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.
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.
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.
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.
The snake might use its ability to move stealthily. It could spy on the enemies for Harry Potter. For example, it can slither into hidden places where humans can't easily reach and gather important information.
Well, in many fanfictions, Susan Bones might use her knowledge of the wizarding world's lore. Since she comes from an old wizarding family, she could share some secrets that help Harry in his fight against Voldemort. For example, she might know about some hidden magical artifacts or spells that are not well - known.
Goblins are very good at magic related to security and protection. So Harry could learn spells to protect places or objects better. He might also learn how to detect and break through different kinds of magical security measures, which would be useful in his adventures against dark wizards. He could also learn about the magic of precious stones and how to use them in different spells.
The snake's help could represent an unexpected alliance. In the Harry Potter series, snakes are often seen as symbols of Slytherin, which is usually at odds with Harry. So it's significant as it breaks the stereotype of enmity between Gryffindor (represented by Harry) and Slytherin.
Sometimes, new original characters are created in fanfiction to help Harry. These could be students from other wizarding schools who have unique skills. For example, a student from a school in a far - off land who has mastered a type of magic that is unknown in Hogwarts and uses it to help Harry in his fight against the dark forces.
