They could offer him information. Goblins often have a deep knowledge of the magical world's history and secrets, which might be crucial for Harry's journey. For example, they might know about some hidden enemies or undiscovered spells. They could also give him advice on how to deal with certain magical creatures or situations that he is unfamiliar with.
There could be a goblin named Griphook. In the original series, Griphook has some interactions with Harry, and in the fanfiction, he might play a more significant role in helping Harry.
Harry Potter is the key character as the title implies he is the one getting help. The goblins play a major role too. There could be a goblin leader, perhaps an old and wise one. Hermione and Ron may make appearances, but mainly it's about Harry's interaction with the goblins. There might also be some side characters from the goblin community, like young goblin apprentices who help Harry in unexpected ways.
In this fanfiction, a possible plot point is that the goblins help Harry in a way that challenges the traditional wizarding world's rules. For example, they might introduce him to a different kind of magic that the wizards have long forgotten. Also, the goblins could have their own motives for helping Harry, like seeking a change in their status within the magical community. This creates an interesting dynamic as Harry has to navigate between his own goals and the goblins' interests.
Another way is through training. Amelia Bones, being an experienced witch in the magical world, could train Harry in skills that he lacks. This could range from advanced defensive magic to understanding the politics within the Ministry. Such training would enhance Harry's capabilities and better prepare him for the challenges he faces.
Well, often Harry could receive financial help from Gringotts in fanfiction. Since he has his parents' inheritance there. The goblins, who are known for their strict business ethics but also a sense of fairness, might provide him with enough gold to buy rare magical items or hire the best tutors to improve his magical skills.
In many fanfictions, goblins helping Harry are often portrayed as highly intelligent and cunning. They use their knowledge of magic, especially in areas like Gringotts and ancient magical artifacts. For example, they might provide Harry with crucial information about a hidden Horcrux or a powerful magical item that could help him in his fight against Voldemort. Their portrayal also emphasizes their sense of self - interest. They'll help Harry but usually expect something in return, like a share in the treasures or a change in the wizards' treatment of goblin kind.
In some Harry Potter fanfiction, goblins might help by providing valuable magical items. For example, they could offer unique wands or enchanted artifacts that give Harry an edge in his battles against Voldemort. Goblins are known for their expertise in handling precious metals and magical objects in the original series, so in fanfiction, this knowledge could be expanded upon to assist Harry in various ways.
There are also storylines where the goblins help Harry due to a debt or an old prophecy. Maybe an ancient goblin prophecy foretells of Harry's importance, and they are obligated to help him. Or perhaps Harry unknowingly did something that earned the goblins' gratitude in the past, and now they repay him by helping him in his battles against the Dark Lord and his followers.
One possible plotline could be that Susan Bones discovers some dark secrets about her own family that are related to Voldemort's rise. She then shares this information with Harry, and together they try to find a way to stop Voldemort from using these secrets to his advantage.
One way could be through his diplomatic skills. Harry might be able to negotiate with the goblins in a very fair and respectful way. He could understand their concerns and offer solutions that benefit both parties. This would make the goblins see him as an intelligent and reliable person.
