There could also be new characters introduced in the fanfiction. Maybe an old wizard or witch who has knowledge about the plague bloodline and its secrets. This character could act as a mentor to Harry, guiding him through the discovery of his heritage and the powers that come with it.
Well, perhaps the plot could involve Harry discovering his plague bloodline and how it ties into the history of the wizarding world. It might be related to an ancient curse or prophecy. For example, the plague bloodline could be the key to defeating a new, powerful dark force that is emerging in the wizarding world. And as he uncovers more about it, he has to deal with the reactions of his friends and the wizarding community, some of whom might be fearful or suspicious of his new - found heritage.
Yes, there might be. The Harry Potter fandom is vast and diverse, with fans exploring all kinds of scenarios in their fanfictions. A 'Harry Potter has a plague' concept could be someone's unique take on the wizarding world, perhaps exploring how the magical community would deal with a plague, or how Harry Potter specifically would be affected. However, it may not be a very common theme compared to others like Harry's battles with Voldemort.
First, try searching on large fanfiction communities. Fanfiction.net has a huge collection of Harry Potter fanfictions. Just go to the site, enter 'Harry Potter has a plague' in the search bar. Another option is AO3. It has a more organized tagging system. Look for tags related to Harry Potter and plague. You might also want to check some Harry Potter - specific fanfiction forums where fans might discuss or share such unique fanfictions.
Obviously, Harry Potter himself is a central character. Since it's about his bloodline, he will be the one through whom the exploration of the bloodline occurs. Then there might be a new character who is a long - lost relative from the bloodline. This character could be an old wizard or witch with a wealth of knowledge about the family's past and the secrets within the bloodline.
The Ministry of Magic would likely be in chaos. They would try to find a way to stop the spread and hold Harry Potter accountable. There would be a lot of panic among the wizards and witches, with many trying to flee or find a cure on their own.
Maybe it was an accident. Harry Potter was experimenting with some dark magic (which he may have been forced into or just out of curiosity) and things got out of hand, resulting in the creation of the plague.
There could also be a plotline where the exploration of Harry's bloodline reveals a connection to a different magical culture. This could lead to interactions with new magical creatures, spells, and ways of life. For instance, his bloodline might have roots in a far - off land where magic is practiced in a completely different way, and he has to learn about and adapt to this new magical heritage.
Well, it might enhance his magical power significantly. Dragon blood is often associated with great strength and heat in magical lore. So his spells could be more powerful, like his Patronus might be larger or more vivid. Also, he could have a natural affinity for fire - related magic, being able to conjure and control flames more easily than others.
One unique trait could be his eyes. Maybe they have a dragon - like glint or change color in certain situations, like when he's using powerful magic. His sense of smell could also be heightened, similar to how dragons can detect scents from far away. This could help him in finding hidden objects or detecting danger.
