Who could help Harry Potter when he finds a sword in a fanfiction?

One possible plot could be that Harry stumbles upon the Sword of Gryffindor in a hidden chamber in the Forbidden Forest. Maybe he's on a solo quest to find a powerful weapon against Voldemort and the magic of the forest guides him to it. Then he has to figure out how to use its power to his advantage in the upcoming battles.

His best friends Hermione and Ron would surely be there to help. Hermione with her vast knowledge of magic could research about the egg, and Ron with his loyalty would stand by Harry's side in any danger related to the egg.

Hermione would most likely help. She's always been there for Harry, and with her vast knowledge from books, she could offer a great deal of advice on how to take care of the dragon egg. Ron might also be involved. Despite his initial fear of things, he has a brave heart and would probably stand by Harry's side.

One possible plot development could be that Harry first goes into denial. He has grown up thinking his situation was normal. But as he realizes he's been abused, he might start to distance himself from those who have been part of the abuse, like the Dursleys. He could then seek out help from his friends at Hogwarts, like Hermione and Ron. They would support him, and together they might try to find a way to deal with the emotional and psychological trauma he has endured.

Hermione would surely be one of the first to help. She is highly knowledgeable in magic and would likely try to use a healing spell or find a potion to stop the bleeding.

The genie might be a transformed wizard. Some powerful dark magic could have turned a wizard into a genie as a form of punishment. When Harry finds the lamp, he unknowingly releases this wizard - genie. This genie - wizard could have knowledge of magic that has been long forgotten, which could be very useful for Harry in his fight against Voldemort.

The baby could be the child of a minor character from the original series who was in hiding. For example, the baby might be the offspring of a wizard who was on the run from Voldemort's followers and unfortunately didn't make it, leaving the baby behind for Harry to find.

Dumbledore, if he were still alive in the fanfiction, would likely have some wise words and advice for Harry. He might have some secret knowledge about dragon transformations that could be crucial in helping Harry. Also, Neville could come in handy as he has proven to be brave and resourceful, and he might be able to find some rare plants that could be of use to Harry in his new form.

It could be an evil dark wizard. This wizard might have created the mask with the intention of using it for some nefarious purposes, like taking over the wizarding world. But before he could use it, the mask was lost or hidden, and now Harry has found it.

It could be a dark wizard who wants to get his hands on the lightsaber for its power. He might see it as a new tool to use in his evil plans, like using it to break into Gringotts or to fight off any who oppose him.
