    Summary

    (UPDATES EVERY FRIDAY. Maybe)

    NIGHTMARE is a sadistic bastard, that's just a fact. His goal is to corrupt Dream's soul and prevent the Doodlesphere from feeling positive emotions ever again. He has a new plan to do it. His brother is smart enough to know his games, but one of his friends isn't.

    INK doesn't know what to think of the letter on his nightstand. It only added onto the strange missing things and nightmares he's been having. Was Nightmare asking him on a date? Pfft, that was ridiculous, there was no way- wait. When did he get so pretty? When did Nightmare get so perfect?

    DREAM has the hope of the entire multiverse in his hands. With their best friend and Protector of the Doodlesphere missing, they have to do both Ink's job and their own, along with making sure no one else goes missing. He's stressed and exhausted, but he can't rest now. Come on Dream, stay . . . awake . . .

    Summary

    new summary:
    A long time ago, a skeleton with black tattoos found themselves alone in a white void, in one story, that skeleton went and became beloved by the multiverse that he protected, but in another, in this multiverse, that skeleton never took that journey, and stayed hidden, avoiding attention, the multiverse remaining unaware of their existence for years and years and years...

    until someone, dream, noticed.

     

    (old summery:
    I always liked the image of ink being a homeless hobo skeleton creature with no sense of shame or social norms, having no idea how to math because they have no actually education and basically clinical insane, I also like to imagine that by following his rule of "don't interfere with the goings on of the multiverse" he would act feral as fuck, So this is exactly what this is, dream and blue basically trying to tame the multiverse guardian ink. but like way more plot based)

    Summary

    After enduring centuries of constant wars and chaos across the multiverse, the gods stepped in to address the exhaustion felt by everyone. Tired of the ongoing pain and battles, a treaty was proposed by the guardian of positivity to prevent the multiverse from falling apart.

    The deal outlined a halt to creation and destruction, urging a balanced use of positivity and negativity without exploiting their power. Gods and immortals were forbidden from entering universes unaware of their existence to prevent unintended harm.

    Unaware that the creators were listening, the guardians and gods had to accept these rules permanently. Now, tasked by the creators, the guardians must guide and reform the protector and destroyer of the universes to protect their existence from a permanent looming threat.

    Summary

    The Council has been at war with the Emperor (more colloquially known as the King of Nightmares) for a long, long time. After defeat after defeat, they find themselves with no option but to request help from his fabled twin.

    However, Dream will not help them for free; he locks eyes with Cross, and decides he wants him in exchange for the war victory. It is an easy choice to make.

    But Cross is terribly apprehensive, because he his loyalty is not to the Council, but to Nightmare as his spy. He suspects Dream, Nightmare's mortal enemy, chose him knowing this, wanting information about his twin. And Nightmare is absolutely unforgiving of traitors.

    But he cannot offend Dream, for he too is an Immortal. He cannot forget that both Dream and Nightmare is dangerous, that any wrong move will end in his demise or worse.

    (He forgets, however, that he himself is mortal.)

    [OR: A Empire/Kingdoms UTMV AU, where Cross is caught between the crossfire of Immortal/Gods! Dreamtale Twins. Who are also influenced by God!Ink and God!Error; it's a cycle, really.]

    Summary

    In the beginning, there was a collective of voices. The collective needed a muse, for they could not create full universes. The only things they could make were unwhole sketches, and from one of those sketches, came their much needed muse, who was named Ink.
    At first, Ink obeyed their needs. Created what they wanted him to. But when Ink wants to create on his own, the collective, "The Creators", needed another being, as their viewing of Ink's creations were deemed useless for their multiverse.
    That other being is a glitch that fell into the anti-void, Error.
    But, even though this issue is easy to fix, stubbornness leads to otherwise.

    Summary

    Dream stared at the endless white and shuddered against how oppressive this place was.

    His eye lights focused on the only thing here.

    There was a skeleton on the ground with his hands over where his ears would be. Most of the skeleton had turned dark with glitches and the occasional error but part of his face and some of his left arm and torso was still white. He wore the typical Sans hoodie but with different colours and red glasses.

    He was muttering to himself.

    "Are you okay?"

    A.k.a: What if Dream had met Error before he completely went crazy?

    (This fic is inspired by For the Forgotten Ones.)

    Summary

    "Error, what did you do?"

    Ink didn't expect there to be AUs beyond the Doodle Sphere. Core Frisk never would have thought that there are things they can never see. Error never thought he would get his ass kicked by a bunch of humans.

    The Spider Society should probably have planned first contact a bit more.

    Ink went too far and Error is gravely injured. Error wants to live, and Ink thinks that he cannot exist without an antagonist. So they agree to fuse until Error recovers.

Young survivors flock to his care while their guardians can assist Core!Frisk in bettering the timeline, and he's even made some friends. And nobody knows that half of him is the destroyer of the multiverse! Everything is perfect.

    One day, Paperjam opens the daycare door to find a shorter version of a familiar face, a face that causes the minds behind his existence to destabilize. Will he be able to hold himself together? His existence, and Error's life, depends on it.

    Summary

    My interpretation and version of the Undertale AU Multiverse.

    What if each character has a purpose, like a game mechanic? What if they realize the choices they have are just an illusion for our entertainment? Will they try to change the narrative or accept their fate?

    English is not my first language, please excuse the mistakes. I hope you enjoy!
