One interesting plotline could be that a new character discovers the Resurrection Stone and uses it to bring back a minor character from the series, like Colin Creevey. This creates a whole new dynamic as the wizarding world has to deal with someone who was brought back from the dead. Another plotline might involve the Stone being used to communicate with the founders of Hogwarts, seeking their wisdom to solve a modern - day problem in the wizarding world.
In some fanfiction, the Resurrection Stone might fall into the wrong hands, say a dark wizard who isn't as well - known as Voldemort. This wizard could use it to bring back a powerful army of the dead, which then leads to a race against time for the main characters to stop him. There could also be a plot where the Resurrection Stone has a side effect that no one expected, like slowly draining the life force of the person who uses it, creating a moral dilemma for the character who wants to bring back a loved one.
Maybe in the fanfic, the Resurrection Stone was never truly lost. It was secretly being protected by a group of centaurs in the Forbidden Forest. A young Hogwarts student stumbles upon this secret while exploring the forest. The centaurs test the student to see if they are worthy of handling the stone. If they pass, they are given the stone to use for a short time, but they must return it unharmed. This could lead to a series of adventures as the student tries to decide who to bring back, if anyone.
One interesting plotline could be Hermione discovers a hidden spell in the Sorcerer's Stone era that gives her the ability to communicate with magical creatures in a more profound way. This leads to her and Harry having adventures where they learn secrets from these creatures about the stone's true nature.
One interesting plotline could be how female Harry forms different friendships. For example, she might bond with Hermione in a more sisterly way, sharing secrets about being a girl in a wizarding world dominated by boys. Another could be her interactions with Snape. Since she's female, Snape might be a bit more protective or at least show a different kind of dynamic towards her.
One interesting plotline could be how Harry's character develops in a different way after absorbing the stone. Maybe he gains new magical abilities that are not in the original story, which could lead to unique adventures. For example, he might be able to communicate with magical creatures on a deeper level or have a stronger connection to the magic within Hogwarts itself.
Well, some might involve magical creatures with furry characteristics in new adventures at Hogwarts. For example, a werewolf character could have a unique story arc that intersects with the main Harry Potter plot. Maybe they are trying to find a cure or dealing with the prejudice within the wizarding world in a different way than what's in the original books.
One possible plotline could be a comical take on baby Harry's magical mishaps. Maybe he accidentally makes his diapers levitate or turns his crib into a mini Hogwarts. Another could be about how the other characters like Hagrid or Dumbledore interact with baby Harry in this unique situation, perhaps trying to figure out how to handle his early magical outbursts while he's still in diapers.
Perhaps a plotline where the ogre has some sort of special power that the wizards in Harry Potter are interested in. This could lead to a whole series of events where they try to either control or cooperate with the ogre.
In some fanfiction, a familiar might get lost in a different dimension. So, the main character has to go on a journey to find it. Along the way, they meet strange new creatures and learn new spells, which is really exciting. It also shows a different side of the bond between a wizard and their familiar.
There could also be a fanfiction where a member of the Sacred 28 discovers a long - lost family secret that has the potential to change the power dynamics among the pure - blood families. This secret could be related to a hidden magic or a forgotten alliance, and as they try to uncover more about it, they face opposition from other families who fear the change it might bring.
A common plotline is the characters' post - graduation plans. Some fanfictions might explore how Harry, Hermione, and Ron decide on their career paths. Maybe Harry is conflicted between becoming an Auror or a teacher at Hogwarts. Hermione could be considering further studies in ancient magic, and Ron might be thinking about joining his brothers in the joke shop business. This exploration of their future dreams and how they support each other during this transition period can be really engaging.
