Fandoms: Undertale (Video Game)
01 Jul 2025

Summary
Error had spent a long time doing the same thing repeatedly. First, it was watching others that he loved go through the same pain while not being able to help. Now, it was to continuously fix all of Ink's mistakes regarding which worlds are fit to continue to exist.
However, all that changes when he happens upon Cross's world fresh out of its destruction, throwing a monkey wrench into how he had gone through life up to this point. With Nightmare's help, Cross is shaking up Error's life, but Error doesn't actually mind it as much as he thought he would.
Will Nightmare, through Cross, finally be able to convince Error that he, too, deserves a happy life and home? Is there something more behind Error's feelings for Cross? What is now waiting for them with all the new changes and opportunities? Follow them all as they answer all of those questions and more.

Summary
Error's anxiety spiked with every passing second on the save screen, the void offering no sign of his brother Geno. What was supposed to be a routine weekly visit, laden with snacks and multiverse stories, had turned into a nightmarish scenario. Panic clawed at Error's consciousness as he scanned the emptiness, desperately searching for any trace of Geno's presence.

Summary
Error has lived a long and lonely life, doomed by fate to bad the dreaded destroyer of universes, whose home is the endlessly maddening Anti-void where time nor space have meaning. It is a monotonous cycle of Undernovella, destruction, and avoiding the Star Sanses.
Until one day, when a Sans uses his machine to hunt down his Gaster and tears a crack in the realm Error calls home, he makes a choice.
What if he goes down there and makes a casual visit to that Universe to cure his boredom?
Surely this wouldn't change too much about the future of the Multiverse, right?
(It absolutely does, and he never once regrets it.)

Fandom: Undertale, Undertale (Video Game)
06 Jun 2019
Summary
Every Sans in any au knows who Nightmare is. Most know his story. Others knew his reputation. Inky and Dream constantly spread word about this so called 'dangerous' and 'emotionless' skeleton. But what do they really know about Nightmare?
What if Nightmare wasn't completely emotionless? What if he has someone he cares about? Someone he takes care of like his own children? Let's take a look at this skeleton in a different light shall we?

Summary
“What are we going to do?” Miles whispered the question into the air, sitting down heavily on his hammock. It swung and bounced a little because of the elastic webbing holding it up but didn’t flip. “It’s like we got everything we wanted and everything we didn’t all at once. I mean-” he turned to look at Shadow imploringly.
Shadow didn’t speak, letting his companion get his thoughts out without interruption. Shadow used his webbing to cuff Error’s limp hands together in front of his body.
Miles took it as a cue to continue. “I mean, we wanted this! This was the goal all along! We wanna be able to save people, not just sweep away their graves.” His voice got quieter. “But what can we do with them? With him?"-
Rejected by the primary "guardians" of the Spider-Verse, an alternate Shadow the Hedgehog and Tails (Miles) commit to making a place for themselves in a separate part of the multiverse as they watch over the expanses of worlds in their domain. What they certainly weren't counting on was taking anyone else into their tiny, close-knit group. But here they were. A couple misplaced Sans's later and their numbers went from three to five quicker than they could say "Arachno-Humanoid Poly-Multiverse."Series
