It's over.. Glitch gave his life to end everything. It's been months since that fateful day.. But somethings off. People are beginning to forget the fateful events of "Under!Glitch".

The world, where maybe the monsters become smarter than the humanity.. That will bring the twist much more sweeter.

An apple rots. Paint dries up. Blueberries turns sour. A flower wilts. A blade shatters. ~~~~~~ The war is over, the bad guys won. The stars sanses had disappeared long ago, for reasons no one knows. Now the multiverse is crumbling, the balance being tipped to far to one side. Universes are dying, not just by the hands of the skeletons that now rule over. People considered important were moved to Dreamtale, now a ruined city that's been made as the capital of the multiverse. Summers grow cold, there are no leaves to fall in autumn, winter is barely survivable, and spring has been all but forgotten. It must be fixed. It must be saved! But is it already too late? It feels that way to most everyone. Is this distopia what was meant to happen to the multiverse and it's people? Is this what was wanted by fate when the first universe was made?

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.

Nightmare is well acquainted with a Cafe that is slowly rising in popularity. Unfortunately, that means he can't visit anytime he wants now. My one and only Sanscest fic, gift for a friend. Does this count as Sanscest if Nightmare isn't a Sans?

Yeah I gained an idea and stuff so things will be different even personalities and everything you can think of :)

What the title says. Most will be UnderTale/UnderTale Multiverse but there will be some crossover ideas, other fandom things, and non-fandom ideas. These ideas are up for adoption, but please credit me and notify me that your using my idea.

Fate, Destiny, Luck, Time, Life, Death, Chaos, and Balance. What do they have in common? They are all beyond our grasps, we can never tame them, they are uncontrollable. We do not control them they control us and- T̸i̴M̵e̵ ̵S̷t̸O̷p̷ ̵Y̵a̸P̷p̵I̶n̵G̷ ̴S̵o̵U̷n̶D̵i̸N̴g̵ ̷L̴i̶K̵e̴ ̶S̷o̶M̷e̴ ̵A̵p̴O̶c̴A̷l̶Y̸p̷T̵i̸C̷ ̵N̸a̷R̶r̷A̴t̶O̴r̷ ̸A̵n̷D̷ ̴J̷u̴S̷t̴ ̸G̸o̴ ̷O̴n̵ ̵A̵n̵D̴ ̵E̶x̵P̵l̴A̷i̶N̵ ̵I̵t̶ ̶T̶o̵ ̶T̷h̴E̴m̴!̵. . . . *sigh* ..very well Chaos this- IS AN ASK AND DARE BOOK ABOUT US DEITIES! ...Would anyone else like to interrupt me? It's okay Time I'll take it from here, like Emotion said it's ask and dare about us, enjoy!

After Nova's defeat, Blue and the others are at peace once again. However, it doesn't last long as beings that appear similar to them start attacking. They are said to be from a different timeline and are causing chaos in other realms and timelines. Blue then must join forces with her friends to go around the multiverse and prevent an multiverse threatening war. Co-Written by Piper.

So it was just an idea that popped up into my head. Things won't be the same in this au, possibly different personalities, different beginnings Etc

He's just trying to get through his day. (Ink Sans fanfic)

Huh, and here you thought you escaped the Sans'. . . oh well looks like your back. Except there's a different series of Sans' now. And the multiverse you're in, is obviously way different than the last one. Your 3 friends, Nira, Aphroditey, and Alexis, have been dragged along this time.

Error, like any FGoD Error, is tired of his job. But he isn't at his limit so far. Everything seems normal for him until things start to change and go wrong. I'm not good at descriptions.

The first book in Brianne and Writemyfanfiction's The Six Human Souls Series, this is the untold story of Cecil the purple soul, first to fall (after Chara). *Underverse/Multiverse fans this is extra special for you as there are scenes with such content. Do note however that you won't need an understanding of the multiverse to enjoy most of the story*
