Summary
With his mother gone, every moment Snowy is stuck with his father feels utterly suffocating. So he leaves for Snowdin, never to return.
But his circumstances are far from ideal, and he's forced to join a gang of delinquents just to have a place to sleep, each day pushing the limits of how much he's willing to be complicit with.
Yet who he ends up meeting there might turn out to be more than just a friend. Maybe there's more to life than just making it to tomorrow.

Summary
“You have wings!?”
It’s almost comical how much Dream’s sockets have widened. And, they somehow manage to widen even further as Ink reaches down, grabs a fistful of snow, and lobs it directly at Dream’s face.
Dream has wings. Ink is appalled that he wasn't told sooner.

Summary
A little bit of rest during her research could definitely hurt, yet her eyes began to shut anyway. The consequences to this were much more dire than Queen Alphys could’ve ever expected, and after an abnormal earthquake she finds herself stuck within the endless Multiverse.
And for some reason Sans is.. everywhere??
OR
Takes place right after the Alphys Neutral Ending, where a freak accident sends Queen Alphys - better yet, just Queen - out on a travel through the Multiverse.
P.S: Chapters will most likely be short, but to make up for that, updates will be as frequent as I can manage.

Summary
The Multiverse isn't as unreachable as one might think. Sometimes, all it takes is one aware person to tip the scales for another to find out about it. But when one isn't ready for it, returning to their own world is relieving and best for the psyche.
Humanity's thirst for knowledge is near insatiable. How far would they be willing to go to learn more about their new magical coinhabitants on the surface? How far would they go if they could weaponise their magic?

Summary
“it’s just…you keep acting like something horrible is waiting for you at the bottom of this mountain.” His whispered voice was calculated and obnoxiously observant.
Frisk chewed their lip and felt their nails subconsciously start digging into their palm. The last thing they wanted to do was ruin anyone’s excitement about the surface with their own anxieties. If anything, they thought they’d been hiding their fears pretty damn well.
“There are some things, Sans…” their voice seemed to start against their will, hushed and constricted. They put a hand over their heart, which was beating restlessly.
“…that I just can’t explain to you,” Frisk finished exasperatedly.
