Summary
For weeks, Error's schedule had been packed with different obligations and responsibilities. A promise to help here, giving his word that "he'd definitely see them then" there... His daily life became such a whirlwind of constantly running from one place to another, Error hadn't quite realized how much time passed. Before he even realizes it, six straight weeks pass by since he has seen his boyfriend face-to-face.
Yes, Error had barely time to think recently, but he knows that's not much of an excuse. Oh well, maybe they can have time to hang out today. Error's schedule has been inexplicably clearing up one by one all of a sudden...
It's probably nothing to worry about, right?

Summary
Найтмер был уверен, что сможет перетерпеть это ходячее бедствие до выпуска. Киллер был уверен, что найдёт подход к этой ворчливой ледышке и в итоге они подружатся. Два семестра взаимных претензий, колкостей, игнорирования и провальных попыток поладить – и вот новый учебный год сулит ту же пытку. Однако рождественский мороз, полупустой бар и пара недопониманий решают иначе, стирая границы контроля, обнажив то, что так тщательно пряталось под маской обоюдной несговорчивости. Алкоголь действительно становится роковой ошибкой: невинный спор и пьяное любопытство приводят к тому, что напряжение между ними находит совершенно неожиданный выход.

Summary
Echo did NOT break up with his NOT boyfriend, but he's still not okay. Meh, he doesn't really get to have nice things anyway. Not like it’s a big deal, he’s completely fine!
This fic contains: Mentions of self harm, manipulation, mild gaslighting(?), some very mild religious undertones maybe, desperation, depression and a LOT of weird talking flowers. Like Srsly they wont shut up. And dub-con mature content in the first chapter. No actual explicit smut tho. I think. I hope. This list may be changed or added to. Stay safe and read at your own risk.
Should update every Wednesday if I can help it (read: if I don’t forget) until I run out of complete chapters

Summary
La realidad no es más que un tejido fino sobre un abismo de estática, y alguien —o algo— ha comenzado a tirar de los hilos.
Tras la aparición de una fractura en el tejido del multiverso, lo que comenzó como una misión de rutina se ha transformado en un descenso a la locura. Mientras los guardianes del orden y el caos intentan mantener una fachada de normalidad, los cimientos de la existencia comienzan a resquebrajarse. Fragmentos de recuerdos, lealtades fracturadas y una conexión prohibida amenazan con borrar la línea que separa la identidad de la aniquilación.
Dream y Nightmare custodian un pacto de silencio que podría salvar —o condenar— a todo lo que existe. Pero en el silencio, algo los observa, y la sincronía que comparten empieza a hacerse notar más allá de su voluntad.
Todo vínculo tiene un precio. Y en un multiverso donde la verdad es el enemigo, la ignorancia es el único refugio que queda.

Summary
Reaper is overwhelmed.
His wedding is approaching, his child with Geno is due soon, and the family business never stops demanding his attention. The empire practically runs itself by now, both the legal side and the criminal one, but Reaper is still the head of the family, and people like him never allow themselves to look away for too long.
As if that wasn’t enough, there are still his brothers. Ink and Error are chaos incarnate, impossible to control and even harder to survive. But his biggest concern will always be the twins.
Dream and Nightmare are getting harder to keep close, and in their world, one mistake is enough to lose someone forever.
So when an unwanted suggestion about strengthening their security appears, Reaper makes a decision.
Unfortunately for Nightmare, that decision comes in the form of three former assassins being handed to him as a wedding gift for a ceremony that isn’t even his.

Summary
The RougeRiddler's been named! Also there's a weird hole in the sky again! Finally several new enemies have reared their heads!
Warning: This Fanfic is not accurate to Undertale canon as the authors didn’t play Undertale when this was written and were 12. This is Book 8 of 9! This is the last complete book in the series! The next book consists of one complete chapter and one uncomplete.

Summary
Cross and Epic are the most legendary thieves in the whole world! But there is just one teeny tiny problem…that is actually…not…true, heh.
But it is okay! All they need is an opportunity to show the world what they are capable of!
And an opportunity is exactly what they got, all they need to do is invade a rich guy's mansion and steal an artifact that only existed in legends.
What could possibly go wrong!?
(Answer: a lot.)
Or, follow Cross, Epic, and a very questionable new addition as they try to build a name for themselves without getting caught, killed, or completely derailing their own plan.

Summary
Шла, шла и умерла. Мало того, что умерла как лох, так ещё и после смерти покоя нет. Без моего согласия запихнули в глючную задницу всего мультиверса! Мою любимую Ошибку, конечно, но всё же! Не хочу быть разрушителем вселенных. Работа эта неблагодарная, опасная. Так ещё и без зарплаты и отпуска. Идите все нафиг, я сбегаю. Пусть в этой мультивселенной хоть коллапс произойдёт от переизбытка мусорных вселенных! Мне плевать!

Summary
Being a creator themselves they hated the way that XGaster treated his creations but their wasn’t much they could do about it seeing as it wasn’t exactly real, but reincarnating into UnderVerse they were going to use this opportunity to beat some sense back into Ink, and make sure XGaster lost his life privileges and XGaster’s bitchass was going to pay, and his victims would get JUSTICE. But what was JUSTICE? And what was VENGEANCE? Could they make sure not to fall into VENGEANCE or would they even care if they did?
Also if they might be able to help out a pair of lovers along the way and see one of their favorite ships come to fruition, well, no one could blame them~
But can the others at least stop calling them kid!

Summary
Dream breathed, “You’re not going to win this,”
“I know.” Killer stepped back as his wrist was caught, held in the air as he tightened his grip around the knife.
Dream hummed in puzzlement.
“Then why try?” He asked, craning his head to the side as Killer attempted to push himself away from Dream’s relentless grip, failing as he did so.
Unexpectedly, Killer moved forward, until their bodies were almost touching each other. He leaned his head towards Dream’s ear.
“Because it’s addicting.”
