Crossovers at Hogwarts (KH/FF/Others)

"Whether you come back by page or by big screen, Hogwarts will always welcome you home."
This story is a crossover between the beloved "Harry Potter" School of Witchcraft and Wizardry and the KH/FF world, with a few characters from other things as well. There's also a shitton of OC's chucked in there xD.
Anyway, this is a step out of my usual realm of 'reader insert' stories, but I'm looking forward to the change of pace, and the challenges that it will bring.
I hope you enjoy~!
