In the world of Harry Potter fanfiction, Harry might need help in various ways. For example, he could need help dealing with a new dark wizard threat that the original books didn't cover. Maybe he's struggling with his post - war trauma and needs the support of his friends more than ever. Another possibility is that he's in a situation where he has to learn a new and difficult magic spell to save someone he loves, but he can't seem to master it on his own.
In fanfiction, goblins can help in various ways. For example, they might assist Harry Potter with getting access to certain Gringotts vaults that hold crucial items or information. Goblins are known for their skill in handling gold and guarding treasures, so they could use their knowledge to help Harry in his fight against Voldemort by providing him with financial resources or magical artifacts that were previously hidden away.
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.
His friends from Hogwarts, like Ron and Hermione, are likely to help. Ron could bring his family's practical knowledge of wizarding homes and Hermione would contribute with her extensive research skills.
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.
One benefit is that it can enhance the understanding of the original Harry Potter story. When writers try to 'help' in their fanfictions, they might analyze and explain certain aspects of the wizarding world better. For example, they could clarify some of the more complex magic spells or the political structure within the Ministry of Magic.
Hermione would be a great help. Her vast knowledge of magic and books could provide the necessary information for building the planet, like the right spells and magical theories.
Dumbledore might also play a role. He has vast knowledge and experience. He could offer some wise advice or even provide a special magical item or spell that is crucial for the unicorn's healing.
