You could have an OC that is a transfer student from a different town where strange things have also been happening. This OC could have some knowledge about the otherworldly events that the kids in Hawkins haven't encountered yet.

One idea could be exploring a different timeline where one of the main characters made a different choice at a crucial moment.

This might give the wand wielder an edge in combat magic. There could also be fanfictions that deal with the malfunction or corruption of a magical core, leading to unforeseen and dangerous magic. Some might even create new types of magical cores based on mythical beasts not mentioned in the original series, like a basilisk fang core which could have venom - related magic abilities.
