The main character is the healer, who may have a group of friends or colleagues also involved in the healing arts. They could be from different houses at Hogwarts. There might be a character who is initially skeptical of the healer's unorthodox methods but later comes to respect them. And we can't forget about the magical creatures. There could be a centaur or a house - elf that the healer befriends and who helps them in their quests related to healing in the wizarding world.
Most likely, the main character is the healer. They could be an original character created for the fanfic. There might also be appearances from well - known Harry Potter characters like Harry himself, Hermione, and Ron. Maybe the healer has to work with them to solve some sort of magical health crisis in Hogwarts or the wizarding world at large.
In this fanfic, the healer is surely a central figure. There could be a mentor figure, perhaps an older and more experienced healer who guides the main healer. Additionally, there might be antagonists. For example, a dark wizard who wants to disrupt the healer's work or steal their knowledge of healing magic for their own malicious purposes. And of course, we can expect to see some of the Hogwarts professors as they are an integral part of the wizarding community and would interact with the healer.
Harry is the central figure, of course. However, some fanfictions might introduce new characters. For example, a young Muggle - born witch or wizard who Harry takes under his wing to teach about magic and healing. There could also be a former Death Eater who has reformed and now wants to learn the ways of healing from Harry to atone for their past sins.
Neville Longbottom could also be considered a natural healer. He has a great affinity for Herbology. His skills in growing and understanding plants could easily translate into using them for healing. He could be the one to discover new uses for common and rare magical plants alike, perhaps creating poultices or potions from them to heal various ailments that the regular wizarding medical field hasn't fully explored yet.
A healer Harry Potter fanfic can be unique because it can introduce new characters who are healers. These characters may have different backgrounds, like coming from a family of non - magical healers but having magical abilities. It also might explore new areas in St. Mungo's or new healing spells that are not in the main series. This creates a whole new aspect of the wizarding world to explore.
Luna Lovegood is sometimes written as a mind healer in fanfiction. Her unique perspective and kind heart make her a great candidate. She can use her understanding of thestrals and other magical creatures to bring comfort to those with troubled minds.
The healer themselves would obviously be a main character. They could be a young and inexperienced healer, full of enthusiasm but also a bit naive. This would make for an interesting character arc as they grow and learn throughout the story.
It could be a Muggle - born protega. This character would face unique challenges as they try to protect the wizarding world while also dealing with their own identity issues. They might have friends among the Hogwarts students, and together they form a group to counter a new evil force that targets both Muggles and wizards.
Obviously, Harry Potter would be one of the main characters. He's the hero of the original series and would likely play a central role in any fanfic about the basilisk. Hermione Granger would probably also be there, using her intelligence to help solve the problems related to the basilisk.
I don't know for sure as I haven't read this particular fanfic. But if it follows the general 'Harry Potter' lore, it could be Harry, Hermione, and Ron. They are often central characters in many fanfics and could be involved in whatever 'purge' is taking place in this story.
Without reading it, it's hard to say. But it could feature the main characters from the original series like Harry, Hermione, and Ron as they are usually central in most Harry Potter fanfics. They might be the ones trying to solve the conundrum.
It could be Harry Potter himself still being a main character. He might be the one exploring the combination of magic and nen. Hermione would also likely be there, using her intelligence to figure out how nen works in the wizarding world. Ron might be involved too, perhaps struggling a bit more to adapt to the new nen concepts compared to the others.
