A possible plot could be that the soul bond is initially a mystery to them. They start having strange dreams about each other and gradually realize there's a connection. As they explore the bond, they find that it also makes them targets. Dark wizards want to use the power of their bond for evil purposes, so they have to fight to protect themselves and the bond.
Perhaps the soul bond is a key to a hidden magic. They discover that together they can unlock ancient spells or access a secret part of the wizarding world. They then have to go on a quest to figure out what this all means and how it relates to the greater good of the wizarding community. It could involve facing many challenges and relying on their unique bond to get through them.
Perhaps the soul bond is discovered during a time of great turmoil in the wizarding world. Hermione and Lucius find themselves in a situation where they must work together to protect something important, like an ancient magical artifact that could tip the balance of power. The bond makes their partnership more intense and complex, as they have to deal with their own personal feelings and the expectations of their respective sides. Along the way, they might develop a grudging respect for each other that could potentially turn into something more, like a friendship or even a romantic relationship, which would shock their friends and foes alike.
Well, Hermione is very studious and Sirius is quite rebellious. The soul bond could make Hermione a bit more adventurous. For example, she might be more willing to break some minor rules because she can feel Sirius's disregard for overly strict regulations. And Sirius might become more interested in learning, influenced by Hermione's love for knowledge.
Another plot could be set in an alternate universe where Sirius never went to Azkaban. He and Hermione meet when she is a young, brilliant witch just starting at Hogwarts. Sirius, being a bit of a rebel, takes Hermione under his wing and they embark on adventures outside of the school rules, exploring the Forbidden Forest together and uncovering secrets about the wizarding world that are not taught in classes.
One plot idea could be Hermione discovering her true parentage through a series of magical events. Maybe she stumbles upon an old family heirloom that has a connection to Sirius. Another could be her having to deal with the reactions of her friends, like Harry and Ron, who are shocked by this revelation. She might also face challenges within the wizarding community as Sirius had a somewhat controversial past.
A possible plot is that Hermione discovers some long - lost secrets about her father, Sirius. This could lead her on a quest to uncover the truth about his past and his family. Along the way, she might find out about some hidden magical artifacts or spells that were associated with Sirius's family line. It could also involve her interacting with Sirius's old friends and enemies, which would create a lot of interesting dynamics. For instance, she might have to deal with some who are still bitter about Sirius or others who want to protect his legacy through her.
One idea could be that the daughter inherits Hermione's intelligence and Sirius's rebellious spirit. She might use her smarts to uncover secrets about the wizarding world that were long buried, like hidden spells or lost histories. Another plot could involve her struggling to fit in at Hogwarts, being the daughter of two such well - known figures. She could face both envy and admiration from her peers.
There's a fanfic called 'Sirius and Hermione's Unbreakable Bond'. It starts with Sirius seeing Hermione's potential from the very beginning. He becomes a mentor to her, which is different from their normal Hogwarts interactions. The story delves deep into how their different experiences in the wizarding world bring them closer. Hermione's intelligence and Sirius' rebellious spirit create a unique dynamic between them.
Maybe the mind bond is formed during a dangerous magical experiment gone wrong. As a result, Hermione and Snape have to constantly share thoughts and feelings. This forces them to work together despite their initial animosity. Snape might find Hermione's thirst for knowledge and quick thinking surprisingly endearing, and Hermione could see the deep loyalty and hidden kindness in Snape.
Well, perhaps there's a fanfiction where Sirius Black is wrongly accused again, but this time Hermione believes in his innocence from the start. She uses her intelligence and resources to prove his innocence while they are on the run from the Ministry. Along the way, they form a deep bond and discover new magical abilities within themselves that they use to clear Sirius' name and also make some changes to the wizarding world's justice system.
A great plot idea would be that when they time travel, they accidentally change something in the past that has a huge ripple effect on the future. They then have to figure out a way to fix it. Maybe they make it so that Sirius was never disowned by his family in the past, which changes his whole life trajectory. This could lead to a completely different future for the wizarding world, and they have to race against time (again) to make sure the future doesn't go completely haywire.
