It's a lot more complicated than my title seems... I've been trying to find a word that describes this specific situation.
For example, there is the story "The Wizard of Oz" and then there's the re-telling of that story, "Wicked". Where the audience sees the point of view flipped, and now everyone who seem good is now bad and vice-versa. Would it just be a re-telling? Because I'm specifically looking for a word ( that's not really Conspiracy, because where I'd like to use it the "Conspiracy" wouldn't be one because it was true and confirmed within the story) that deal with situation that there was the "REAL STORY" under the first one presented.
"Wicked" isn't the official prequel to "The Wizard of Oz" but it needed that story to create this fan made " This-Is-The-Real-Story-Going-On-Here " one ( or " This-Is-What-Really-Happened" story ). What is that called?
I've basically come up with jack squat to figure out if there is a word or a small phrase to describe this, the closest word I've found ( besides Conspiracy, but that gives off the wrong connotation and overall vibe ) is Arcane. And ... That kinda barely fits the way I understand it. Is it really just called a "Re-Telling" and that's just it?
I'd just like to point out that "subplot" is also not the word I'm looking for
