Goblins are essential characters in Gringotts - related fanfiction. They are the ones who run the bank and have their own set of rules and personalities. Some fanfictions might introduce new goblin characters with unique traits. And then there are the dark wizards or witches who could be trying to break into Gringotts for their own nefarious purposes, like Bellatrix Lestrange who had an interest in the Lestrange vault.
Hermione Granger could also be a common character. Her intelligence and thirst for knowledge make her a great fit for exploring the secrets of Gringotts inheritances. She might be the one to figure out the clues and riddles associated with an inheritance, helping her friends or even herself if she were to be the heir in the fanfiction.
Obviously, Harry Potter himself can be a common character. Since he has a connection to Gringotts through his own vault and his family's history, he might be involved in stories about inheritances. Hermione Granger could also be there, using her vast knowledge to help decipher the mysteries of the inheritances. And the goblins of Gringotts are always present as they are the keepers of the vaults and the ones who enforce the rules regarding inheritances.
The goblins are also main characters in many such fanfictions. They have a deep connection to Gringotts and are natural defenders. Their unique magic and understanding of the bank's layout and security make them crucial in any defense. And of course, there could be some descendants of Harry Potter's friends, like a young Gryffindor who feels it's their duty to protect the bank just like Harry protected Hogwarts.
Obviously, Harry Potter would be one of the main characters. And the goblins of Gringotts, like Griphook, would also play a major role as they are the ones doing the protecting.
It could be a young goblin who has just started working at Gringotts. He's full of enthusiasm but also a bit naive. Through his eyes, we can see the inner workings of the bank, the different vaults, and the various magical items stored there. Another option could be an older wizard who has a long - standing debt with Gringotts and is trying to find a way to pay it off without sacrificing his most precious magical possessions. Or perhaps a young witch who is an expert in ancient runes and is called in by Gringotts to help decipher some mysterious inscriptions found in one of the oldest vaults.
Obviously, Harry Potter would be the main character as it's in the title. But we might also see other familiar faces like Hermione and Ron. They could be helping Harry in his new role as the King of Gringotts. And of course, there would be goblin characters like Griphook who would play important roles as they are closely associated with the bank.
Hermione might also be a main character. Her intelligence and knowledge of magic would be invaluable in dealing with whatever the weapon in Gringotts is. She could be the one to figure out how to unlock the secrets surrounding the weapon, like deciphering ancient runes or understanding complex magical texts related to it.
One possible implication could be that Harry has access to unlimited wealth and resources. This would change his status significantly within the wizarding world. He could use the gold to fund various projects, like improving Hogwarts or helping out the less fortunate wizarding families.
Well, for sure Harry Potter is a top pick. His connection to Gringotts started early on when he first visited to get his inheritance. Hermione would be there as she's the brains of the group and would be curious about any magical lore associated with Gringotts. Ron, with his family's financial struggles, could also play an important role. The goblin bankers are a given as they are the heart of Gringotts. In terms of crossover characters, if it was a crossover with 'Alice in Wonderland', the Cheshire Cat could make an appearance. It could be lured by the shiny objects in Gringotts and cause some chaos as it tries to steal something, with Harry and his friends having to stop it.
It could also be a strategic move. Gringotts is a highly secure place. By buying it, Harry could ensure the safety of important magical artifacts or secrets. He could use it as a base to store and protect things that are crucial for the future of the wizarding world, like ancient spells or prophecies.
