There in a faraway AU was a land full of different souls with different skills. It wasn't long until hierarchies formed and wars broke out. But while most gained ranks through wealth, others used power or skill. Soon things settle down with several kingdoms forming with very different leaders ruling them. There's Lord Death himself assisted by Geno, an "advisor", then there's King Dream ruling with his loyal friends after Queen Nim's land was broken in half. King Nightmare rules in a land blessed by the moonlight with a fearsome reputation. But then word starts to spread of a fourth kingdom forming with a mixed reputation. A large beautiful land with expert craftsmanship and wonderful harvests but also a land where all residents are intimidated by a ruler that sneers at the title of king? Whose source of power is a...thread? Now that's something the rest just have to see...to meet and possibly gain the favor of. Not that this ruler, Error, will make it easy.

Formerly known as, "I Became the Forced God of Creation". !!STORY COVER IS MINE!! What if.. Error isn't a forced god but Ink is? What if Ink had enough and committed death and chose someone to be the next Ink, the forced god of Creation? What will happen next..? Will they end up like Ink or.. A brand new fate and destiny awaits..? (FGod concept which is not mine and this story is an original idea of mine. Undertale doesn't belong to me nor any of the characters shown in the story. That's all thanks for reading.) (FGod Ink belongs to me, FGod Error belongs to Harrish6.)

They fucking reek. That's the first thing Sans notices about these animatronics. It doesn't take long until he notices other things about them, and after a lovely little meeting with the companies lawyer, Sans is blackmailed to keep working for the company. He thinks it'll be easy to collect some evidence and get the company to sink. It's... not that easy. With learning how to coexist with those who tried to kill him previously, every layer of the mystery he unravels only opens more and more questions. Sans is just trying to survive. --- Undertale x Fnaf crossover, updates the 1st of every month.

After the party, Blue and Lust started to hang out more. Meeting up every weekend or whenever they were free. It was incredibly obvious they fancied each other but both of them were too clueless to notice the feelings they reciprocated for each other. And here ladies, Gentlemen, and non-binarys is the slow-burn fic I always wanted to write. ~love Author

(I do not own Undertale or this picture, they belong to their respectful owners. I only own this story and any OC's.) Waking up as a ghost makes one assume the worst. For example, having died and not being able to pass on. And another way for one to panic about waking up as a ghost is not being able to remember who you were and are. When she woke up as a light pink ghost, she assumed she died. When another ghost comes in and calls her 'Happstablook', she straight up giggles in shock later turned to crying. After leaving the house, she could no longer deny it. She has somehow had become Mettaton before he himself became Mettaton, years before even as she found out she is considered a child still. She broke down, not understanding why she is now in this position. She couldn't remember much about herself, but she is sure she fell asleep as a human. It took a while before she finally had a plan of action, as shaky as that plan was. She is not Mettaton, but she will make his dream come true in her own way. Her company will be different, she will treat people different because her SOUL has a very different core trait. She is not like Sans, when the time comes she is a wild card. She does not follow a script and that makes her one of the most dangerous Monsters there is to the human child. Even before the Determined child came, before she took the name Mettaton, she broke so many rules and laws. "That's cute." The genocidal child blinks at the sudden giggle. "You think I am going to aim for your SOUL?" A head shake. "Honestly it is easier to snap a neck then care for HP. Unlike the others I don't plan on fighting fair if lives are on the line." The child only had time to gasp before they fell limp, dead from a broken neck. The next time they come, they are shocked when it happens differently. This robot was not playing by any rules at all. And that scared and excited them beyond all measures.

(This is the rewrite/newer version of 'Healing What Has Been Broken'. I do not own Undertale, the characters, or the cover - they belong to their respectful owners and JuneTheTrickster made the art based off of my new design for Erratum. I only own my versions of the characters, OC's, and this story.) Error, the Forced God of Destruction and Destroyer of Universes, formed by Fate and left to be the Multiverse's scapegoat. Ink, God of Creation and Creator of the Multiverse, created by Fate and the most loved out of the Multiverse. Yin and Yang, two sides of the Multiverse's balance. Without creation, the Multiverse would be empty. Without destruction, the Multiverse would become overcrowded and destroy itself. Neither side inherently good or bad, both sides that should work together to stabilize the Multiverse. Should. Yet, Error was so tired. Tired of the pain, the hurt, the betrayal, the endless cycle that seemed to go on forever. Where he was the villain, the insane Monster with no feelings, wants, needs or desires and Ink was the hero, the one that everyone looked up to and loved for 'protecting' them. Fate would not allow him to die. Forcing him into playing a role that he has grown tired of and hate. But, one day, Error had been able to take his fate and change it - making it into his destiny. Landing in this new Multiverse, the impossible became possible. Too bad his own Multiverse found him and wanted to ruin it all for him. Yet, this new Multiverse wouldn't give up Error without causing and fighting a war for him. Much to Error's shock. There was a reason Destiny chose this Multiverse for Error to land into. Healing might take some time, Fate might still be a issue, and it might be different from any other Multiverse, but it is more than willing to fight for one of their's. Error's old Multiverse is in for a ride once they find him, because this new Multiverse is more than a little blood hungry. Unstable Multiverse, meet Warverse.

She however knows next to nothing about bitties. it would be a real shame if 9 traumatized lamia bitties that need specialized care were dropped off at her rescue.
