    Summary

    In order to summon a small version of your Soulmate you need few ingredients: Milk, a Love Bloom flower, a small fragment of your soul and a monster to perform the ritual.

    You wanted to feel less lonely in your apartment.

    You did not expect to find yourself with your hands so full.

    Summary

    In a world where soulmates exist, monsters and humans have one thing in common: the first time two soulmates touch, a mark randomly appears somewhere--anywhere-- on their bodies to represent their match.

    It still doesn't make relationships easier...but maybe it does make them a little more interesting!

    * A collection of Soulmate AU vignettes for the Sanses and Papyri of various multiverses -- Undertale, Underswap, Underfell, Swapfell, & Horrortale *

    Summary

    You are well aware of your role and what you have to do be the counterbalance to both the Creator and Destroyer of the multi-verse it’s a good thing that neither one are aware of your existence, it makes the job that much easier to do but does get lonely...and unfortunately you’re comfy boring life is about to be turned upside down because you just messed up big time by revealing who you are and that you exist to others....

    What are you going to do now?

    The story always has to keep going and always has to keep moving...better turn the page and find out...

    (This is going to be a Ink and Error centered but you know I can’t help but throw in a couple others in the mix to spice it up.)

      i've read chapter 5, now 6 is to be read

      reader seems to be a skeleton who's "job" involves a library with books containing the code of different universes and their characters

      so obviously having to archive many possibilities requires taking a break, a warm cup of milk at underlust

      murder trio attacks, dream squad swoop in to save the day and now they wish to know what's your deal whilst your scrambling to not get involved

      warned reapertale of their fate and returned blue to his team, u passed out from lacking journaling, nightmare is against dream team cuz he wants ur aa

    Summary

    There's two new skeletons in the house.

    Unfortunately not much of a surprise there, the machine kept malfunctioning and kept bringing in alternate versions of Sans and Papyruses into their universe. They were up to SIXTEEN SKELETONS, now eighteen with the two's newest arrival.

    Except... there was something off about the new skeletons. 'Visor' and 'Chine'.

    Sweet mercy above, these two brothers seemed to hate each other. They kept swearing at each other, calling each other names- Chine actually almost stabbed Visor! On purpose! What a toxic relationship! Even more so than Black and Mutt!

    Or is it? Underneath their hateful facade, they do care for each other. In another very weird but unhealthy way... That's it, everyone was going to try and help these two, as well find out more about what happened to them in the past, why they were what they were and maybe find a little love along the way.


    You and your brother never asked to become the alternate universe Sans and Papyrus you both created. But by fuck was it difficult to keep things together like this, now the AU Sans and Papyruses were trying to get close. Stars above have mercy on their SOULs.

    Summary

    Sans has put in the bone work.

    For fifteen years, he's raised Papyrus.

    Not even counting the time loop.

    And now some pretentious ancient bones want to have a say?

    Oh hell no.

    -

    Said "ancient bones" are mortified.

    How were they supposed to know the short depressed skeleton was barely two decades old?!

    Summary

    A great source of despair draws Nightmare to an abandoned AU. There he finds an unfinished Sans with no name, no companions, no purpose, no world, and a soul. Nightmare gives him the option to get out of his abandoned, empty world. He accepts the offer but refuses to destroy anything or hurt people. Instead he finds another purpose. In return the Bad Sanses give him a home, companions, a life, and a name. They call him Ink.

    Or: Before he can destroy his soul and enter the Doodle Sphere, Ink is recruited by Nightmare. He accepts his role as best he can, even if he sometimes feels like he is meant for something more.
