Another interesting aspect could be the origin of such wands. Maybe they are created by a very powerful and ancient wizard who was experimenting with combining different magical essences. This could lead to a whole new set of wandlore and traditions within the fanfiction world.
The relationship between wizards and their wands might be different. A wizard with a multiple - core wand might have to develop a more complex bond with it, as each core could have its own personality or magical trait.
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.
In the world of Harry Potter fanfiction, wand cores can be quite creative. One type that might show up is the hair of a hippogriff. Hippogriffs are proud and noble creatures, so a wand with their hair as a core could have a certain grace and strength. There are also those that might use the scales of a mermaid. This could give the wand a connection to water magic, perhaps having special abilities when it comes to spells related to water or the sea.
Another plotline could be that Harry's multiple sclerosis actually gives him some unique magical abilities or insights. It could be that his condition makes him more in tune with certain types of magic that others can't access. This could change the power dynamics in the wizarding world and make Harry a target for some while a hero for others who see the potential in his new - found abilities.
A Thestral could also be a familiar for Harry. Since he can see Thestrals, it makes sense in the context of fanfiction. Thestrals could provide a unique form of transportation for Harry and also have some special abilities related to the afterlife or death magic that could be explored in the story.
There are many wand cores in Harry Potter fanfic. One interesting core that might be used is the scale of a mermaid. This could potentially give a wand some water - related magic abilities. Also, the fang of a werewolf could be a core, which might make the wand more attuned to lunar magic or have a wilder, more uncontrollable aspect to its magic. The idea of different wand cores in fanfic allows for a lot of creativity and exploration of new magical concepts.
In many Harry Potter fanfics, the concept of dementors often adds a dark and mysterious element. When it comes to wand cores, there could be a fanfic where a character discovers a new type of wand core that has been affected by dementor magic. This could lead to a whole new set of spells and abilities for the wizard or witch who wields it. The wand might have an affinity for dark arts - like spells, but also might be able to counteract the effects of dementors on a person's soul, creating a very complex and morally ambiguous magical item.
Well, another option is to reach out to Harry Potter fanfiction groups on platforms like Facebook. These groups often have members who are well - versed in different types of fanfiction. They may be able to point you in the right direction. It's also possible that this is a relatively rare concept in fanfiction, so you might not find a large number of stories, but with some diligent searching, you could stumble upon some real gems.
One popular 'Harry Potter has multiple familiars' fanfiction is 'The Familiars of Harry Potter' on FanFiction.net. It explores how Harry discovers and bonds with different magical creatures as his familiars in a very interesting way.
