    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!

    A human... An infant... Left in a tattered basket... Left crying in a cushion of golden flowers... Left only with a blanket and a locket bearing her name... (Y/n)... Raised by Asgore, spending her life in the ruins... She was bound to made many wonderful new friends... But... What if one... Is no ordinary friend? ... |{A/n: This book (at least the first few chapters) was slightly inspired by EightTheKat's comic 'The Seventh Soul'. Unless specified by me, none of the art contained is mine. Undertale belongs to Toby Fox. Underswap belongs to Popcorn Pr1nce (i think). Also the first couple reads are probably from me rereading this cuz I do that XD Also, updates will be slow, so I apologize in advance.}|

    This is from a great fanfiction called "A Trio of Misfits" from Sabinarius. It's a really great story and if you haven't read it, I strongly suggest you do. I don't own anything. Not the story. Not the characters. Just the art.

    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'.]

    Shattered had ruled over his multiverse for ages, having long since plunged the world into a neverending pool of toxic positivity that fed him well. But one day, he was betrayed-overthrown, imprisoned, and banished to a different multiverse, never to return. Well, that was fine! He could just make a new empire! He- Wait, he just..did he just stab his counterpart- Oh. Oh, shoot, he'd just killed this world's Dream. These characters are not mine!

    Picture not mine credit to artist! This story is about Dream who never knew anything about Error but when they spend time together and over come obstacles, maybe just maybe they can be more than friends... This is my first story so it's full of cringe

    OLD WRITING Rewritten version on AO3 under the title Home Sixteen-year-old Sans is "peacefully" walking through Waterfall, feeling the rain on his bones. He's not exactly pleased with the situation, but he can't afford to care. But to his surprise, another skeleton kid, slightly shorter than him, approaches shyly. Enjoy and read well ✨ Word Count: 9,351

    A series of one-shots (that may become miniseries in and of themselves), mostly focused on everyone's favorite glitchy bean, Error! And by Error I mean my own version of FGoD Error (Credit to harrish06 for bringing this to light!) These stories all are 'what if' stories, and most are legit stories. Some my get a little (read;a LOT) crazy, but hey, that's the whole fun of it! This is my first story, so I welcome ideas and advice. All flames are YEETED into the void. The cover is not mine (I'm nowhere near that good), credit goes to the artist! Error belongs to CQ, a.k.a. loverofpiggles (I think I spelled that right?) All other characters belong to their creators Undertale belongs to the crazy genius that is Toby Fox!

    When Error tries to destroy Underswap Ink was a bit late saving the rest of the AU but made it on time to save Papyrus and Sans and he takes it into his hands to protect them from Error and they move into the antivoid with him and Error what will happen :P (Ink was only being shipped with Error and I took it into my own hands to change that I don't really support the ship I just felt bad for Ink he was only in one Ship)

    Dream and Nightmare weren't always the best with technology and modern conveniences. In fact, there was a time when they hardly understood them.

    A series of UTMV Oneshots that are mainly unconnected to each other unless stated so! These have been collecting dust so yeah. (SLOW UPDATES) My writing isn't the best, and I know this but I am improving and honestly just need something to do. Some will be from my own Multiverse, but there won't be many. {MISCHARACTERIZATION! Personal HEADCANONS!} I will always update on the weekend, but I don't update often. Just that it's usually on some random weekend. (Mainly Dream/Drink somehow, at least I'm pretty sure it is.)
