The main characters would be the Goblin Prince and Harry Potter. The Goblin Prince with his own goals and background within the goblin society. Harry Potter, on the other hand, brings the perspective of the wizard world. There could also be a female goblin character who is either a love interest of the Goblin Prince or a powerful ally. And some dark wizards or antagonists who oppose the Goblin Prince's plans could also be considered main characters in terms of driving the conflict in the story.
Obviously, the Goblin Prince would be one of the main characters. Harry Potter would also be a central figure. There might also be other characters like Hermione and Ron who could get involved in the story, perhaps as they try to understand the motives and actions of the Goblin Prince. And of course, there could be various goblin characters who are part of the Goblin Prince's court or family.
It's hard to say without reading it, but it could be Harry Potter himself. Since it's set in the Harry Potter universe, he might be involved in the goblin - related surprise. Maybe Hermione and Ron could also be part of it, as they are usually by Harry's side in most adventures.
Harry Potter is the obvious main character. The goblin would be another main character. In addition, there could be a wizard or witch who is either helping or hindering Harry and the goblin in their adventures involving the lemon. Maybe it's a teacher from Hogwarts who has some knowledge about the goblin - lemon connection.
Some fanfictions create entirely new goblin characters. For example, there could be a young goblin prodigy who befriends Harry. This character could have extraordinary skills in metal - working magic, which is something goblins are known for in the Potterverse. They might use their skills to create powerful magical items for Harry or help him in his battles.
Obviously, Harry Potter would be one of the main characters. And Griphook, the goblin we know from the books, could also be a main character as he has prior interactions with Harry. Another could be a young, rebellious goblin who wants to change the relationship between goblins and wizards and is the driving force behind the alliance.
One main character could be Griphook. He already has a complex relationship with Harry Potter in the original series. In a goblin rebellion fanfiction, he could be a key figure leading the goblin revolt, using his knowledge of the wizarding world and his own skills to strategize against the wizards. Another character could be a young goblin apprentice who is caught between his loyalty to his own kind and his admiration for Harry Potter and the wizarding world.
Well, Harry Potter himself might be a main character in some fanfictions. He could be the one interacting with the goblin mate, perhaps learning about goblin culture through this relationship.
Obviously, Harry Potter would be one of the main characters. And there would be goblins, perhaps Griphook who is a well - known goblin in the Harry Potter series. Since it's about him being the son of goblin friends, there might be some older goblin characters who were friends with his family. Also, his friends from Hogwarts like Hermione and Ron could be involved as they often accompany Harry in his adventures.
Some fanfictions might have a plot where the Goblin Prince has a prophecy related to him that involves Harry Potter. This could lead to a journey where they have to work together to fulfill or prevent the prophecy. The Goblin Prince could also be on a quest to retrieve a powerful goblin artifact that was stolen by wizards long ago, and Harry Potter becomes an unexpected ally in this dangerous adventure.
In fanfiction, goblins can help in various ways. For example, they might assist Harry Potter with getting access to certain Gringotts vaults that hold crucial items or information. Goblins are known for their skill in handling gold and guarding treasures, so they could use their knowledge to help Harry in his fight against Voldemort by providing him with financial resources or magical artifacts that were previously hidden away.
Obviously, Harry Potter would be one of the main characters. And there would probably be some Atlantian characters like the King or Queen of Atlantis, or other important Atlantian figures. Maybe some of Harry's friends from Hogwarts could also be involved, like Hermione and Ron, if they also get dragged into the Atlantis adventure.
