    Summary

    Cross finds himself responsible for the death of his universe. After years in the white unending void, his tears summon Nightmare, who brings him back to the Castle.

    It’s the aftermath of a more brutal XTale au, where Cross deals with PTSD and OCD, while trying to make a place for himself in the gang. It’s difficult, when you make mistakes left and right.

    Summary

    There were many things that kept the multiverse running; systems that worked side by side to make sure everything didn't fall apart in an instant. The most well known of these systems were the three main balances.

    Life and Death, Creation and Destruction, Positivity and Negativity — all completely necessary aspects to the universes and the people within them.

    Four Gods and two Guardians maintain this balance, but the multiverse has strange ways of protecting itself as well.
    ~~
    A One-Shot booklet of the Dragon Balance AU, with some additional pictures. I can't promise regular updates or lengthy chapters every time, but I'll do my best.

    Summary

    Running from your past isn't so simple when it's actively trying to catch up with you. Cross never had a simple life, no luxury, rare instances of happiness. When he finally breaks free, he's willing to do whatever it takes to stay out of the chains of a puppeteer.

    An Underverse fic where Cross is in hiding from XGaster and gets taken into Nightmare's gang.
    (The tags make it seem more horny than it is, it is horny in places but it's a more serious fic about morality and difficult emotions.)

    NOTE: Cross is not sharing a body with Chara in this fic.

    Summary

    After Geno messed with his DETERMINATION he ended up in the Anti-Void. Slowly, he became insane, as he started to become a Error. Somehow, he finds a way out. Though, the AU he ends up in is unfinished and drained of hope, everyone is unfinished, except one little skeleton.

    Or

    Geno finds a way out the Anti-Void before he fully becomes Error. He ends up in ____Tale, and finds Ink. Ink is still a child and undeveloped, years away from ripping his soul. Geno and Ink find themselves in another AU, exploring and trying to live. While the rest of the Multiverse falls into chaos.

    (Inspired by Prism's Tale in FTFO as well as FTFO itself)

    Summary

    Your life was terrible. Terrible working conditions. Terrible fiancé. Terrible relationship with any and all people around you. The only good thing that happened to you was getting struck by lightening and waking up in a house full of skeletons.

    Okay. Maybe not quite a good thing to happen now that you think about it.

    Summary

    Dream had gotten used to being called “a gift.” He was a gift to the Villagers, he was someone they could rely on.

    It wasn’t long until Dream realized that “gift” also meant “object.” It meant “possession.”

    Even though it had been years since the destruction of Dreamtale, the Guardian still believes that he is just a possession for the people of the Multiverse.

    There is no way Cross will let Dream continue to believe that.

    Summary

    There wasn't a creature in the entire multiverse quite like Nightmare. Most viewed him as an insane overlord high on power, but he radiated far too much calculation and control for blind madness to be the cause of his personality. No, he was smart. Incredibly so. He best be, as he ran an entire kingdom of misery and suffering just out of reach from the universe's nosey "Saviors."

    Cross had a difficult time deciphering his master's intentions. One may argue that he had no choice in being the ravenous king he is now, but that life had forced him down the path long ago for the sake of feeding. That's what this is all for after all. The pain and suffering. It was to feed the king. Cross couldn't despise him for such a basic necessity, no matter how foreign the concept and how often hunger turned the king's attention his way.

    His servitude didn't go unrewarded. He had a fraction of the dark palace that he could call home. In a multiverse that had played him dirty, that one prize meant everything to him. He would just go ahead and label himself insane if he didn't put his entire soul into protecting this second chance, and by extension, Nightmare.

    HAPPY PRIDE MONTH!!!

    Summary

    The Council makes a deal with the fabled God Dream for his assistance in defeating his tyrant God twin, Nightmare. 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's an easy decision, is it not?

    There's just one problem with this arrangement: Cross is a spy, sent by Nightmare himself. And Nightmare is absolutely unforgiving of traitors. But he cannot offend Dream, for he too is an Immortal. He cannot forget how dangerous they both are, how any wrong move will end in his demise or worse.

    (Cross 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 have also been influenced by God!Ink and God!Error; it's a cycle, really.]

    Summary

    Ink is often thought of by the inhabitants of the AUs as a "god" but that is far from the truth. In reality, Ink is the Creation Mechanism, a tool created by Fate to serve the Creators in their creation of AUs. But Fate didn't realize what that would truly mean, especially in a multiverse with limited capacity. Fate warned Ink about this, but the Creators are heedless to it, so it really doesn't matter if Ink even remembers the warning.

    Frustrated and desperate to do something to prevent catastrophe, Fate creates Error, a Balancer who is actually under her control, to try and curb the issue, but it isn't clear whether that will be enough. And Error isn't as willing to go along with his new role as Ink is.

    Ink has always felt it wasn't his place to question the Creators or his role in the Multiverse, but when he meets Error, that begins to change.

    Meanwhile, Destiny watches in the background, as she always does, plotting a way to free them both from the chains of Balance. And the duo's friends don't intend to stand idly by either.

    Summary

    Its been at least 500 years since Nightmare trapped his brother in stone. At least, that's what he guesses. It makes sense that Dream hasn't aged a day under the stasis spell.

    --
    An AU in which when Dream gets out of stone, he is still a child. Nightmare is (mostly) sane, and has a family to call his own, but when Dream makes his way back into his life he can't help but try to give Dream the childhood the apple incident stole from them.
    *update*
    figured out how to gift and put down my inspiration so please go check out One Small Dream by Calcium_Cat if you haven't already since after reading their fic I realized I simply needed more baby Dream. Then my mind went haywire for Dream (the boy TM) and I started writing this :D

    Summary

    ‘If not Nightmare, who are our assets right now, and what are the skills they can offer?’

    Cross looked up, still trying his best to comfort a shaking skeleton in his arms.

    ‘Dust is out of commission. I won’t be able to calm him down enough in time. He is freaking out and seeing as they got us into this situation, I bet Killer is having one hell of a laugh-’

     

    Killer wasn’t moving.

     

    Looking over his shoulder, Cross expected to find Killer enjoying the thrill and probably doing something stupid, digging them deeper into the ground.

     

    Why wasn’t Killer moving?

     

    They just sat there, staring. Their crooked smile plastered uncomfortably. Their void eyes empty and hollow.

    It was… Concerning. Calculating. Cold.

    Summary

    Cross didn’t know what came to him.

    Maybe it was a guard instinct, maybe it was his fight or flight mindset. But, at the moment, he really, really, wanted to punch himself for not just daring to think this was a good plan, for not just having the impulse, almost automatic instinct of saving someone, but that someone being Killer.

    His ideas were not always the brightest.
