Summary
Monsters came out of the mountain last year. An unknown number societies filled with creatures small enough to be held with one or two hands. Without their Core, their Souls need to gain ‘magic’ from Human Souls caring for them. So of course, shops popped up all over the place advertising different ‘varieties’ of ‘Bitties’ for Humans to ‘adopt’.
I’ve seen plenty of these poor little creatures up close and I’m telling you, these are tiny people who deserve more than pet status. Not to mention the fighting rings. There’s intelligence in their eyes that I don’t even see in half the Human people I encounter. Not that I’m particularly interested in encountering people. My street cat Emily and I prefer staying at home, making just enough money off of my video game streaming to stay afloat.
Emily is an odd cat. She came into my life freshly pregnant and demanding to be my cat. Her cool as fuck skeletal pattern gave me the idea to keep my identity online a secret by slapping on skeletal face paint. The viewers love it.
Sadly, Emily gave birth just a few nights ago, to a litter of stillborns. She’s been beyond miserable. She goes out every night now, I’m really worried about her.

Summary
Frisk completed a neutral run, and made it back to the surface like they planned. But in doing so, they left behind a path of irreversible damage. In this neutral run, Toriel had returned to rule over the monsters. But the rest of monster kind was against the idea of making peace with humanity, so Undyne exiled her back into the ruins and took over as the new Queen of the underground.
Toriel, disappointed in her own kind, retreated without a fight. She was surprised to hear from her door pal later that day that he wanted to come stay with here. “Don’t you have to take care of your brother?” She asked, only to be met with eerie silence for a moment before he responded with “He doesn’t need me anymore…” Of course, that worried her. But she didn’t have the heart to deny entry to the one and only monster left that still believed in her views.
It’ll take courage, faith, and love to make it through these difficult times. But there’s nothing that the Ex Queen of monsters and her punny little jester can’t handle as long as they have each other.

Summary
Mettaton and Burgerpants’ lives grow increasingly more complicated after a moment of snooping crosses a line. Thankfully, HR won’t be getting involved! Mettaton’s brand is a monster-run operation, after all.
Set in the post-Pacifist surface route, this story follows the Underground’s former superstar—now a rising celebrity among humans—and his increasingly inappropriate working relationship with his employee. Public scrutiny, political tension, and poor decisions ensue. Burgerpants is not cisgender. Obviously MTT isn't either.
This is intended to be a longer, character-driven work with shifting perspectives. Side stories focusing on other characters may branch off into standalone one-shots, all of which will be posted to this account.

Summary
It’s fun being dead.
Or undead, rather, as your sister likes to correct you. Your dear sister is the kind of person who took her dark arts very seriously. Or, her necromancy, rather. You’ll be the first to admit, you don’t know a lot about her school of magic. She doesn’t know much about yours either, but it’s always enjoyable to discuss magical theory with her. She says it’s not her specialty, but she tends to under credit herself.
