So we all know of the Multiverses that Somewhat Switch up Roles of the Multiversal Sanses (or in some cases, Papyrus's now) or some like Dreamswap where it's Dream who eats the Apples instead, But what if there was an Au where Instead Ink and Error take Dream and Nightmares place and Ditto?
Well look no further than ShiftVerse!
ShiftVerse is pretty much an Au where the roles of the Sanses and AUs roles are Mixed up much like Story shift (which is actually sorta the inspiration of ShiftVerse) Ink is Dream, Dream is Ink, Error is Nightmare, and Nightmare is Error.
In place of Dream and Nightmares story, For Ink and Error, they are two Guardians (Error actually Formally known as Knitt's here), Ink Being a Guardian of the papers of Creation which could Create anything at the Whim of your pencil but couldn't Be controlled outside the Page and often Grew out of Control
And Knitt's the Guardian of The threads of Destruction, a Special Thread that Could Destroy anything It touched with the Whim of the Holder, Only downside is that it too should Destroy the Holder from inside out Till they Perished from the sheer power.
Ink was seen as the 'Golden' Child between him and Knitt's as ink protected something of pure "Good", while Knitt's was Despised and looked down upon for Protecting something of Such "Evil", Much like Dream and Nightmare's storyKnitt's was Bullied and Harmed for the unwanted but needed role of Destruction and that Knitts could degrade something's Durability but couldn't quite Destroy it unless it was already low
Ink was Used as a Tool for the small fact that he could Repair things (but not Create)
Anyways, it goes on With Ink being Completely Clueless and Ignorant to Knitt's suffering till he Reaches his Breaking point where maybe if He's able to Hold one of the Pure Papers of Creation, he'll be seen as Equal to Ink, but due to Knitt's being of pretty much Pure Destruction, It ended up Tearing the Page into a Thread (Fabric paper? Yeah why not), aka a Thread of Destruction, to which It started Corrupting the other Pages (as of now idk if it'd also be a Tree or not but for story purposes why not) so in the Panic, Knitt's Tries to absorb the Threads in Hopes that it would Stop the other threads from being Corrupted, yada yada I think we kinda all know how Dream and Nightmares Story go, but in this one the Threads form in ways as Tear marks and a Blood like looking Line from his Mouth too, Ink meanwhile, Noticed the Commotion going on around the Tree and went to go check it out, Saw what was Happening, Tried to Stop the Villagers From Hurting and getting to Knitt's, kinda ends up Failing at that, at that point the Tree has been taken down and Knitt's has pretty much Absorbed most of the Threads, he ends up Killing the Villagers while Ink is Trying to Process wtf just happened, Ink Finnaly comes to his senses and sees there's a Last paper so he Quickly Grabs it and too kinda Absorbs it, the two fight, yada yada-, Ink is Turned into A Statue and then Knitt's goes off to Cause Havock on the Multiverse for 500 years
Now in place for Ink and Error's story, Dream is the God of Positivity and Nightmare the God of Negativity. Dream, like ink, is Soulless but due to his Positive Nature and Magic he actually Hides the fact really well
Nightmare is an Insane Egotistic Manic who's Goal is to Eradicate the World of Emotions by Draining the Essence of worlds and therefore draining them of their Emotions, he also believes he's better than everyone while being a Mistake at the same time. Anyways, Dream Typically Prevents or Restores a World's Essence when Nightmare Goes to Consume or take a Worlds Essence, though Typically the Frisks of the worlds (or whatever character the Protagonist might be in an Au) will be Rendered Emotionless till Dream Retrieves it from Nightmare since Nightmare can't consume the Essence of a Determined soul as they are way to Potaint for him actually to consume so the essence usually is kept within Cacoons of Negativity within the Void (just because, the Anti void and Void Are Also Swapped in this au hehe).
As on mentioning the Void, Like Error sort of, Nightmare had gone insane due to the Sheer Darkness of the Void and Corrupting Effects it had when someone Stayed within too long, for Nightmare that meant Goop-ifying him (and his goop is a dark Purple with Lighter Purple Accents)
So yeah Dream and Nightmare are Within this Internal war for a Long time till Ink is Freed from stone and Found by Dream to where they start the Nebula Sanses, Knitt's on the other hand started a Gang with Outer (Staring as Kills✨), lust (Staring as Dust), Fell (as Horror), and at some point Swap (who stars as Cross)
At some point Ink and Dream also recruit Cross at some point (who stars as Swap✨)
