Summary
Sans is conflicted by night terrors and vague memories from previous timelines gone wrong. While they're starting to become more vivid, soon he starts to notice deviations from what he's grown accustomed to and Papyrus does something unusual that changes everything.
With the River Person out of commission, Sans accompanies Grillby on a replenishment run through to New Home, all while wrestling with a feeling he just can't break about his long-time friend. As he gets to know Grillby in a newer light along with some changes that have come up due to past medical abuse, it's becoming more and more apparent that something or someone is interfering...
(This fic is pre-canon which will eventually progress into gameplay plot with some embellishment. Originally rated Teen, but has since been upped to Explicit for references to bad physical and emotional trauma and Sansby exploration. Smut/sexual content will have warnings at the beginning of any chapters and a brief summary in the end notes.)
IF YOU ARE A MINOR DO NOT leave comments on the nsfw/sexytime chapters as this makes me EXTREMELY UNCOMFORTABLE!! ok thanks ilu UwU

Summary
After choosing to stay with Toriel, Frisk, and Chara and saying goodbye to his brother, Sammy and the gang must navigate humanity on the surface with only their wits and Matthew's final gift. However, things start turning south, starting with the appearance of a shadow man. Can they trust him?

This is the sequel to Undertale: Double Trouble, which I highly suggest you read before starting on this. It has many plot points which come into effect in the story.

Summary
A collection of meta for Undertale with a particular focus on the skeleton brothers (at least for now). Unpopular thoughts and opinions are shared. Especially regarding the identity of Dr. Gaster, who I have concluded isn't Mystery Man. He's just Sans, who is not particularly special. Rather overexposed, overhyped, and overrated actually (both as Sans and as Dr. Gaster). Beware of salt and snark!
The first chapter is a table of contents and something of an introduction.

Summary
Long ago, humans sealed monsters away with a magic spell... Legends said that no one who climbed their mountain ever returned. Many years later...
One human does. And, it seemed, with all of monsterkind behind the child's small steps.
Yet, not all monsters have left the Underground. When a ninth fallen child falls onto Flowey's carefully tended bed of flowers, Flowey must decide if he will help her escape when he himself can not. Or, if he will let the last friend he could ever have leave...
Meanwhile, Ninth Child may have more to do than escape the Underground... A darkness lingers... something she has tried to escape haunts her, something stronger than any human or any monster threatens monsterkind and humanity.
The Ninth Child may be humanity's only hope at redemption, and monster's only hope for true freedom from the past that haunts them all.
--
A sequel to the events of Undertale. Frisk has, just like Flowey, exhausted all that could be done in the Underground. Curiosity lead to the ultimate evil, even worse than anything Flowey had ever committed... But with regret, Frisk attempts to reset and free all monsters. Still, something dark follows, intent on destroying everything.. -

Summary
Frisk gets a request from an old friend of theirs, one day. None of them know where that request will take them - or, to be more precise, when. But that's the deal with good intentions; sometimes the only thing they fit for is paving the road, and you don't want to follow that particular road for too long.

Summary
Even if the planet exploded or if they were hit dead on by a nuclear bomb, they would survive, though their body would be a pile of ash. They’d be pulled back together, reformed piece by piece, each cell working fast and hard to recreate each system, one after another. Thinking of the pros and cons of immortality, especially this specific, impervious kind of immortality, you’d be hard pressed not to choose it. But really, think about the cons.
Would you be the only person immortal? What about your friends? Would they die, growing old to eventually crumble into dust? What about your family? Are they immortal too?
See, when you wish for immortality from a genie, you should really kind of think about these things. It’s a bit like making a deal or a contract with someone. Only thing is, in your case, it’s with a demon from the fifth circle desperately in need of something to snack on, and your soul is the only thing that seems to be around his tastes.
Yeah. You haggled with a demon. What about it?
