Winky could also play a significant role. Maybe she has some special knowledge about the dark magic that is endangering Harry. Despite her past troubles, she could rise to the occasion and use her skills to contribute to saving Harry.
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.
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.
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 is often very popular in fanfiction. Since he was already a rather unique and brave house - elf in the original series, in fanfiction he can be portrayed in even more heroic or complex ways, like leading a revolution among house - elves.
Dobby is definitely one of the most popular. His character from the original books was so endearing and his actions so brave that he often features prominently in fanfiction.

Winky. She is a meek house - elf who was in the service of the Crouch family. Her story reveals a lot about the house - elf society's strict rules and how difficult it can be for them to break free from their masters' control.
Dobby is often a very popular character in house - elves fanfic. His rebellious nature and his loyalty to Harry Potter make him an interesting subject for further stories. Writers can explore his life before and after his freedom.
There is also Kreacher. He serves the Black family and later has an important role at Hogwarts. He has a rather surly and complex personality. He is very loyal to the Black family, but also has to adapt to new situations after Sirius's death. His actions are often influenced by his long - held family traditions and grudges.
Perhaps some of the pure - blood wizard families who look down on house elves training a wizard like Harry could be antagonists. They might see it as a threat to the traditional wizarding hierarchy and try to stop Harry and the house elves, thinking that it's not proper for a wizard of Harry's status to be trained by 'mere' house elves.
Another way they could use their magic is by communicating with other magical beings. They could send out magical signals to the friendly creatures in the area, like the owls or the garden gnomes. The owls could then fly around and create a distraction, while the gnomes could help the elves dig secret tunnels for Harry's escape. The house - elves' magic is not as well - known as wizard magic, but it is very powerful in its own way and can be used creatively for the rescue.
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.
