    Bill is a giddy, excitable skeleton on the outside. But, behind that façade is a normal skeleton that has too much to hide. When Nightmare calls for a gang reunion, Bill jumps at the idea. It had been over a decade and a half since he had left the gang and he wanted to catch up with some old friends. What he didn't know was that he would meet someone entirely new. They would seem to go well together, like two pieces in a puzzle. But then he got attached. He just HAD to get attached. (Description changed to better fit new plot directive) The book 'I want to help you' by 13TwinklingStars inspired me to start writing this, and then I went off on my own plot. Still, huge props to them for making that, it's an amazing book. Epicest ranking so far: #32 in 'sanscest': 7th October 2023 No.1 in main ship: #1 in 'Bill404': 25th June 2023 Also a cool ranking: #60 in 'Insomnia' (Error x Dream): 29th March 2024 Also pretty funky: #109 in 'Inksans' 25th June 2023 Daaaaaaaamn: #204 in 'Nightmare' 4th February 2024 DAAAAAAAAAMN: #403 in 'Undertale' (let's go) 18th February 2024 Cool number: #1000 in 'Dream' 18th February 2024

    "Every system has an error. I just didn't know mine was real." After a data breach ruins her career, Aira Menon, a withdrawn data analyst, moves into a low rent apartment block called Varma Residency. It's quiet, ordinary except for one door that doesn't exist. The tenants avoid it. The watchman denies it. But Aira hears knocking from the wall beside her room. Soon, her work files start rewriting themselves. Her name appears in corrupted logs. And her reflection begins to blink when she doesn't. As her sense of time fractures, Aira realizes she's trapped in a loop that shouldn't exist one where data merges with memory, and memory rewrites reality. Welcome to The Null Room-404 where data becomes memory, and memory becomes the experiment. My first attempt at a psychological thriller so errors might hide between the lines. If you find any, maybe they're part of the story... or maybe they're just mine.

    This is an AU I was holding onto for a minute, it heavily revolves around the Insomnia (Error X Dream) ship. So ya know, if you don't care for that then keep moving on. This AU will also involve a Ship child I made, there will be visual references of her and any other characters with designs unique to the AU. Anyways, this AU asks an important quesion... Can the Mulitverse survive without The Creator? Will it still be able to maintain balance without such a vital piece? What will hapen when two opposite ends of the spectrum of 'good' and 'bad' work together? Let's find out, shall we? And watch as a multiverse proves its strength without the influence of its Inky God. (Written on Wattpad & AO3 Only) THIS ACCOUNT IS BEING ABANDONED OFFICIALLY THANK YOU FOR READING, WILL WORK ON ON AO3

    This is Fgod error and NaJ, but with a twist. Error's family comes to, at least some of it. Blue is Blueberror and becomes known as Cobalt Swap Mistake and Error considers him a brother, Pixel(in the NaJ verse she takes a for, like her never verse form, I own never verse(my version, don't know if others share that name) and Pixel is my OC) is considered Error and Blue's sister and becomes known as Pink Pixelated Mistake. Error becomes known as Onyx Glitch Mistake. Error404 is their father figure and comes as well. A Button!tale sans is considered their younger brother and he becomes known as Clasp Button Mistake. A younger version of Asylum sans is also considered a younger brother, his name becomes Mind Asylum Mistake. Null and Void are also adopted and called Sky Null Mistake and Citrus Void Mistake. Alpha comes and is an uncle figure, he is called Alpha Multiverse Mistake and Error404 is 404 Alphatale Mistake. 404 becomes the sewing teacher. Cobalt, Onyx, and Pink register as triplets, and appear 17. Their story is that their father(404) didn't know about them and their mother(Basically Destiny) died. They were then taken by their abusive aunt(Fate). And that their father only recently found them. Sky and Citrus story is that they were abuse cases and taken in. Clasp story is that he was kidnapped and a psycho did his button eye and his family is now dead and the psycho as well. He was then adopted by 404. Mind had the story of having been a special mental case and is now mostly recovered and was adopted by 404. Ages: 404 appears in his 20s or 30s, Alpha looks slightly younger than 404, Cobalt, Onyx, and Pink are 17(physically), Mind is 14, Clasp is 10, Sky is 6, and Citrus is 2. All of them have tear marks. Cobalt has gold and blue tears, Citrus has orange, Sky has blue, Mind has yellow tear marks, and Clasp has red under his button eye and darker blue under his normal eye. They can all secretly use magic.

    404 had been alone for a long time, finally he got the courage to look for someone to love. he was visiting a old friend at the dream brothers castle when a yellow and black skeleton came along looking for nightmares time. The yellow and black skeleton seemed to be very flirtatious and clingy. 404 doesn't quite like it but maybe they might get together.
