Well, in fanfiction, they usually involve some sort of exchange. The person making the contract gives something (like their soul or a great service) in return for power, knowledge, or protection. For example, a wizard might offer his soul to a demon in exchange for the ability to defeat Voldemort.
In most cases, a demon contract in Harry Potter fanfiction has specific terms. These terms are often magically binding. It could be that the contract is sealed with a special spell or ritual. Once the contract is made, the person is bound to fulfill their part. If they don't, there are usually severe consequences, like a curse or the loss of their magic. The power gained from the contract can be used for good or evil, depending on the character's intentions.
In Harry Potter fanfiction, demon contracts can work in complex ways. Firstly, there's the negotiation phase where the character and the demon (or the entity representing the demon) discuss what each side will get. Then comes the signing or sealing of the contract. After that, the effects start to take place. The power from the contract might not be immediate. It could grow over time. And the character has to constantly be aware of the terms because the demons in these fictions are often very cunning and will try to trick the character into breaking the contract so they can claim their due.
Demon magic in these fanfictions usually has a corrupting influence. It could work by tapping into the dark energies of a demonic realm. The caster may have to perform elaborate and often cruel rituals. For instance, they might need to use the blood of magical creatures or the souls of the damned. This magic is not like the normal magic in the Harry Potter world. It defies the laws of normal magic and often has unpredictable and dangerous consequences. It can also gradually corrupt the caster's mind and body, making them more and more like the demons they are drawing power from.
First, know the 'Harry Potter' universe well. Understand the magic system, the characters' personalities, and the existing rules. For the contracts part, make them logical within the wizarding world. For example, a contract about a forbidden spell should have severe consequences. Second, create interesting plot twists related to the contracts. Maybe a contract is not what it seems at first.
Well, in many such fanfictions, the marriage contract is used as a plot device to introduce new conflicts and relationships. For example, it might bring her into contact with characters she wouldn't normally interact with. This can lead to interesting character development, like her learning about different wizarding families through the contract negotiations. And sometimes, it can also be a source of comedy when she tries to wriggle out of it in a very Harry - like way.
In this kind of fanfiction, the magic system often gets tweaked. For demon familiars, they might draw on a different source of magic compared to normal familiars. It could be a darker, more primal magic. Spells used to control or communicate with them might be more complex and involve chanting in ancient languages that are associated with demons. For example, a wizard might need to use a spell with a Latin incantation that has roots in demonology to make the demon familiar perform a certain task.
Some characters rebel. For example, Hermione might use her intelligence and knowledge of magic to find loopholes in the contract. She could be very vocal about her opposition to the archaic practice. Others, like Harry, might initially feel pressured but then try to communicate with the other party involved. They might try to come to an understanding and find a way to make the situation more bearable.
Well, arranged marriages in Harry Potter fanfictions can be quite complex. Sometimes it's the wizarding government or a powerful family that arranges the marriage. The characters involved have to deal with their own feelings, their friends' reactions, and the expectations of the wizarding society. For instance, if Hermione was arranged to marry a pure - blood wizard, she'd have to balance her Muggle - born identity and her new role. It also can lead to alliances between different wizarding groups, just like in real - world history where marriages were used for political and diplomatic reasons.
Another theme is secrecy and discovery. The nature of magical contracts can be mysterious, and characters may discover hidden clauses or implications. This adds an element of mystery and intrigue to the stories. For example, a character might find out that a contract they thought was simple has far - reaching consequences. Also, loyalty is often a theme. Contracts can test the loyalty of characters to each other or to a cause, and how they deal with that loyalty in the face of the contract's demands.
There could be a fanfiction where Harry Potter enters into a contract with a powerful magical creature. In this story, the contract might involve him protecting the creature's lair in exchange for a powerful magical item. This would create a unique bond between Harry and the creature and lead to many adventures as he tries to uphold his end of the deal.
In these fanfictions, love potions often work in a similar way as in the original series, creating an artificial infatuation. But when combined with time travel, their effects can be more complex. For example, if a character from the past is affected by a love potion from the future, they might not understand the strange feelings they have.
In most fanfictions, love spells work by using a combination of magic words and ingredients. For example, it might require a certain type of flower that represents love, like a rose, and then specific incantations. The spell caster has to have a certain level of magical ability and concentration. If not done correctly, the spell could have unexpected and often humorous results.
