You could write a fanfiction where the characters from House of Anubis participate in an international competition of some sort, like an ancient Egyptian knowledge quiz or a magical skills competition. But they soon realize that there's a hidden agenda behind the competition that ties back to the secrets of the house. This would bring in elements of rivalry, teamwork and mystery all at once.
A fanfiction could focus on a new student arriving at the House of Anubis who has a special power related to the ancient Egyptian magic in the house. For example, they can communicate with the spirits that are often associated with the mysteries there. This would change the dynamics as the other students have to figure out if this new student is a help or a hindrance.
One idea could be to explore a new mystery in the House of Anubis. Maybe a hidden chamber is discovered that has ancient artifacts and secrets related to Anubis. Another could be to have a character develop a new power or ability that is connected to the Anubis mythology. For example, they can communicate with spirits in the house that hold important information about the past.
One idea could be a time - travel fanfiction where Fabian and Nina go back in time to the era when the House of Anubis was first built. They could discover secrets about the house that were long forgotten.
One idea could be that Eddie's OC is a long - lost relative who comes to the House of Anubis with a mysterious mission. Maybe they are searching for a hidden artifact that has a connection to the Anubis legend. This could lead to all sorts of adventures and interactions with the other characters, especially Eddie.
One interesting Peddie fanfiction could be where they go on a mystery - solving adventure outside of the House of Anubis. Maybe they discover a long - lost artifact that has a connection to their own relationship.
One interesting plot idea could be a crossover where Percy and the Son of Anubis have to team up to stop a common enemy that is threatening both the Greek and Egyptian mythological worlds. For example, a powerful demon that is using the chaos between the two worlds to gain strength.
One idea could be an OC who is a brilliant but unorthodox medical student. They constantly clash with House in their diagnostic methods yet prove to be surprisingly accurate at times. For example, they might use a new technology or approach that House is initially skeptical about but later comes to respect.
Well, you could write a fanfiction where the House of Black has to face an external threat. Maybe a dark wizard from another family is trying to steal their secrets or undermine their power. The fanfiction could focus on how the members of the House of Black strategize and use their unique skills to defend themselves. Or perhaps a story about a forbidden love within the House of Black, where two members from different branches of the family fall in love, and they have to deal with the strict family rules and traditions that oppose their relationship. Also, a plot could be about a young member of the House of Black who discovers a new form of magic that has been lost in the family for centuries and how they bring it back to glory.
In some fanfiction, there might be a plot where Claire Underwood has a female rival within the political arena. This could lead to intense power struggles between the two women, with Claire having to use all her wits and charm to outmaneuver her opponent. There could be a lot of political intrigue, back - stabbing, and strategic moves.
One idea could be to explore the backstories of the wax figures more in - depth. Maybe there was a particular event in their past lives that led them to be made into wax figures.
