What are some interesting plot ideas for a 'Harry Potter in Slytherin House fanfic'?

One idea could be a story about a house - elf who discovers a hidden magic within themselves that allows them to break free from the traditional bonds of servitude. They could then go on a journey to find other house - elves and teach them this new magic.

There are various plot ideas. Some fanfictions might explore the idea that the heir of Slytherin is not a single individual but a group of people who have been secretly working to change the reputation of Slytherin house. They could be working against dark wizards within the house who are trying to revive the old ways of pure - blood elitism. Or perhaps the heir has a connection to an ancient magic that is tied to Hogwarts itself, and in order to save the school from a new danger, they must unlock this magic. It could also be a story where the heir is in a love triangle with a Gryffindor and a Hufflepuff, adding a romantic element to the plot while still dealing with the challenges of being the heir of Slytherin.
