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.
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.
The theme of self - discovery is also present. As Snape deals with multiple sclerosis, he often discovers new aspects of himself, such as his own resilience. And there's also the theme of relationships changing. Some characters may distance themselves, while others draw closer, and this exploration of human connection in the face of illness is a key part of these fanfictions.
One good Snape has multiple sclerosis fanfiction is 'The Struggles of Snape' which delves deep into how he copes with the disease while still dealing with his Hogwarts duties. It's a really interesting take on his character.
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.
One inspiring multiple sclerosis story is about a woman who was diagnosed but refused to let it stop her from living her life. She started painting as a form of therapy and her works became so popular that she held exhibitions to raise awareness about MS. Another is a man who, despite his MS, completed a marathon with the help of his support team. And there's also a young girl who, through her own experience with MS, became an advocate for better research funding and patient support.
One horror story could be a young person in the prime of their life, suddenly starting to lose their ability to walk. They go from being active and independent to relying on a wheelchair in a short time. Their social life crumbles as they can't participate in activities they once loved.
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.
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.
One popular one is 'The Emperor of All Maladies: A Biography of Cancer' by Siddhartha Mukherjee. Although it's about cancer, it has a similar exploration of a life - changing illness like multiple sclerosis. Another could be 'When Breath Becomes Air' by Paul Kalanithi. It's about a doctor's own experience with a terminal illness and has themes that can be related to multiple sclerosis patients and their families.
