Ah, soudesune...

A fan-fic is a fiction totally made up by fan(s) with almost no relation to the canon storyline though it borrow elements from the story, I think your story here is a fan-fic

A fan-on is a (though) fiction made up by fan(s) but is somewhat connected to the canon storyline, e.g. you tell a story about Sabo post explosion.
