Dumbledore's spirit might play an important role. Since he was so closely associated with the Hallows in the original series, his presence could offer guidance to Harry. He could appear in Harry's dreams or as a spectral figure, warning him about the dangers of misusing the power he has absorbed. And Voldemort's followers might also be significant as they could be after Harry to take the power of the Hallows for themselves.
Hermione would probably still be a main character. She'd be by Harry's side, trying to help him understand and control the power of the Hallows. She might be researching ancient texts to find out more about any potential side - effects or proper uses of the absorbed Hallows.
In addition to Harry, Hermione, and Ron, there could be other characters in this fanfiction. Dumbledore might play a role, even if it's just through his past knowledge or guidance that he left behind. Voldemort could also be a part of the story in some way. Maybe his spirit or his past actions are still influencing the wizarding world and Harry's need to unite the hallows is related to finally putting an end to Voldemort's dark legacy completely.
Hermione Granger might also be a main character. In the original series, she is an important part of Harry's journey, and in this fanfiction, she could be involved in new storylines, like solving some sort of mystery related to the 'Slutty Hallows' concept.
One interesting plotline could be how Harry's character develops in a different way after absorbing the Hallows. Maybe he becomes more powerful than in the original series and uses this power to reshape the wizarding world. For example, he could use the combined power of the Hallows to end the discrimination between pure - bloods and half - bloods once and for all.
Hermione could be there. She would be eager to study the different magics and books in Tamriel. Her intelligence would help Harry navigate the new world.
Hermione could be a main character. As a very intelligent witch, she might assist Harry in his teaching, like helping him prepare complex lessons or providing additional knowledge to the students. For example, when Harry is teaching about ancient spells, Hermione could offer insights from the books she has read.
Hermione could be one. She could come to Degrassi to help Harry. She'd be really good at handling the academic side of things there, like helping students with their studies. And also, she could use her magic knowledge to figure out any magical mysteries.
Hermione Granger would likely be a main character. She could use her vast knowledge to help Harry in his efforts to fix Hogwarts, whether it's researching ancient spells for repairs or coming up with new educational strategies.
Obviously, Harry Potter is one of the main characters as the title implies he is the one who keeps the Deathly Hallows. Hermione Granger and Ron Weasley are likely to be important as well, as they are Harry's closest friends and would probably be involved in whatever adventures or challenges come with Harry having the Hallows.
Dumbledore might play an important role as well. He would be guiding Harry through this new and strange situation. He could have some secrets about the Lord of Azkaban that he reveals to Harry over time. Also, some of the Azkaban guards or prisoners could become significant characters as Harry tries to reshape Azkaban.
Hermione would likely be one of the main characters. She would be curious about Harry's new heritage and might help him research more about Nyx. Ron could also be important. He might have some initial doubts or even jealousy about Harry's newfound powers, but in the end, he would stand by Harry. Dumbledore would definitely be a key character as well. He would try to guide Harry in understanding and using his connection to Nyx in a positive way.
