Unbreakable Vow in Harry Potter Fanfic: What Are Some Creative Interpretations?

In the original series, the Unbreakable Vow is a very serious and rarely used magical bond. In fanfic, it can be more common. For instance, in fanfic authors might use it more often to drive the plot forward. They might have characters enter into the vow more casually (compared to the original where it was a big deal).

One creative interpretation could be that the tentacles belong to a new magical creature that has been discovered in the Forbidden Forest. This creature could be both friendly and helpful, using its tentacles to perform tasks like gathering herbs or helping lost students find their way back to the castle.

A really interesting take on the first task in a fanfic could be that Harry uses a completely different strategy. He doesn't use his Firebolt or any of the spells we expect. Instead, he uses his Parseltongue ability to communicate with the dragon, convincing it to let him take the egg without a fight. This would show a new side of Harry's power and his ability to think outside the box.

One common interpretation is that ghouls in Harry Potter fanfics are often depicted as more intelligent and sentient than in the original books. They might be given backstories that explain their existence in the wizarding world in more detail, perhaps as a result of dark magic gone wrong.

One possible storyline could be Sky Harry discovers a hidden magic within Hogwarts that no one else knew about. Maybe it's a secret chamber that holds the key to an ancient magic that can defeat the darkest of dark wizards. Another could be Sky Harry having the ability to communicate with magical creatures in a unique way, leading to him forming an alliance with them to protect the wizarding world. And he might also have a special connection to the stars (sky), which gives him extra powers during certain celestial events.

Perhaps it's part of a bet or a dare within the Gryffindor common room. Harry loses a bet and has to endure wearing a pair of enchanted panties for a day, which leads to all sorts of humorous adventures as he tries to go about his normal school day without getting caught or causing too much chaos.

One idea could be to create a Marauder's Map - inspired invitation. Write the promposal message on a piece of parchment that looks like the map, with little footprints leading to the words asking the person to prom. Another could be to use a Sorting Hat. Get a fake Sorting Hat and have it 'Sort' the person into the 'Prom with Me' category.

One way is to base the name on a specific location in the wizarding world. For instance, if your story takes place a lot in Diagon Alley, you could name it 'Diagon Alley Adventures: A Harry Potter Fanfic'.

In some fanfics, Fair Fortune could be related to the concept of fate. It might be a power that guides certain characters to their destined roles. Maybe it's the reason why a seemingly ordinary wizard suddenly rises to great importance. It's like an unseen hand that shapes the story in ways that are both magical and mysterious.

An MPD (Multiple Personality Disorder) OC (Original Character) in a Harry Potter fanfic could be really interesting. For example, an OC with MPD might have one personality that is a brilliant spell - caster, while another is more attuned to magical creatures. This could create unique storylines within the wizarding world. They could struggle with their different personalities in Hogwarts classes, like in Potions when one personality is confident and the other is shy and hesitant.
