One plotline could be that a young wizard finds the ashes of a phoenix and they start to have strange dreams. The dreams lead him to discover an ancient magic that was thought to be lost. Another could be that a group of Death Eaters try to steal the ashes to use in a ritual to bring back Voldemort in a more powerful form.
Well, in some 'Ashes of the Phoenix' fanfictions, the plot could revolve around a prophecy related to the ashes. A character is fated to use the ashes to prevent a great disaster from befalling the wizarding world. Or perhaps the ashes are used to resurrect a beloved character who had died. There could also be a plot where the ashes are being hunted by different factions, each with their own motives for wanting to possess them, and the main character has to protect the ashes at all costs.
One possible plotline could be that Harry Potter decides to take on the Dark Arts in a more proactive way. Instead of just reacting to Voldemort's attacks, he studies the Dark Arts himself to find weaknesses, which is a very bold move for him considering the taboo nature of the Dark Arts in the wizarding world.
Well, 'Ashes of the Phoenix' in Harry Potter fanfiction could be a really creative take on the lore of the series. It might be about a post - battle scenario where the phoenix has sacrificed itself and its ashes hold some sort of key to restoring something, like a magical place that was damaged during the war. It could also be a story that focuses on a new character who is mysteriously linked to the phoenix ashes and their journey to understand this connection.
Sure. One example could be a plotline where Harry discovers he's actually an alien from another dimension and his magic comes from that origin rather than his wizarding heritage. Another could be a story where all the Hogwarts houses merge into one super - house and there are no more rivalries or differences between the students. And there might be a plot where the Marauder's Map actually turns into a living being that can guide Harry on adventures that have nothing to do with Hogwarts or the wizarding world as we know it.
One plotline could be that Hogwarts is under a new curse that makes the castle itself a dangerous place. The staircases are constantly shifting in a more erratic way, and there are hidden traps everywhere. The characters have to navigate this while also dealing with a new group of dark wizards who have infiltrated the school.
One plotline could be that Harry discovers a hidden diary of Kitiara's and it reveals secrets that set him on a quest to protect her legacy.
One example could be a fanfiction where the author cuts out all the Quidditch scenes from the original story and focuses on the academic and personal relationships at Hogwarts. This would give a different perspective on the characters' lives without the sport aspect.
One example could be 'The Dominant Potter' where Harry discovers a new and extremely powerful form of magic early on and uses it to take charge in the fight against Voldemort. He is shown as being dominant in strategic planning and combat situations.
A possible example of 'harry potter dissociate fanfiction' is a story where Voldemort's Horcruxes cause dissociation in the wizarding world. The presence of these dark artifacts could be making the magic itself split or act strangely. Wizards and witches might find themselves dissociating from their normal magical abilities or from the magical community as a whole as they try to deal with the chaos caused by the Horcruxes.
Some fanfictions that are overly long - winded and full of filler content can be considered the worst. They might have pages and pages of a character just thinking about nothing important or going through mundane daily activities that have no real connection to the main plot of the Harry Potter world.
One example could be a fanfic where Harry has the ability to control time without any limits, which is much more powerful than the time - turning devices in the original series. Another might be a story where Voldemort is made invincible and can defeat any opponent with a single spell, completely overpowering the other characters.
