Since Smeltings is known for its strict and perhaps more traditional ways compared to Hogwarts' more inclusive and magical diversity. For example, a Smeltings student might struggle to adapt to the use of magic for everyday tasks at Hogwarts, like using a levitation charm instead of doing things manually as they were taught at Smeltings.
A possible plotline could be that a group of Smeltings students are sent to Hogwarts on an exchange program. At Hogwarts, they get involved in a mystery that's been plaguing the school, like the appearance of strange magical creatures in the Forbidden Forest. They use their different perspective and knowledge from Smeltings to help solve the mystery, while also learning about Hogwarts' secrets along the way.
There could be a character like Tom, a Smeltings student who is very disciplined but curious about the magical world of Hogwarts. He might be the main character who drives the story forward as he experiences all the new things at Hogwarts.
One possible plotline could be that Harry discovers a hidden magical world outside of Hogwarts. Maybe he stumbles upon a group of rogue wizards who teach him their own brand of magic, away from the traditional Hogwarts curriculum.

In this fanfiction, perhaps there are magical creatures that are drawn to the graveyard for some unknown reason. The students might try to befriend these creatures to understand why they are there.

One interesting plotline could be Harry discovering ancient magic secrets related to his status as heir. Maybe he finds a hidden chamber in Hogwarts that only the heir can access, filled with powerful spells and artifacts.
Well, perhaps a plotline where Harry has to deal with a new dark threat that is targeting Hogwarts specifically. As headmaster, he would use his knowledge of the Dark Arts and his friends' expertise to protect the school. He could also start new traditions at Hogwarts to boost the morale of students and staff alike.
One interesting plotline could be Draco trying to redeem himself in the wizarding world post - Hogwarts. He might start by using his family's wealth and influence for good, like funding charities for those affected by the war.

He could also be on a journey to discover a new type of magic that was previously unknown to him, perhaps something that can help heal the divides in the wizarding community.

For example, he might introduce some simple spells that could be useful for daily life in Camelot like a spell for lighting fires easily.
