What are some interesting plot ideas for a 'Harry Potter, Head Goblin of Gringotts' fanfiction?

One idea could be a story where a young wizard discovers a long - forgotten vault in Gringotts that holds the key to an ancient magic. Maybe it's a magic that was lost during the time of the founders of Hogwarts. Another plot could involve a heist at Gringotts, not by the main characters like in the original series, but by a group of dark wizards who are after a powerful and dangerous artifact. A third idea is that a character gets trapped in the deeper, more mysterious levels of Gringotts and has to find their way out while uncovering secrets about the wizarding bank's history.

Voldemort or his Death Eaters could be antagonists. They might want to raid Gringotts to get powerful magical artifacts or gold to fund their dark deeds. Another option could be a group of corrupt wizards within the Ministry of Magic who see Gringotts as a source of wealth and power that they can control. They could try to undermine the Head Goblin and Harry Potter if they stand in their way.

One idea could be a story where a young wizard loses his Harry Potter - style robes near Gringotts. He then has to go on a mini - adventure to find them before an important wizarding event. Maybe he discovers a secret passageway while looking for his robes that leads to a hidden vault in Gringotts.

One interesting plot idea could be a crossover where a character from another fandom accidentally stumbles into Gringotts in the Harry Potter world. Maybe a time - traveling character who has to figure out how to navigate the wizarding bank's security and magical vaults without getting caught. Another could be a scenario where the goblins of Gringotts have a secret alliance with a group from another universe and Harry Potter and his friends have to uncover this plot that could potentially disrupt the wizarding economy. A third idea might be that a character from a different story has a special key or artifact that unlocks a long - forgotten and extremely powerful vault in Gringotts, leading to a race between the good and bad forces in the Harry Potter world to obtain what's inside.

A really interesting plot could be that a goblin mate has a unique magical ability that is the key to saving Hogwarts from a new dark threat. The wizarding characters initially doubt the goblin but gradually come to realize their importance and the power of their bond.

A great plot could be that the goblin is a time - traveler. It has come from a future where Voldemort has won and is trying to change the past. The goblin teams up with Harry, using its unique goblin magic and knowledge of the future to give Harry an edge in the fight against the dark forces. They might have to travel to different magical locations and enlist the help of other magical creatures.

One idea could be that Harry discovers a long - lost vault that contains a powerful and dangerous magical artifact. He has to figure out how to deal with it without causing chaos in the wizarding world. Another is that he uncovers a conspiracy among some of the Gringotts employees to steal from the vaults of important wizarding families.

Maybe a fanfic where the goblins of Gringotts go on strike. Since Harry has some influence with them due to his own vault and his adventures there, he gets involved in the negotiations. Along the way, he uncovers a plot by some Death Eaters who are trying to take advantage of the chaos to steal valuable magical artifacts from the bank. It would be a mix of politics, mystery and action.

One idea could be a head of house having to deal with a new and dangerous dark magic threat within their own house. Maybe the head of Gryffindor discovers that some students have been dabbling in a forbidden spellbook. Another could be a head of house trying to organize an inter - house tournament to boost morale and unity among the students, but facing opposition from other heads of house who think it's too risky. And a third idea might be a head of house uncovering a long - lost secret about their house's founder that changes the way they view their role and the traditions of the house.

One idea could be that the Head Boy has to deal with a secret society within Hogwarts that is causing chaos. Maybe they are trying to bring back an old dark magic spell. Another could be that the Head Boy discovers a hidden room in Hogwarts that holds the key to an ancient mystery related to the founders of the school. He then has to protect this secret from those who might misuse it.
