Some characters might have to learn to communicate with each core separately. It could be like having multiple voices in their head, each representing a different aspect of their magic.
One interesting concept could be the unique abilities that come with multiple magical cores. For example, a character might be able to perform spells from different magical traditions more easily. Another concept could be the challenges in controlling such power. With multiple cores, there might be a struggle to balance the magic within.
In Harry Potter magical core fanfiction, there are often ideas about rare magical cores. For instance, a dragon heartstring core from a very ancient and powerful dragon could be a central concept. This might give the wand wielder an edge in combat magic. There could also be fanfictions that deal with the malfunction or corruption of a magical core, leading to unforeseen and dangerous magic. Some might even create new types of magical cores based on mythical beasts not mentioned in the original series, like a basilisk fang core which could have venom - related magic abilities.
Another possibility is that it's a descendant of an ancient wizarding family. This character has been sheltered from the wizarding world until they discover their second magical core. Their family's secrets and history could be intertwined with the nature of this second core, and they have to navigate the wizarding world while also uncovering their family's past.
One interesting idea could be the exploration of a new magical power source. It might introduce unique spells or abilities related to this second magical core. For example, the character could have a different type of magic that is not found in the original series, like the ability to communicate with magical creatures in a more profound way.
One interesting concept could be how a character's altered magical core changes their spellcasting abilities. For example, if a character's core is infused with a different type of magic, they might be able to perform spells in a unique way that others can't. Another concept could be the origin of the alteration. Was it a result of a dark curse, or perhaps an experiment gone wrong? It could also lead to new relationships and power dynamics within the wizarding world as characters with altered cores might be seen as either threats or valuable assets.
Harry Potter himself is often a popular character in such fanfiction. His already - powerful magical core being altered can lead to all sorts of interesting storylines. Hermione Granger is also a favorite. Fans like to explore how her brilliant mind would deal with an altered core, whether it enhances her intelligence - related magic or gives her new challenges. Draco Malfoy is another one. Altering his core can create a whole new dynamic for his character, from his relationship with his family to his standing in the wizarding world.
You could write a fanfiction where the magical core block is a key element in a magical mystery. A group of Hogwarts students could find an ancient magical core block that seems to have some sort of hidden power or message. They then embark on a journey to unlock its secrets, facing challenges and meeting new characters along the way. It could also be interesting to explore the relationship between a wizard's personality and their magical core block in a fanfic. For instance, a particularly brave wizard might have a magical core block that glows brighter in dangerous situations.

In Harry Potter fanfiction, a large magical core changes the story in multiple ways. Firstly, it gives Harry an advantage in his magical education. He can grasp complex spells faster. Secondly, it affects his relationships. His friends might feel a bit overshadowed, but also proud of him. And in battles, he becomes a key player much earlier than in the original story. His large core can also attract unwanted attention from dark wizards who see him as a threat.
