Summary
Today was not a good day.
Yet still, he was forced to stroll through the crowded Gyftmas streets, with a disguise in tow, just to keep Ink off his ass. All of this just to get some presents for his ‘allies’. Which he hadn’t even wanted to do, but apparently they had gotten him gifts every year and he had yet to return the favor, Killer’s words not his.

Summary
A story about Ink and Co. being space pirates and are living in the vastness of space.
Dream and Nightmare are immortal pirate captains, well known and feared among merchants and other sailors alike as Burning Sun and Kraken.
Ink, also immortal, is a member of Dream's crew and has been his closest friend for as long as he can remember.
It's a dangerous life they live with the guard hunting them down and trying to kill them.
So what happens when Dream and Nightmare get a call asking for help from the very guards that want them dead, offering a full pardon for their crimes if they do.
All they have to do is catch someone who is known as the 'Destroyer' and bring them in, so they can be dealt with permanently.
Problem is, no one knows who that is.Series

Summary
Doomsday prep has always been necessary in my opinion. If not for your time, then for another's time. So I got married young, to a much older, much richer man, waited a few years for him to die (cancer, so sad), and collected that money like candy at a parade. Then I picked out a nice place for a bunker, and had that thing built in another few years. When Monsters busted out of the mountain nearby, turning some Humans into Monsters, I was only slightly surprised the government's decision was to fucking nuke them all. Now I'm closing the door, and I see people in the distance waving their arms, yelling. I should just close the door, I don't know them, but I don't think it's fair to leave them out to die.
Author's notes, kinda:
Gonna be just Horror, Fell, and Fell/Swap variants.
Characters like Sans, Toriel, Asgore, Frisk, and others are really only mentioned, except Horror Sans.
Papyrus variants are more like different people in this, than variants of the same person.
Also, I don't really like Swapfell Pap (Purple) so sorry, but he might only be there for drama, not for a relationship -
The Misadventures of Sans and his very Normal Skeleton Children by Olrethaz

Summary
Grillby looked down from his bar to a familiar skeletal face staring up at him.
Sans?
But no, for as disconcerting as the resemblance might be this was certainly not a cheeky comedian. If anything, the little one (where are the stripes?) was still, almost unnaturally so.
Huh.
He hadn’t remembered any other skeletons about besides the goofy pair, but there was no way that one of them (Sans it looked like) could have possibly hid the existence of a whole person; or perhaps he had, one he didn’t know he was hiding to begin with-
“ya know where Sans is?” an eerie voice rang and the room stilled, silence as Grillby felt a headache, the world began to spin and-
A cheek-splitting grin “he’s my dad”
Sure, but does he know that?
All at once Grillby was wiping down his counters closing up his bar without knowing how he got there. He paused, then shrugged and figured that he should probably keep some sweets on hand for future reference.
Or
Sans acquires more children than he knows what to do with. Papyrus is ecstatic, the rest of the underground decidedly isn’t. The children(?) are absolutely no trouble at all, if you can believe it.

Summary
What if the player never existed?
What if instead of Kris, Noelle fell into that dark fountain with Susie?
What if Kris has no association with the Knight and knows nothing of the dark worlds?
What if the soul that was desperately needed to seal fountains was Kris's and Kris's alone, yet the human is blissfully unaware of how desperately they are needed? Of the leadership fated for them?
...
Kris watched as Noelle walked out of the classroom with Susie, sighing softly.
Whatever. Honestly...they knew they should care more but...Susie never bullied Noelle anyway....
However...for some reason after that, Noelle and Susie completely disappeared for the rest of the fucking day!?!?! And for some goddamn reason when they came back Noelle is randomly seeking them out and Susie is acting weird as fuck, and they're somehow a lot closer??? And for another unknown goddamn reason Susie WILLINGLY asked to do their project.
What the fuck is going on??????
Whatever. They don't need to be a part of this bullshit. At least Berdly is just as confused as to what the hell is going on with their project partners.
