It could be an old and wise goblin who has been in Gringotts for centuries. He has seen many things and has a vast knowledge of the magical items stored in the vaults. When the call for a champion arises, he steps forward, not for glory but to protect the integrity of Gringotts. He would be a character full of mystery, with his own motives and secrets that unfold as the story progresses. He might have a complex relationship with the wizarding world outside of Gringotts.
A possible main character could be a half - blood wizard who works at Gringotts as a security guard. He is caught between the two worlds of wizards and goblins. When he is named the Gringotts champion, he has to navigate the politics within Gringotts as well as deal with the outside threats. He is a character who is constantly underestimated but has a strong sense of justice and loyalty, which helps him in his journey as the champion.
The main character could be a young Gringotts trainee who has always been overlooked but has a hidden talent for magic related to the vaults. Maybe they can sense the magical auras of different vaults and their contents, which is a rare ability. This character gets chosen as the champion unexpectedly and has to rise to the challenges that come their way, learning about their own power and the secrets of Gringotts along the way.
A plot could involve a competition among different Gringotts employees to become the 'Gringotts Champion'. The winner would get a special privilege, like access to a long - sealed vault that is rumored to hold great power. A young and ambitious wizard working at Gringotts decides to enter the competition. He discovers that there are dark forces at work trying to rig the competition in their favor. With the help of Harry Potter, who he meets by chance, they expose the conspiracy and ensure a fair competition.
The main characters typically include the champion, who is at the center of the story. This might be a young wizard or witch with unique abilities. Then there are the goblins. They are crucial as they control and protect Gringotts. In some fanfictions, characters like Harry Potter, Hermione Granger, or Ron Weasley may also make appearances, either as friends or mentors to the champion. Additionally, there could be antagonists such as dark wizards who want to break into Gringotts and steal its treasures.
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.
It could be Neville Longbottom. He has the potential to be a supreme champion. He grew a lot throughout the series, and in fanfiction, he could be given more opportunities to shine and show his true power and skills, becoming the supreme champion.
It could be a powerful dark wizard who has a grudge against the goblins and wants to destroy Gringotts. This wizard might have been wronged by the goblins in the past, and now he's seeking revenge by trying to bring down the bank. He could be using his own army of dark creatures to attack Gringotts.
The goblin elders who oppose Harry's new - found ownership could be the main antagonists. They might be worried about losing their power and influence within Gringotts to a human, especially one as famous as Harry Potter.
The goblins themselves could be the main antagonists. They are in charge of Gringotts and if they are greedy and corrupt, they would oppose any attempts by Harry to expose their wrongdoings that could lead to the bank's bankruptcy. They might try to stop Harry by using their magical skills and the defenses of the bank.
It could be a character from a different wizarding school that we haven't heard of before. Maybe a student from a school in a far - off land like the Americas or Asia. They would bring in different magical traditions and skills.
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.
It could be a new character, perhaps a young witch or wizard who has just received their Hogwarts letter and then discovers this inheritance. This would be an exciting start to their magical journey.
