    Thanks for stopping by to see my first ever story. More information is on the first part of this book! Thanks again! (COVER ART NOT MINE!!!) __________________________ Error and Ink, the gods of creation and destruction have been enemies, clashing with each other for decades over the creation and destruction of the multiverse. However, Ink seems to be the only one who's been trying to get along with Error. However, Error really does hate Ink. Or so he thinks. Are they both meant to be enemies, or something else? Perhaps.. friends? _________________________

    (A/N: Nobody has ever done this before, and I have a good idea stuck in my head! I hope you enjoy! Also, you should check out Winx Club/Undertale if you don't know this yet. MagicalIsa.) The Magic Dimension has many inhabitants: humans, monsters, fairies, pixies, witches, wizards, sorcerers and the like. All of these were once at peace and unity, not a single conflict had happened. Well, that is, until trouble arrived when villains came along. But what if someone, who is as bad as those villains, appeared and sealed monsters under Earth? (PS: Not all images are mine! Photo credits goes to owners. Character credits go to Iginio Straffi and Toby Fox. Plot credit goes to Toby as well. Isabela, Kaye Felton and other OCs are mine!)

    Sans breaks the universe by managing a dodge at the supposed final battle blow during a genocide run. The timeline, the universe was broken. The only way to repair the damage would be a hard reset from Frisk, to restart the game from the very beginning, and so they do. But what happens when it isn't Frisk that falls into Mt. Ebott? A completely new soul of determination. Everything had truly reset. A pure beginning. ----------------------- Undertale belongs to Toby Fox™ The only thing I own is the cover art, character design, and story concept!

    On the verge of completely giving up on love, Ink finally felt the warmth he's been yearning for. While he stood joyful from the sudden proposal of his lover Error, he realizes his world is torn apart when he stepped inside the Queen household only to find out they're actually cousins. Refusing to believe the twisted truth, they desperately look for evidence that shows they aren't related, in hopes of having their families accept them until they call off the engagement. ---------------- ⚠️Fair Warning in the Info Chapter please read it⚠️ Goal : 1k reads (I doubt people will read this because of the plot lmao XD) cover art by me it sucks I know-

    There are basically no spoilers because I changed the plot of Undertale SO much that you wouldn't even realize it's a spoiler unless you've played the game. (I don't own Undertale or the characters other than Jack! I do not own any of the art or media in this fanfic unless I say so!)

    A regular girl? Yes. A gamer? Yes. Do you like Undertale? ♥ Yes. No. That's the human named (Y/N)(L/N), simple, kind and normal. Attends a normal school with regular grades and such, also with a small group of friends. Everything seems normal, right? But what happens if she or should I say YOU somehow end up into the world of Undertale? START? ♥ Yes. No. The picture used for the cover is owned by yukiko-onna in Deviant Art. http://yukiko-onna.deviantart.com/art/Frisk-584966455 And all the other pictures that will be and are being used are owned by their rightful owners. Undertale isn't and will never be owned by me. It is owned and created by Toby Fox. Thank You! <3

    Innocence had already been more or lost by the Dreemurr brothers, but the friends and memories they'll make along the way are certainly worth it. The question is: will they grow and learn from the pain and challenges along the way to get there, and also cherish the life, good times, and blessings they've been given? Disclaimers: -This novel is a story collection of the Wholehearted Saga AU, a canon-compliant/canon universe, post-pacifist timeline sequel for Undertale. To help enhance the experience, I HIGHLY recommend finishing the true pacifist path of Undertale first, or at the very least watch a playthrough of the true pacifist path before you read this story. -This episodic series serves as a sequel to Undertale's true pacifist timeline, but as a prequel to my previous work, "Wholehearted Half-Souls." Thus, the "Origins" collection is "part 1" in the Wholehearted Saga series, while WHHS is "part 2." -Each story is more or less stand-alone; you do not have to read the stories in the collection in order if you don't want to (even though I would recommend reading in release order). At the end of each short story, there will be an explanation as to why I wrote each work, and how it helps develop the world and characters for my magnum opus, "Wholehearted Half-Souls". -Mentions of real-life locations and phenomena are completely coincidental. -Cover was a commission from TC-96. She did a wonderful job. :) -UNDERTALE AND DELTARUNE ARE THE PROPERTY OF TOBY FOX. I DO NOT OWN THESE CHARACTERS NOR ANY PROPERTY RELATED TO THEM.

    Error and Ink are polar opposites. Enemies, one could say. But when the circumstances arise, it puts their newly formed friendship to the test. Will they fall apart and let their instincts get the best of them again? Or can they be something more?
