Well, the goblins could start a revolution of sorts. If they find out Harry is abused, they might see it as a sign of the general corruption and unfairness in the wizarding world towards those without power. They could use Harry as a symbol of this oppression and start demanding changes in the way the wizarding world treats its children. This would likely lead to a lot of conflict with the wizarding authorities, but it could also bring about much - needed reforms.
You might want to check out 'Secrets Unveiled'. In this story, Draco discovers Harry's abuse by accident when he follows him to an abandoned part of the school.
They would likely be shocked and angry. The Weasleys are a kind - hearted family. They might immediately take Harry under their wing more protectively, like Molly Weasley would probably start fussing over him even more, making sure he has enough to eat and a warm place to sleep.
In some fanfictions, the Death Eaters might see Harry as a tool. If they find out he's abused, they could try to manipulate him. They might think that with his power and now his vulnerability, they can turn him to their side, using his anger at his abusers as a driving force.
Ron might also be a main character. He could be there for moral support to Harry. And his sense of humor might help ease the tension between Harry and the goblins at times. Also, he might accidentally stumble upon a clue that is crucial for helping the goblins, like finding a secret passage in a goblin - related place.
Maybe there's a young and brave goblin named Rikkit. He is not as well - known as Griphook but is eager to prove himself. He is the first to spot Harry in danger and convinces the other goblins to come to Harry's aid. His quick thinking and courage are what make the rescue possible in the first place.
One important goblin could be Griphook. He's a well - known goblin in the Harry Potter series, and in this fanfiction, he might be the main goblin responsible for Harry's healing. He has knowledge of the secrets of Gringotts and could use that knowledge to aid in the healing process.
They could face expulsion from the wizarding community if the abuse is severe enough. The wizarding world has its own laws and rules, and abusing a young wizard like Harry would be a serious offense.
They might be shocked and immediately try to offer protection. For example, they could take Harry to a safe place within the wizarding world where he can't be reached by his abusers.
