    If given the chance, would you start over? After falling into a timeline where nobody was murdered, his mother never died, and his father was never erased, Sans should be ecstatic that he has a second chance with his loved ones. But there is no denying the trauma he'd been through, either. Everyone is supposed to be dead, after all. What if Frisk comes back to take it all away again?

    In a timeline that no longer exists, there was once a version of Undertale where everything followed a familiar path... until it didn't. She doesn't use a name anymore. Most just call her "Unknown." Once, she was the Sans of her world-lazy smile, quiet jokes, and a sharp awareness of timelines. But her universe wasn't reset... it was erased. Torn apart by Error Sans, leaving nothing behind but fragments and echoes. Unknown survived-but not whole. Now she drifts between broken AUs, a glitch in existence itself. Her humor is quieter, colder. She remembers things she shouldn't, feels timelines that aren't hers, and carries the weight of a world that no one else can mourn. She doesn't fight to save timelines anymore. She watches. Because when you've already lost everything... what's left to be afraid of?

    Chara will never forget the day their life started over. It was like everything in their past suddenly became worlds away, the memories clear yet unreachable. The entire universe had shifted. Except it really hadn't. The world kept spinning; the sun still rose in the east and set in the west. Chara had followed that sun to the demise of their old life, and they were guided by it in their new life. They picked a direction and walked in it, until some other force stopped them, until life began again. This new life, this new world, couldn't be more different from anything they had known. --------- Or: A universe where there were never any human mages, underground, or reset possibilities, just a war between humans and monsters. Chara tries to survive in a small town near the border of monster and human territory while torn between which side they belong to.

    Remember when I said I was bored in that little 'Heyyy-' chapter of the story I made called "Holographic dreams"? (If you don't know what it is, go check it out, it's awesome.) Well...I made an AU of it. Yeah yeah, I know there's only seven parts in the main story, but this is just for fun. Who knows, maybe this story'll get bigger than the original? Eh, big dreams. Anyways, in this version, Holo is now a boy, and is extremely arrogant. Pretty much an asshole. He claims to never be scared of anything..I'd say more, but I don't want to spoil the main story..or this one. But I c a n say that this story will be much different than the original story. Maybe. Possibly. The only character that belongs to me is Holo by the way.

    Art Book Number 3! ...My other art books make me cringe so, this is my third and most recent! This art book has been in the works since December of 2019, and- I myself feel like I've really improved since even mid 2020. So uh... Once you see those Mugman and Cuphead drawings, that's where I got more 'serious' with my art ^^' I'll take requests for book covers, fanart of characters, and just drawings in general! It may take me a bit of time to finish them, though, so please keep this in mind. This book includes fanart of~~~! Steven Universe Cuphead/Mugman My baby, Preshin * BATIM (mostly my/a friend's version of Sammy Lawrence) * Some FNAF and Sonic the Hedgehog Started: Around the start of December 8th, 2019 Finished: -unfinished as of now-

    Hi there, if by any chance you've happened to stumble across this book, this is me, creating a storyline for my own au which I'll be mixing up with some other familiar ones! The au began on my Instagram where I created an OC called Spooks, who in my au, is Sans and papyrus' older sister. I'll explain more in the beginning chapter of the book. Spooks belongs to me! Sans and papyrus belongs to Toby fox (this variant only belongs to myself) Ink belongs to Comyet Error, Fresh and Geno belong to Crayon Queen Fell belongs to underfell community Blue belongs to the underswap community (as does his brother and any others I mention from his au) Reaper belongs to Renrink Goth belongs to Nekophy Paperjam belongs to 7goodandgel Nightmare(mentioned briefly) belongs to joku If you get the chance, it would mean a load to me if you check out my Instagram (itsjustellii) where I post about undertale and my Au quite often! Enjoy!
