Summary
The weather was colder in Snowdin- far past what it should be for the AU's normal- but it was simply a heavy winter. Nightmare had long put aside the question of seasons underground, he could never get the time or resources to properly look into it and only knowing a little bit of it would drive him mad. Though he hid in the treeline, there was no doubt in his mind that the starved monsters had already taken notice of his presence.

Summary
"Give it up Nightmare!" Ink shouted, the first thing Cross perceived as he closed his portal behind him. Blue and Dream were to his right, both sporting determined expressions straight ahead. Cross followed their gazes, instantly locking onto the dark form of Nightmare. They were on the main street of Snowdin, the crowd that frequented Grillby's now in front of the bar also staring at Nightmare- and the Stars. Nightmare- who looked the worst Cross had ever seen him. His eye was only half-open, his hoodie and shorts torn and covered in non-monster dust and mud. But his face was even, eyelight constantly moving between the Stars- but not Cross. He hadn't looked at Cross in months, though Cross could barely look away from him. Nightmare didn't respond to Ink, just blinked slowly as if just waking from a deep sleep.

Summary
And Nightmare's smile was back, content with whatever conclusion he had drawn, “How about a meal, together. I’ve always wanted to be more involved in… what makes you unique.”
“What do you even mean, involved?”
“Whatever you want it to mean, darling.” He offered his hand, after a moment’s hesitation, Fresh took it. He seeped between its bones.

or, Nightmare helps a sick Fresh take over a host
This fic was written for Fresh's 2026 birthday-- Happy birthday Fresh! Its birthday does not feature in the fic.

Summary
Despite his casual air, Shouta was laser focused. He took in and processed information in a snap. Usual things, like the visual appearance of the room he was entering, but also things unique to Heroes and things unique to cats. The room had narrow dimensions, cold tile floor, pale blue walls, a bed in one corner and a dresser in the other, and no handle at all on the inside of the door. It smelled of laundry detergent and disinfectant and the faint but unmistakable scent of blood and medicine. There were boxes pushed up against the floorboards, what looked like children’s toys, dolls and stuffed animals and coloring books, all in their original, untouched packaging. There was a little girl kneeling on the bed, fear on her face and pain written in every line of her body.

Sans Tumbles Through the Multiverse Headfirst by PapilioVolens

Summary
Sans has finally managed to fix the reset issue. It only required the deletion of a vital character. The barrier is broken, and time finally begins to move again. Recovery is slow, but Sans finds solace in his dreams. By the time he realizes his dreams of other universes are real, he has already grown attached to their residents. And then he's attacked at home and is thrust into the multiverse proper. He finds things very different from how he expected. His old friends don't recognize him, and some of them appear suspiciously older.
It doesn't take long before Sans starts to suspect that he may have a larger role in the multiverse than he predicted.
I wanted more Classic adventures through the multiverse, so here's my contribution. And cause I'm me, I can't help but try to make a saga out of it.
Features Classic being Classic, strange multiversal mechanics, and a sleep-deprived author who 100% knows what they are doing
Important note: NOT on hiatus, just slow and life being a bitch XD

Summary
Mind him, it isn't his fault Murder decided to be a bitch this early in the day.
Killer—
Doesn't answer.Water ripples against his knees as Killer moves, not just testing the water or rubbing away at Sans’s legs but— he…joined in.
The silence is even louder than the screaming of the dead.
Or, 5 times Horror Sans noticed they're sharing bath times, just hanging out. And 1 time someone else familiar took the role.
