Are there any interesting dwarf characters in Harry Potter fanfiction?

Sure. There's a dwarf named Gimli (not from the original LOTR Gimli but in this fanfic context). He's a brilliant potions maker in the Harry Potter world. His dwarven knowledge of herbs and minerals gives him an edge in creating unique potions that even Snape is impressed with.

There could be. Since it's fanfiction, the author might introduce new characters related to the concept of soulfire. For instance, a mysterious old wizard who is an expert on soulfire and guides the main characters. Or a young witch who has an innate connection to soulfire and uses it in unique ways to solve problems in the wizarding world.

Since it's fanfiction, the author could introduce some really unique characters. There might be a magical creature living in or near the birch. Maybe a sprite or a small fairy - like being that befriends Harry and helps him in his adventure related to the birch.

One great 'Harry Potter dwarf fanfiction' could be 'The Dwarven Wizard in Hogwarts'. It's about a dwarf who discovers he has magical abilities and enrolls at Hogwarts. He faces challenges due to his different culture and size but overcomes them with his unique dwarven skills.

Yes, there might be. There could be a character who is a sun - mage, having the ability to control the power of the sun. This character could be a new ally or a mysterious figure that Harry and his friends encounter.

There might be. If Harry is the son of Erebus, perhaps there are new characters related to Erebus' side of the story. Maybe some dark entities that are either trying to help or harm Harry because of his connection to Erebus.

Since it's fanfiction, there could be new characters created specifically for this story. Maybe a healer who has a special knowledge of the blacklight virus and its effects on magic. Or perhaps a character who is somehow immune to the virus and becomes crucial in the fight against it.

Definitely. There could be a character who is a rival claimant to the heirship. They might be a descendant of one of Harry's enemies and are trying to disrupt the test. Also, there could be a magical creature that is crucial to the heir test, like a phoenix that guides the true heir through the various challenges of the test.

Yes, of course. Besides Harry Potter himself, there might be new characters created specifically for this fanfiction. For example, there could be a mentor - like figure who knows about Harry's 'Son of Doomsday' identity and helps him understand his powers. Or there could be antagonists who want to use Harry's power for their own evil purposes, like a dark wizard who believes that by controlling Harry, he can bring about the doomsday and reshape the wizarding world according to his own desires.

Well, apart from the obvious of Harry himself having a different personality due to his new parentage, there could be new teachers at Hogwarts. They might be there to guide Harry in understanding his connection to Rhea. Or perhaps there are some dark characters who are after Harry because of his unique heritage. These new characters would add more depth and complexity to the story, making it more than just a simple re - imagining of the Harry Potter series.
