One interesting plotline could be a detailed exploration of the post - battle recovery at Shell Cottage. Maybe characters dealing with the emotional trauma while staying there. For example, Hermione helping to heal Ron's more hidden wounds from the battle.
A third plotline could be centered around a love story that blossoms at Shell Cottage. Perhaps a minor character falls in love with someone unexpected, like a local wizard who helps them during their stay. Their relationship could face challenges due to the post - war chaos and differences in their magical upbringings.
Another plotline might involve the discovery of hidden magic within Shell Cottage. It could be that there are ancient spells inscribed on the walls that only become visible in certain moonlight phases, and the characters have to figure out what they mean and how to use them. This could lead to new adventures and revelations about the wizarding world's past.
A plotline could involve the 'cucklord' having some sort of hidden agenda related to Shell Cottage's location or the magic it holds. They could be trying to use it for their own gain, like accessing a powerful magical artifact that is hidden there. They might manipulate the characters living in the cottage to achieve their goals, creating a lot of tension and drama as the other characters try to figure out what's going on.
One idea could be exploring the daily lives of the characters who stay at Shell Cottage. For example, showing how they heal and recover from their battles. Another could be a story about the hidden secrets of Shell Cottage that are slowly uncovered by the characters. Maybe there are magic spells or artifacts hidden there.
One possible fanfiction could be about a character finding a magical lemon tree near Shell Cottage that has special healing properties. The lemon's essence is used to cure a minor ailment of one of the main characters.
Obviously, Harry, Hermione, and Ron are often main characters. They are the central trio in the original series, and Shell Cottage is an important place for them in the later part of the story. So fanfictions usually continue their journey and character development there.
It could be a really strange or creative take on the events around Shell Cottage. Maybe it involves some sort of power play or unexpected character interactions that the author has labeled with this rather odd term 'cucklord'. However, without reading the actual fanfiction, it's hard to be more specific.
Obviously, Bill and Fleur could be main characters since Shell Cottage is their home. They could be dealing with the post - war situation, like how to protect their home and family from any remaining threats.
One interesting plotline could be about the Founders' initial meetings and how they decided to build Hogwarts. Maybe they had different ideas at first but then came to a consensus on the school's values and layout.
Well, perhaps in this fanfiction, the Phoenix plays a role in revealing hidden secrets about Harry's family. It could lead Harry to discover an ancient magic that was long forgotten by the wizarding world, which was somehow related to his family. This could then set him on a new quest, different from the one in the original books, and change the course of the story completely.
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.
A possible plotline could be a time - travel fanfiction where Harry and his friends accidentally travel back in time to the era when the founders of Hogwarts were alive. They get to interact with the founders, learn about the early days of Hogwarts, and face challenges that come with changing the past or ensuring that history unfolds as it should. This would involve dealing with the different magical cultures and practices of that time, as well as the complex personalities of the founders.
