Summary
Apeirophobia: the fear of eternity; endlessness; the infinite.
—
Giving up and starting over feel the same sometimes. It’s difficult for Sans to do either when he can’t let go of the past. It’s difficult for Papyrus to do either when he doesn’t know what that past is, even when it’s rearing its ugly head.
Papyrus’s attempts to stop Sans from lying end up rekindling an old Connection, for better and worse.

Summary
“Quill!” You call him again, voice sharply spiked with worry. Your son stops an inch away from his prize in a whole-body flinch, shocked by the loud register of his name, and turns to look at you with wide eyes. As he pivots the ground beneath his foot squelches under the pressure and he slips. His foot comes out from underneath him, flying forward in a kick, and he flails backward. He falls with a gasp and a splash, ripping a cry of alarm from your throat.
This story follows you and your child as you explore the Underground and try to make a comfortable life down there, while also struggling with the fear and anxiety of being discovered as a human. You struggle with learning a culture while pretending to be part of it, learning to trust, and slowly come to terms with losing your surface life.

Summary
It has been ten years since the barrier was broken, and a small half monster gazes out over the valley from the edge of mount Ebott.
The entrance to the underground lays behind him, and echos of long past cry from the cave.
He steps to the edge of the gaping pit, and attempts to climb down the edge, but the earth crumbles around him.
Like the ones before, he falls into the darkness.
Unlike the others, he wakes in the silent darkness of the void. -

Summary
Free at last, Gaster fled upstairs. Grillby was left with the two rascals on his own for a few minutes. Since he was dressed already, he had to be a little careful to not provoke a suplexing spree. "You two don't need to worry about him that much, okay? He'd dealt with worse things than just some stuck-up assholes."
"Language..." Papyrus beeped, his usual enthusiasm nowhere in sight.
"And I promise, if it gets out of hand? We'll burn the entire thing down. Together."
In which Gaster and Grillby prepare for a ball, and the siblings have Opinions.

Summary
In the year 1923, a young lady is simply looking for solace in her day to day life, and making peace with her choice to move to the unforgiving Ebbott City, a place riddled with crime and violence. Eliza Black did her damnedest to avoid the underworld of the city, but fate had plans for her in the form of Sans Gaster, the mobster who ran it all. In a harsh and unforgiving world, Sans refuses to let go of the light he's found in her, and in a twist of fate, Eliza finds herself caught in his thrall... and it may just cost them everything.
TL;DR: a 1920's Mafiafell Fic! Hope you guys enjoy, this is my first work!

Summary
When Gaster stumbled home late that night, he already looked exhausted. And although he at least had the decency to look excited about Grillby being there, he barely managed to say hi to the brothers before he settled and fell asleep sprawled over him. Face buried in his shoulder, curled up just enough to fit on the couch, but still blocking any attempt at moving.
Like a cat.
Surprise! Gaster purrs.

Summary
They commenced in a dance, the only song was the one that played from their hearts as they stepped in time with each other. Their sways and movements were perfectly in tune as they moved across the snow, crisscrossing new tracks over the old, writing new melodies as their bodies moved.
It was almost practiced, and if anyone had been present to view it, they would have said the same thing. But they had never done this before, never once had they danced, much less practiced, yet the urge to do so had plagued Chara suddenly, as the minutes ticked toward midnight.
"I Like this dance," Frisk commented as they swayed, an easy smile on her face, "But I feel as if I've stolen it in her place."

Summary
You've been neighbours with the Skeleton brothers for years, and you've stuck around after all the stunts they pulled. Helped them learn the basics about humans as they did the same with you and Monsters. You were there when Sans almost blew up their home by bringing their eldest brother back from the void.
You're pretty open about how you feel and they know exactly how important they are to you. If that's one thing you appreciate about Monsters is that they are normally very straight forward about how they feel and appreciate the intent behind your words and actions.
But then the Mad scientist Duo that was reunited with the two older brothers were testing your little patience as they messed with the machine again and brought not 1, but 2 whole different versions of themselves and Papyrus into existence.
These boneheads are so lucky you're a persistent soul.
