    Being reborn sucks. I'm now the oldest sibling of Sans Au ship children. I'm the Daughter of Dream, Error, Nightmare, and Ink. So I have a mix of all their powers. Great! Now my parents are all trying to get into my and my siblings' lives! Bruh!! They left us! I'll protect my siblings, not you four!! I've raised them mostly. Ink and Dream had Palette for a bit. I own nothing but my Oc and the story line.

    Once upon a star a wish was heard. "I wish I had a brother who would understand me, who would be on my side, who wouldn't betray me" But sadly the multiverse died. Too much positivity, too much creation, too much life... "It's not fair that they need to suffer just because of some incompetent Dities" A creator takes over the dead multiverse. "It's time to start from new" The multiverse resetted itself. "This time around no forced god, no blind judges and no Dities" But something happend... something unexpecting... The creator got pulled in that multiverse as Nightmares new brother. "My name is @%@#& Wishmaker I make Dreams come true" *chuckles* "I hope my dear creator wont be angry at me for this little 'accident'. Besides a litlle break wont hurt aren't I right?" "Bro... Why?"

    I died. I thought hey at least I got reincarnated and have a second change to be happy. Only then I noticed I couldn't leave and even worse I was alone. Heh, this has to be a joke... Fate can't be... Oh wait, she is. Hahaha... again and again and again and again and again... Once I am happy I just get taken everything away. Over and over again. Why should I even keep going? There is no reason... Why can't I just die? I would finally rest in peace. Oh wait I also need to stay dead or I just get reincarnated again... Wait I am Geno... and he is undead... Does that mean... I CAN'T DIE?! I hate my existenz... I may be Geno but I will choose my own name. Zero... that should be fitting. After all nobody is left at least not alife. I am alone and I get a headache from having literly nothing to do. Why am I like this?

    Reaper was on a mission, and a fairly important one, too. He was to go undercover as a mortal, find the anomaly known as Geno CQ, and kill him. Easy, right? ...It was definitely not as easy as he thought. Safe to say, he gets a bit... distracted from his initial goal. tldr: amateur dumbass reaper x constantly on the verge of death = surprisingly good romance Ships: Afterdeath, Errorink (background), Bad Sans Poly (background), Dreamberry (background). Only the Bad Sans Poly is established at first, everything else develops over time!!! Warnings: Gay Swearing Death (duh) Injury and blood Bullying Future Lemon (will change rating to mature when I post that part, I am the same age as Geno and Reaper here so I'm pretty sure it's ok for me to write it) Poly Cover art from thedanniewannabe on Tumblr :>> Writing by me (obviously)

    [This specific version of soulmates tattoos was from BubblyShip's UndertalexCreepypasta soulmate au, at least I saw it from her first. Basically you get a tattoo on a part of your body that represents your soulmate. Like, if your soulmate loves peppers you could have a pepper tattoo] {Warning: mentions of abuse, specifically child abuse. Doesn't go into a ton of detail, but it's still there} (Also this an au where Geno, Error, and Fresh are biological brothers, and Reaper, Cross, and Ink, are adopted brothers) Cross, Ink, and Reaper were brothers. Not by blood, but they were still brothers. All of them had tattoos on their bodies that were ignored. They lived in a small house in the woods near a beautiful city, none of them unhappy about their situation. But when three other brothers move to the town near the woods, their lives become very different. What will happen to the ones who Don't Want Soulmates? {description and title still a work in progress, so be ready for it to change. I will put an AN if it does change}

    Nightmare is well acquainted with a Cafe that is slowly rising in popularity. Unfortunately, that means he can't visit anytime he wants now. My one and only Sanscest fic, gift for a friend. Does this count as Sanscest if Nightmare isn't a Sans?

    Born in a void, devoid of all life, Glitch Gaster had nothing. He had to watch as other Au's got to experience lives and outcomes.. While he had nothing. He loathed to have what they had. One day, Glitch Gaster witnessed the power of 'OverWrite'. He became obsessed with the idea of true power.. The idea of becoming so strong nobody could oppose him. He wanted a world of his own.. But not just that. He wanted more.. MORE POWER. He wanted to become god of a world. So with Inks help, Glitch Gaster created his own masterpiece.. the 'Glitch' button. Using it, he created a world of his design. A fake world.. With nothing real in it. All to be his plaything.. To satisfy his hunger for more power. But not everything goes how you want it to.. One of his creations suffers a malfunction. A glitch in the code.. And suddenly. He can feel, see, hear.. He's.. Real? But with a power hungry god ruling over his world, can newfound sentience really overpower raw strength when your whole life has been a lie?

    Some short stories that feature my favorite Undertale AU characters! It's probably going to mainly be about Nightmare, unless I start getting requests for other characters. This is really just a way for me to 'publish' the little things I write that otherwise would just stay on Discord. As the title implies, expect a collection of mostly unconnected short stories without any particular linear timeline. These are written at different times on different days and aren't meant to connect with each other like a normal book might.

    O hearken to the Paean of the Stars! A symphony sung by a choir of countless voices, with hope and love, kindling in their heart. Or delve into the shadows that grew beneath their brilliance for those secrets left untold. ⊹‿̩͙⊱༒︎༻⟡༺༒︎⊰‿̩͙⊹. The corrosion, a deep-rooted interdimensional plague that defies the restrictions of time and space, sought to tear down the multiverse into nothingness. In response to this, the Stars shone down upon the valiant from diverse realities and demigods, the Pillars, who work tirelessly to protect the souls of their ill, crumbling multiverse. Though they must first mend the discord between those who uphold conflicting beliefs before they tear each other to pieces. Time is running out, and their imminent destruction does not heed to whomever upholds the rules.
