Another theme is the idea of unfinished business. In many of these fanfictions, Harry as a ghost has something he still needs to do, like saving Hogwarts from a new threat or righting a wrong that he couldn't when he was alive. It gives a sense of purpose to his ghostly existence.
One common theme is the exploration of loss. When Harry becomes a ghost, his friends and the wizarding world at large have to deal with the loss of him in a physical sense. It's about how they come to terms with this new situation.
One common theme is the idea of the ghosts as protectors. In the seventh year, with so much chaos and danger, the ghosts could be seen as guardians of Hogwarts. Another theme is the connection between the past and the present. Since the ghosts are remnants of the past, they can bridge the gap for the current students.
One of the main themes is the clash of different realms. The Ghost King represents the realm of the dead or spirits, and when combined with the living world of Harry Potter, there are bound to be clashes. Also, the theme of redemption can be found in some. Maybe the Ghost King has some past misdeeds and is seeking redemption through his interactions with Harry and the others at Hogwarts. This can add a lot of depth to the story.
The theme of self - discovery is also popular. Jin's journey in the game is about finding his true self in the face of the chaos. Fanfictions can expand on this, showing his internal struggles more vividly and how he overcomes them to become the hero we know.
The theme of the afterlife often appears. Fanfiction ghost stories might explore different concepts of the afterlife, whether it's a peaceful place or a limbo where the ghosts are stuck. Also, the connection between the living and the dead is a big theme. It could be a psychic connection or just the fact that the living can sense the presence of the ghosts. This adds an element of the unknown and the spooky to the stories.
Love can also be a theme. Sometimes, there's a love interest who can either see or sense Bella in her ghostly form. This creates a very unique dynamic, like in some fanfictions where a new character falls in love with Bella despite her being a ghost. Additionally, the theme of redemption might be present. If Bella had some unresolved issues in her life before becoming a ghost, she might try to make up for them in her afterlife.
One common theme is identity. As a ghost, Percy often has to re - evaluate who he is. Another theme is isolation. Since he's a ghost, he may feel cut off from the living world. And then there's the theme of unfinished business. Usually, Percy has something he needs to do or resolve even in his ghostly form.
One common theme is mystery. The female ghost often has a past that needs to be uncovered. Another theme could be redemption. Maybe she was a bad person in life and is now seeking to make amends. And of course, there's often a connection to Hogwarts, like she was once a part of the school community.
One common theme is the idea of a spiritual connection. For example, in many fics, Harry Styles has a deep, almost otherworldly connection with the ghost. It could be a connection based on unfinished business or a past life bond.
One common theme is power exploration. Since the bloodlimit is related to ghosts, it often involves exploring unique and spooky powers. For example, the ability to phase through objects like a ghost or use spectral attacks.
One common theme is friendship. They are comrades in the game, so many fanfictions explore their deepening friendship, like how they support each other during tough missions.
