Summary
[[DON'T READ THIS. There's nothing here right now!!!]]
It was supposed to be a simple mining expedition: The quantum navigator picks a planet, drops your crew, and you assemble at your mobile base, then work together to survey the planet in hunt for some elusive and evolutionary material. Easy.
A little less easy when majority of your crew dies for mysterious reasons, and the people who are left standing is you (a botanist), and a scientist named Sans. How the hell are you supposed to operate this mission without anyone to fix the damn base if it breaks???

Summary
You walked into the forest, knowing once nighttime fell, monsters would come out of their burrows, and you'd be killed.
Somehow, you ended up becoming the pet of a skeleton-spider-centaur instead. Black seemed to believe you were just an animal, rather than a person. His brother on the other hand... You couldn't be sure, but he might be onto you.
(i've been asked to add a disclaimer that this is not a retelling of horrortale in a swapfell setting, so here you go. the monsters live underground, but with access to the surface at night, human eating won't be a big topic in the story)

Summary
(Vaporswap Official Fanfic! - Original Horrorswap Au)
*The air was so thick, it was like liquid in your lungs.*
When you'd gone to that abandoned power plant with your friends, it had at least sounded like a *decent* idea. Who could've known it would lead to such a wonderful, *horrible* world of discovery?
"If all you can breathe in is the horrors of the world, wouldn't you rather stop?"
"But how then, could I breathe with you?"
(This is my first fic, wish me luck!) - Also I just realized people might find this on HERE and not from Tumblr, so for art-work of the boys, the underground, and whatever else I come up with, plus more writing stuff, or asking me questions, here's the Vaporswap Masterpost: Link
