    He knows he'll be dooming them if he falls, but he's tired, his body is breaking apart, held together on a higher being's whim only. He wonders if there'll be another to replace him. He wonders if there will be none. It's rather silly, really, since he won't even be around to witness that. The crowd, the rage and bloodthirst palpable in the air will ensure that. If he does not fall on his own, others will force him to. Or, in other words, the typical start of Error being forced to jump into the Void one way or another, in this case into the NaJ universe! The cover art belongs to irodimmatcha on deviantart(will take down if the artist asks me to)! Updates will be highly inconsistent. Edit: Now cross posted on Ao3 under the same username!

    Ships; - Errorink/Errink (Error x Ink) - Dustberry (Dust x Blueberry/Swap) - Kreme (Killer x Dream) - Crossmare (Nightmare x Cross) - HorrorLust (Horror x Lust) Trigger warnings; - Self-harm - Eating disorders - Violence - Sexual scenes - Strong language - Mentions and suggestions of rape After ending their fake relationship, Ink and Dream's friendship is tense and unhealthy. It doesn't help that the Multiverse disapproves of their breakup, and Nightmare has grown stronger thanks to the negativity that stemmed from the event. However, things start to turn around after Ink and Error's 'friendship' takes a turn for the better as they realise their feelings for each other. But, what about the others? Will they eventually get together, or will their conflicting personalities collide with each other and make it impossible for them to get closer?

    In a world where the Queen brothers are separated both by fury and by horrible lies, Error finds himself in yet another wild chase with the law as he tries to help those he loves. In a world where all he wants is to see his brothers safe, Geno faces a huge challenge as both the brother of two criminals, and as a police officer. In a world where lies corrupt his life, Fresh's newly discovered emotions are conflicted between love for his brothers and hate for the many that have hurt him. [This story takes place when the CQ boys are adults, and is in no way reltaed to by other book 'No More Freshness'.]

    One day From the window of his workplace, Error notices Ink trying to sell a few of his paintings on the sidewalk across the street. At first, he thinks nothing much of it, an artist trying to make a living, there are a hundred of them out there after all, But he can't seem to get the artist out of his head though, and after what seems like a rough day for ink he decides that he could at least buy one of the paintings to help a guy out. It ends up almost like they have known each other, as they met before. It turns out that they had, when they were both very young, they had gone to the same school but were forced apart as Ink's family had to move away, and it seems like fate had somehow decided to bring them together once again.

    (if you notice any adjustments in this, I'm making small changes to it :p) This fanfiction is SUPPOSED to be written FOR FUN. Most of my fanfictions are usually me putting my writing skills up to the test. However, this one is a bit... Different. No explanation. It's an Undertale fanfiction. This is an Underswap fanfiction

    Basically a classic 'X Reader' you'd find on Qoutev back in the good ol' days. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Preferably, you would love to have roommates. Of course! I mean, who wouldn't want to have roommates when living in a SURPRISINGLY large house. You wouldn't necessarily call it a mansion.. more like a big house.. but you're getting off topic! Ever since you FINALLY finished college and moved into your late grandparent's old home you always felt lonely. None of your friends are in the new area you moved into and it was honestly just sad. Of course, you have no distractions and more time to appreciate everything around you and look for inspiration. You never thought that this would ever change when a sudden portal opened and a bunch of skeletons came in to change the way your life was supposed to go. You thank the universe for giving you new company, but pardon your language. "DAMN" was all you could say at the moment they popped out from the air. At least your not lonely anymore but... 𝗪𝗵𝗮𝘁𝘀 𝗴𝗼𝗶𝗻𝗴 𝘁𝗼 𝗵𝗮𝗽𝗽𝗲𝗻 𝗻𝗲𝘅𝘁? Maybe some friendships? Romance, maybe? Drama? Who knows. All ͓̽Y͓͓̽̽O͓͓̽̽U͓̽ can do is read to find out! (hope that description was good enough T_T . Prob will change l8r on who knows lmao)

    (Y/n) has always been different, but not in the different you're probably thinking. She's half human half monster. Half wolf to be exact. Her ears and tail are big red flags to the beast in her blood. Thank god she has the ability to hide them! The girl's parents were killed when she was a babe, but they saved her in the process. People used to chase her down to try and experiment on her or throw her in the underground. That all is avoided now for she found herself a foster mother. In school she takes precaution not to get close to anyone, only acquaintances allowed. But now, all monsters have been freed from the underground! They take refuge on the surface and go to her school. What happens when the ambassador, Frisk and a certain group of skeletons befriend her? Being around her they start to notice key things about Y/n's person and get suspicious. Most importantly, some begin to gain feelings for the girl. What lengths is she willing to go to keep her true self a secret? And with all this attention, how long before the others discover it? I guess you'll just have to find out. Undertale belongs to the annoying do- I mean Toby Fox All of the AUs belong to their lovely creators Of course you belong to the wonderful you!
