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.
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.
Creatively, Gringotts can be a place of cultural exchange. Since it's a bank that serves both wizards and other magical creatures, it can be a place where different magical cultures interact. In a fanfic, Harry could witness a meeting between a goblin banker and a centaur who is trying to deposit some rare magical herbs as collateral for a loan. This could lead to all sorts of interesting storylines about cultural differences, misunderstandings and cooperation within the magical world.
One popular fanfiction idea could be a story where the Gringotts dragon escapes and forms an unlikely alliance with a young wizard or witch. They might go on adventures together, facing the wrath of the goblins who want their dragon back.
In this fanfiction, perhaps it's not just physical protection. Gringotts could be protecting Harry Potter in a more symbolic or magical sense as well. They might be guarding his family's legacy, which is tied to certain items or secrets in the vaults. This could lead to a whole series of adventures where Harry has to work with the goblins to uncover his true heritage and at the same time, stay alive while being protected by the might of Gringotts.
In some fanfictions, Harry Potter might help Gringotts by using his fame and influence. For example, if there's a threat to the bank's security or reputation, Harry's name could be used to deter villains. His status as the 'Boy Who Lived' makes him a well - known figure in the wizarding world, and his association with Gringotts could bring in more business or protection.
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.
One challenge would be the goblins. They are very protective of Gringotts and would not easily give up control. They have their own laws and traditions regarding ownership. Harry would have to deal with their resistance and find a way to convince them or negotiate with them.
Maybe Harry gets assigned to a special project at Gringotts. For example, to help relocate a very dangerous magical item from one vault to another. Along the way, he has to face various challenges like magical traps and other creatures that guard the vaults. This could lead to a series of adventures as he tries to complete the task.
Well, if Harry Potter worked for Gringotts in fanfiction, he'd probably have a whole new set of challenges. First of all, he'd have to learn the ins and outs of the goblin - run bank. He might be given the task of guarding some of the most valuable vaults. This could put him in the middle of some power struggles between different wizarding families who all want access to their family treasures. Also, he could use his knowledge of the wizarding world from Hogwarts to improve security at Gringotts, or perhaps he'd uncover some illegal activities within the bank that he'd then have to stop.
