There's a fanfic titled 'Goblin Guardians'. In it, the goblins, seeing Harry's potential and the injustice he faces, decide to help him. They provide him with ancient magical artifacts and train him in combat techniques that are different from what he learns at Hogwarts. This gives Harry an edge in his fight against the dark forces.
Another theme is the exploration of goblin magic and culture. When they help Harry, it often involves sharing their unique magical knowledge and traditions. This can include things like their methods of forging magical items which are far more advanced than what the wizards usually do. In some fics, Harry learns from the goblins how to use magic in a more instinctive and powerful way based on goblin magic principles.
In some fanfictions, the goblins could assist Harry in learning about his family's true history and the secrets they left behind. This might involve them taking him to secret places within Gringotts that are not known to most wizards. The goblins' skills in deciphering ancient runes and their understanding of the magical economy could play a big role in this. For example, they could reveal that there are certain magical items that his family had stored away for a time of great need, and these items could give Harry an edge in his battles.
There is a 'Harry Raised by Goblins Fanfic' that I really like. It's called 'Among the Goblins'. In this fanfic, Harry is raised in the goblin society. The story delves deep into the goblin culture, their traditions, and how Harry adapts to it. It also shows how his new upbringing affects his relationships with the characters from the original Harry Potter series. For example, his view of Dumbledore and the Ministry of Magic is very different from what it would have been if he had been raised as a normal wizard. It's a really fascinating read if you're into this type of fanfic.
In most well - written fanfics, Harry is polite to the goblins. The goblins are an important part of the wizarding world, and Harry, being the kind - hearted character he is, would likely extend his courtesy to them. His politeness can also be a strategic move in some fanfics, as he may need the goblins' help for various reasons, such as getting access to his vault at Gringotts or seeking information about certain magical artifacts. This polite attitude towards the goblins helps to build relationships and move the plot forward in these fan - created stories.
Griphook is often an important character. In the original books, he had a significant role in relation to Gringotts, and in fanfiction, he could be the main goblin helping Harry. He might use his knowledge of the bank's secrets and security to protect Harry or lead him to valuable things.
He might use formal greetings when he meets them at Gringotts. For example, he could say 'Good day' in a respectful tone.
A really cool Harry Goblins fanfic could be set in an alternate universe where Harry is raised by goblins. This would completely change his perspective and abilities. He might have a different understanding of magic, more in line with the goblin way, and have to face the challenges of being a half - human in a goblin - dominated society.
Goblins can be shown as highly intelligent and skilled in craftsmanship. For example, in a fanfic, they could be the ones creating the most complex and powerful magical items, like the Elder Wand. Their pride in their work could be a big part of their character.
One popular 'Harry is helped by deities' fanfiction is 'Divine Intervention in Hogwarts'. It shows how different deities from various mythologies come to Harry's aid during his toughest battles at Hogwarts.
I'm not sure of the exact name, but I've read a fanfic where goblins were helpful in rebuilding Hogwarts after the war. They used their magic and engineering skills to restore the damaged parts of the castle. They also taught the students about the history of the castle's construction and the magic used in it, which was really interesting.
