Summary
Several years after Error’s suicide, the Stars and the Council finally realise just how wrong they were about him. Their multiverse is falling apart. And so they decide to bring in an alternative version of Error from another multiverse.
However, they fail to take into account that he has absolutely no desire to fulfil his duties — he does not want to destroy. Even after persuasion, threats and manipulation, he does not change his mind.
Well then. For the sake of the multiverse, they were prepared to do anything. Even to turn the stolen destroyer into a virtual slave, who, under very real threats of a fate worse than death or torture, submits to their will.

Summary
Error is the (forced) god of destruction, Ink is the god of creation. Both are needed to keep the balance, but while one is loved the other is hated.
Ink together with the judges elaborated a plan to finally stop Error. A deadly trap. Impossible to escape even for the feared destroyer.
But someone is not following the plan. Things get out of control. Error gets out of control.
Although things don't go exactly as planed, and the results are more chaotic than they should. It still worked. Error was finally gone. Lost into the VOID, scattering across time and space.
But someone had their eyes on the broken destroyer for a long time, and they were waiting for this moment. Now they can finally act. And take care of their chosen child....
Error woke up at the sound of his own crying. What? What's this sound? Why can't he speak? Wait, where is he? Why can't he get up? ...Uh? Why is he... so small?...what happened to him?_________________________________
This story is inspired by 'Healing what has been broken' by harrish6.- fgod Error concept belongs to harrish6

Summary
The story officially begins when Toriel dies in her universe mysteriously. Gaster with his allies show up and take her soul remains back to his lab to save her life. Toriel then had DETERMINATION injected into her. Most of the DETERMINATION was collected from humans in multiple different universes. Gaster created the perfect solution to end RESETs and genocide routes that plague The Multiverse. A new kind of boss monster with the ability to utilize the power of the savestar. Toriel, who got reborn as Gaster's daughter in his lab due to a serious situation that happened, it was the only way to save her life.
Gaster embarks on his quest to bring peace and balance to The Multiverse. However The Savestar becomes corrupt, doing more than its intended function.
If the RESET function is over-worked, it will erase a universe. The more universes that are gone, the more The Multiverse dies. They explore every universe they're able to, attempting to fix the savestar and rid the ability to RESET, helping others and themselves.
Note: The AU is heavily in progress, unsure when new content will be published. Hope you enjoy what exists right now though.

The Violet Banquet by viridVerdancy
Fandoms: Undertale (Video Game), Deltarune (Video Game)
01 Jul 2026
Tags
Summary
The Violet Banquet (TVB) is the name for the main group RP event in which alternates from across UTDR multiverses are invited to an estate party. The prototype (TVB 0) ran in February 2025 on the anniversary of Muffet's Love Ball, and the first canon event was held February 2026, starting at midnight EST on the 14th and ending at midnight on the 23rd.
The special lore unlocked by special side-quests are exclusive to the namesake events hosted on the estate itself by Ridwan, but there are also mini-events throughout the year hosted off-site by the other staff. As of yet, the main events are annual, but they are available for backreading year-round to those in the Discord server (linked to in the pinned post on @thevioletbanquetutmvrp on Tumblr) with the archive role 🔑. This is an adaptation selectively transcribed from the chat logs for audience accessibility, edited for formal syntax and narrated wherever context provided by chat or channel descriptions needed to be readded.

Summary
Dr. Vendette is Southern Trebane Hospital's "Miracle Doctor." Her quick thinking, cool demeanor, and no-nonsense attitude make her the star attending doctor in both north and south Trebane. Her reputation professionally is glowing, but everyone who knows her personally has differing reviews. More people hate her than she knows. Regardless, her untimely death shocked the whole of Trebane, and no one can argue that the city has lost its miracle.
Upon her death, Dr. Vendette is not greeted by pearly gates or hellish fire but by a disembodied voice in a dark void. The voices argue over her fate, and she wakes to find herself facing a new challenge. The young doctor has become the antagonist in a dating sim synthesized from the multiverse of her favorite game, Undertale. She will have to survive being the villain many believe her to be. After all, that's what an antagonist is, right?This is a reader-insert! A better explanation will be in the author's note at the end of chapter 1, but I will say this is a writing experiment for some of the darker themes produced by my other story of a similar concept, "They Call me Antagonist, but I prefer Anti-hero."

Summary
Dread ate at poor Sans as he tried to find its source. Multiple stories spoke of a fallen monster whose tears were woven like strings, prophesized by dread. Before he knew it, Error raptured him, all in the objective to show just how wrong he was about humanity. Refusing to yield, it was now Sans's task to defy his captor not in a physical brawl, but in a philosophical engagement.
This work will be updated every 2 days until an arc is complete.

Summary
Partnering with Ink Sans was already chaotic enough.
Giving him a device capable of creating temporary AUs somehow sounded like a good idea at the time.
Then Error Sans showed up and immediately decided he wanted both of you dead.

Summary
Contrary to popular belief, monsters who die do get to the afterlife, even if it has a series of conditions to happen.
It is the God of Death's job to reap these souls and send them to their eternal rest.
Reaper knows this, as it's always been his life. That's why he is heavily confused when the essence of a dead being completely dissappears before his eyes.
His confusion turns to curiosity when he meets this same being years later.
Specially when it turns out to be the Protector of Universes.
