love triangle with her existing relationships in the wizarding world.

False accusations are very common. Usually, Harry is wrongly blamed for something he didn't do, like being involved in dark magic activities.

Frequently, in these fanfictions, the soul bond is shown as a glowing or warm feeling between Harry and Ginny. It can be felt physically, like a gentle tug towards each other. Their bond may also be linked to prophecies or ancient magic. Some stories might have it that their bond was foretold long ago, and they are just fulfilling a magical destiny. This gives the relationship a sense of grandeur and importance in the overall Potter -verse.

One common plot point is that Harry often has to find a way to get past the Dementors in Azkaban. He might use the Patronus charm in a new and creative way. Another is that he usually has to overcome some sort of magical obstacle or security measure in the prison. And of course, there's always the emotional reunion between Harry and Sirius.

One common plot element is the idea of Harry Potter having some form of immortality and then getting involved in the world of Hobbits. Maybe he uses his magic to help the Hobbits in some way, like protecting them from a new dark force.

Another element could be the interaction between the wizarding world and the Muggle world of cars. Harry might have to hide his magic while fixing cars in the Muggle world, or he could introduce some magical car features that amaze the Muggles. In some fics, there could be a conflict when other wizards don't approve of Harry using magic in such a Muggle - oriented way. This adds drama and tension to the story.

Well, often there will be a focus on Harry having to keep his true identity a secret even from his friends. There could be a lot of cloak - and - dagger type situations where he has to meet with double agents or decode mysterious messages. Also, his skills in Potions and Transfiguration might be used in a more espionage - related way, like creating potions to make people tell the truth or transfiguring objects into spying devices.
