In this fanfiction, it could be that the house elves are aware of a prophecy that involves Harry's death. They take it upon themselves to protect him. They might start by disguising Harry's presence in Hogwarts. When the danger approaches, they use their ability to apparate within the school grounds (even in areas where normal wizards can't) to whisk Harry away to a secret location that only they know of, thus saving him from his would - be attackers.
Perhaps Voldemort has cast a powerful spell on Harry that the normal wizarding community can't break. But the house elves, with their different kind of magic, are not affected in the same way. They detect Harry's plight and use their loyalty and cleverness. For example, they might create a magical shield around Harry that slowly weakens the dark spell, eventually saving him.
Dobby would likely be one of the important house elves. He has shown great courage and a willingness to go against the norm to help Harry in the original series. In this fanfiction, he could be the leader among the house elves in the rescue mission.
Maybe the house elves train Harry in the art of stealth. Since they are so good at moving around unnoticed in the wizarding world. They could pass on those skills to Harry, which would help him greatly in his battles against Voldemort and his Death Eaters. Harry could then use this new - found stealth to gather intelligence or surprise his enemies.
Well, it could be about Harry Potter being invited to the council of elves. Maybe they need his help to deal with a dark magic threat that is affecting the elven realm. Harry's unique skills and knowledge from Hogwarts could be put to good use in this elven adventure.
Dobby is often very popular in fanfiction. Since he was already a well - developed character in the original series, fanfiction writers like to expand on his story further. He might be shown having more adventures or getting into different kinds of trouble. Another popular one is Kreacher. Writers may explore his complex personality more deeply, perhaps showing a side of him that was not fully explored in the books, like his loyalty to the Black family in new and interesting ways.
Well, it might be that Harry Potter is accidentally transported to a non - magical realm where he is in trouble because he doesn't understand the Muggle world completely. The Queen, who has some knowledge of magic or is in contact with a secret magical society, discovers Harry and saves him from the perils of this strange new world for him.
One possibility could be that Voldemort has a sudden change of heart. Maybe he realizes that Harry is the only one who can truly understand his loneliness and power. So instead of killing Harry, he decides to save him from a dangerous situation, like a powerful dark magic that even Voldemort fears could destroy the wizarding world if not controlled, and in the process, they form an unlikely alliance.
In the 'Harry Potter Saved by Demons' fanfiction, perhaps the demons are not as evil as they seem in the traditional sense. They might be outcasts from their own demon realm. When they come across Harry, they recognize his power and the danger he's in. They decide to save him because they believe that by doing so, they can change the fate of both the wizarding world and their own world. So they use their unique demon abilities to keep Harry safe from harm.
Well, perhaps the Winchesters, who are known for hunting supernatural beings in their own universe, find a way into the Harry Potter world. Maybe they sense some dark magic that the wizards in Harry Potter's world can't handle on their own. They then use their skills and knowledge of the supernatural to save Harry from a powerful dark wizard or a dangerous magical creature.
Well, it could be that Hera, perhaps using her divine powers, steps in when Harry is in a really tough situation in the wizarding world. Maybe she saves him from a powerful dark spell or a dangerous creature. For example, when he's facing Voldemort, Hera could use her magic to shield Harry and give him the strength to fight back.
One possibility is that Harry grows up learning the elven ways. He might become an exceptional magic user among the high elves, mastering their unique spells and skills. For example, he could learn their advanced archery combined with magic. His connection to the wizarding world might also bring new elements to the elven society, like introducing some wizarding inventions.
