Summary
In a world divided by blood and magic, four Sentinels stand guard over Auravoria—an alliance-born kingdom forged from the ashes of war. Revered, powerful, and trusted by the throne, they are protectors of peace.
But peace shatters when an assassin crashes the royal banquet. The Wolf—Obscurith’s most feared weapon—emerges from legend and strikes. He is captured. Shackled. Silenced. And nothing is as it seems.
Now, in the court that fears him, with children who cry for him, and Sentinels who would rather see him dead than beside them, he must unlearn everything he was made to be.
And maybe—just maybe—find the family that the flames didn’t take.

Summary
Sans couldn't believe he just did that! Stupid, stupid, stupid! When the Dean was going to refuse to give him the job because he didn't have a human partner, he lied straight to the man's face and said he did! Now he was expected to bring them to a facility party to prove that they exist.
Where was Sans supposed to find a human to 'date' him in a week? It's not like a human willing to spend any amount of time with him was just gonna fall out of the sky. And if they did, they most likely would laugh in his face about pretending to be his partner.
"Hey, Sans. Did you get the job?"

Summary
Waking up buried in snow, alone, and with no memories but basic common sense?
Check.
Seeing numbers, words, and broken code floating around every object and surface?
Also check.
Looking like a walking system crash—with one eye red, the other computer-blue, and a body flickering like corrupted a light?
Triple check.He doesn’t know who he is.
He doesn’t know what happened.
And most importantly...
He doesn’t know why everything feels like he shouldn't be alive.Everywhere he looks, the world speaks in code—and he can read it like instinct. Names, stats, system files, broken timelines. And yet, the more he tries to remember, the more he feels like a mistake.
Note from the Me:
This is my take on Fatal Error—a much more none canon, wandering version of him. He’s not fully canon-compliant inn terms of power and has a different origin and personality. It’s a reimagining: glitchy, lonely, and filled with questions, bad puns, power and some more bad puns. -

Summary
Sans tries a new strategy to save the underground from the being trying to wipe out all of monsterkind. This backfires tremendously when a human from the real world (who doesn’t even know about Undertale) gets transported into his universe. Will this result in friendship, a game of cat and mouse…or The Absolute?

Summary
Using Frisks Soul, Asgore manages to bring down the Barrier, in the process absorbing the souls and becoming a being of unfathomable power. Using a monster army and his newfound strength, he takes over a town at the base of the mountain.
Monsters become the reigning power, and a human slave trade blossoms in "Overground" (so named by Asgore). Monsters own humans as butlers, pets, and entertainment.
Sans never thought he would personally own a human servant, but after a chance encounter, he has to face his worst fear - living with the same creature as the one that haunts his worst nightmares.

Summary
Monsters are free, and Frisk is safe and sound at home.
It feels like fairy tales are real, though a rough break-up after eight years of marriage quickly sobers that thinking.
With the break-up follows a proposal straight out of a steamy novel: share a room with a man you've just met, while you get back on your feet and work on the process of finding a new place to move into.
Turns out, the guy who smells like grease and beer from how often he visits Grillby's is a lot less romantic than you would think.
And it's precisely living together what gets you to know all the icky things about him.
Until you end up falling for him with each nice little thing he does, and suddenly...
It feels like all those icky things start to matter less and less.
More so, when things take a sharp turn and you're in the middle of a gang fight, helping him however you can despite not knowing what you're signing up for.
Overlooking details like bloody clothing, chipped teeth, and reports of missing people on the telly make seeing him drinking straight from the milk carton a much more tolerable offense.

Summary
Pain flared on his right shoulder, blossoming sharply and spreading through his chest and down his arm quickly. The force knocked Cross down to his knees, and he had to brace himself with a hand so as not to collapse fully.
Uncontrollable tears streamed down his face. Cross couldn’t move his arm, the pain was almost numbing. He guessed his shoulder had been dislocated, and his clavicle is at the very least bruised. The realization made Cross’s mouth water and eyes well up with more tears.
Cross has to physically restrain from curling in on himself and placing his hand between his legs.
(or; cross is a masochist—the fic)

Caffeine and Capitalism by WritersGonnaWriteThings for MaddieMare

Summary
Cross didn’t ask for this. He didn’t ask for freelance taxes, interdimensional audit threats, or a suspicious 1099 from Dust. But it’s tax season, and the only place with caffeine strong enough to keep him from snapping in half is a cozy café run by a chill barista named Ccino.
Ccino, it turns out, is terrifyingly good at taxes.
Cross is not okay about it.
