    Summary

    In a Multiverse where Ink and Error retire together after falling in love. Dream is now the new leader of the Star Sans and protector of the multiverse.

    With Error no longer a threat, Dream focuses his effort in pacifying the other big threat to the multiverse, his brother Nightmare. In an attempt to cure his brother of his curse of negativity, Dream uses a rather volatile serum from a rather lewd AU.

    How will this series of events play out? And how will the multiverse fair without Ink and Error?

    Summary

    Being dragged to a club with drunken goons all around wasn’t exactly your cup of tea, but if it meant making your best friend happy then you would suffer through the stench of alcohol and ear bursting music all night long.

    You had not prepared to end the night with a bleeding heart, though.

    Summary

    "You truly are an idiot!" The spirit hissed the words out like poison as he glared at the wounded skeleton who was clinging to the balcony at night. The skeleton called Cross, only sighted quietly and watched the cops go by on the ground.
    _______________________

    Cross knows that the city is a dangerous place, but he made the mistake of living there and found himself a job, a dangerous one that puts him at risk every time he does it.

    But what do you expect when you work for the crime king?

    Summary

    Four AU’s have come to a happy ending on the surface. It is a new beginning for everyone, but Berry is haunted by his past that still clings to him and threatens to pull him back into the darkness, unknown to his now growing skeleton family. The newest skeletons are from the last set that surfaced: Fellswap. They are not going to let Berry be taken. Howl and Daemon, the two newest skeletons, have to dig into a horrible truth and show the world Berry’s past, and with the help of their fellow skeletons, they hope to make a better future for him and all other monsters.

    This is adapted from a role play with GetMcDunkedOn and me (Diyami). I hope you enjoy it.

    Summary

    "Don't be surprised if this doesn't end the way you want it to."

    "Oh do not worry, it will. This is what brought them here, and if it wants them back, who am I to stop it?"

    He only worries for their safety, but who is he to judge the other's decision?

    A malfunction of this magnitude is improbable, but not impossible:
    That was when they saw it, two beings, one larger and one smaller. While the machine had once spat out skeletons on a regular basis, it was deemed derelict after the last two came through over 6 months ago. It seemed other universes lacked the means or the will to travel elsewhere, thus it was shut off for good; the safety of the skeletons and the city was considered more important than the possibility that untamable beings traveled through. How could it have produced two more if it was unplugged? And why had it exploded in the first place, it was unpowered! All of their minds filled with fear, curiosity, and gloom.

    Summary

    They suddenly get teleported into the game though, with Kris as their sibling and them being a target for manslaughter via rotting corpses.

    Summary

    (In This Twisted World, Where Villains Rule)

    Lust Sans ("He's a Sans, why's he like that") was so, so tired. He gets that his world and denizens are unsavory compared to many other Universes, but other 'Sanses' took one look at him and dismissed them all. All their pain, their grief, their loss and sadness.

    Is being loved genuinely so much to ask?

    As if the God of Creators (that's Toby) heard his wishes and decided to pity the broken Monster.

    And here he is. In the world of Villains. How ironic. But at least, he wasn't looked at with scorn and disgust.

    Summary

    [Y/N] [L/N] is a powerful mage with a bloodline well-known throughout the ages and her family have always been celebrated. They, however, despise how their bloodline trapped monsters beneath the ground. But, that is for another day. In not being able to afford basic accommodation for university, they had to rely on an old (and terrible) friend named Bethany. For some reason, most of Bethany's skeleton mates despise [Y/N] but why is that? Apart from the fact she is a mage?
    Just because she has a kindness soul, it doesn't mean she will stand for their bullshit.

    Summary

    Skeletons are stuck in a survival game with a reinvented caveman MC.
    Some know the MC as their favorite character, and some know them as the savage able to sniff them and tell their part in society.
    Too bad it doesn't go like that, and MC has more to be uncovered.
    Literally most of this is inspired by those alpha/beta stories

    Summary

    Where was I? The last thing I remember was defending my home from invaders with my family. Now I was stiff and cold. It was hard to breathe. I pushed and shoved, there was a ripping and a tearing, suddenly I was blinded by the sheer light that was forced onto my eye sockets ...

    --
    this is about ATE Dust in the Winged multiverse
    This story won't be rated G entirely, It's just the first part. I will change it accordingly to the released chapters. Just a tip to you all, this story will have violence and it may disturb some audiences.

    If you haven't read ClicheAly's writing, you won't know how gruesome some parts are and you won't know anything about this Dust or his AU, so I highly suggest that you read Murder to Dust and An Alternate Turn of Events before you read mine.

    It is also good to know that this is taking place in the Winged multiverse, soo I also highly suggest you read WrittenKinzy18 stories and series.

    Summary

    Gyftmas fic for @Mysteryficanon!

    It's a complex polycule: Comic is dating Red, Blue, and Black. Red and Blue are each (separately) dating Plum, and Blue is dating Black outside of Comic too. They all make it work, though. No jealousy, no favoritism. Just sweet sweet romance and a variety of different kinds of dates.

    Comic, Blue, and Black all go wining and painting together; Blue and Plum go rock climbing; Comic and Red attend their weekly trivia night; Red and Plum exchange Gyftmas gifts and go to a sex party.

    Summary

    Ink had never really been interested in dating or being intimate with anyone before. He didn't know much about either at all, on top of it. But if these collections of creators' fanfics he'd been reading lately meant anything, it meant that he could keep that promise: he could make his own story, just like that creator had wanted. It would take some studying and a supporting cast, but he could probably gather something. Something that wouldn't disrupt the AU's already-existing storylines... and yet be something he could call his own.
