Summary
In the smoky underground clubs of the 1920s, three gifted musicians-Bree Reyes, a gentle singer filled with care and love for others; Macy Clark, a charming easygoing pianist; and Davidson Smith; a hot-headed cellist who always finds himself into some sort of trouble-find themselves swept into a world far more dangerous and exciting than they've ever imagined.
Their music catches the attention of duo benefactors- a well-mannered woman and her business partner, a sharply dressed skeletal figure dressed in blacks and reds.
The trio are given an offer of fame, fortune, and protection-but of course, there's a price to everything.As their careers skyrocket, so do the stakes. Bree becomes entangled in a forbidden romance while Davidson wrestles with addiction, ambition, and a chilling realization that not everything is as it seems. Macy, like always, is stuck in the middle.
Torn between love, loyalty, and survival, the trio must find themselves in this new environment, make their own paths through this monstrous city, and compose their own fate before the final curtain falls.

Pacifism Cannot Break Barriers by Sage_Against_the_Machine
Fandoms: Undertale (Video Game), Deltarune (Video Game)
31 Jul 2025
Tags
Summary
“How do you hold a psychopath?”
“…with both hands. Because someone did that for me when I thought I was the monster.”
Frisk has done it—gotten to the end, gathered the souls, spared everyone… Yet, the barrier stands strong. Madness ensues when humans start falling down to the Underground again… and the true enemy manifests in the form of a glitch between worlds.
Chara is back. Papyrus has a gay awakening. You take the role of the player. Asriel reconnects with his feelings. Sans reconnects, in general.
(Kind of my thoughts on all three endings mixed together. A little AU-y, especially with Chara's story. May not be 100% accurate to the series, some bits may be cringe taken seriously, others may be out of character, but that's fine. Headcanon: Paps is 18-24, Sans is 26-30.)

Summary
Rather than the selectively mute child who let things flow without any thought of disturbing the pre-established script, it was the mafia boss (in training) who descended to the UNDERGROUND instead.
And Sawada Tsunayoshi never like it when someone tried to chain his will down like a mere puppet.

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
Hello!
In honor of Underverse 0.8 part 1 coming out and Jakei’s year and a half hiatus, I am going to (try to) do this thing I will be calling “Weekly Underverse” where I update weekly with some sort of Underverse related content.
It’s not going to be anything big. Some weeks it will be a 3,000 word Cross fic, maybe a digital drawing I worked on for 5 hours. Other weeks might be as small as a snippet of a poem that was inspired by an Underverse thing, or a little doodle I did in my notes packet. It may even be recycled content I have posted outside of this project.
But whatever it is, I will try to update it weekly until the hiatus is over.
Weekly Underverse starts today, November 20, 2024. Updates will (try to) be every Wednesday.
Underverse belongs to: Jael Peñaloza
Little note: I am nowhere near an Underverse expert, so most things might be fanon, most things might be Cross focused, but maybe I’ll do some learning and write with the other characters. Maybe I’ll give fun facts one week. We’ve got about 78 chances so… we’ll see where this goes!

Summary
Across the full Multiverse, various ripples were made by some subsections connecting to each other via mysterious multiversal group chats.
Of course, while many see great things caused by those ripples, not everything they do is a good thing.
One subsection has received various severe damages to its stability due to those ripples, and so, to try and ensure the events and adventures of the worlds in its subsection happen properly, four entities have come together to create a group chat of their own. They have placed a great hero, known for being able to protect children from even the most bizzare dangers, as its admin.
Join Hiro the Yoshi as he tried to keep those kids alive so they can reach the end of their journeys safely.
But first, he has to get them to get along with each other.
What were those entities thinking...?

Summary
Monsters are free, and Frisk is safe and sound at home.
It feels like fairy tales are real, though a rough break-up after eight years of marriage quickly sobers that thinking.
With the break-up follows a proposal straight out of a steamy novel: share a room with a man you've just met, while you get back on your feet and work on the process of finding a new place to move into.
Turns out, the guy who smells like grease and beer from how often he visits Grillby's is a lot less romantic than you would think.
And it's precisely living together what gets you to know all the icky things about him.
Until you end up falling for him with each nice little thing he does, and suddenly...
It feels like all those icky things start to matter less and less.
More so, when things take a sharp turn and you're in the middle of a gang fight, helping him however you can despite not knowing what you're signing up for.
Overlooking details like bloody clothing, chipped teeth, and reports of missing people on the telly make seeing him drinking straight from the milk carton a much more tolerable offense.

For Frisk, it's a return to some uncomfortable realities.

Except, 'moving on' was not so simple. Emerging from the Underground had put them in a worldwide spotlight.

Summary
After countless resets and endless repetition.. something has changed. The timeline has began shifting, changing its path for the first time in a long time. A new path Flowey hasn't seen before.
Well, it might take Clover longer to reach Asgore but Flowey has all the time in the world after all. And seeing something new finally happen has piqued his curiosity. Drawn in by the unfamiliar, Flowey watches with morbid fascination as Clover is not able to give up his soul this time. Encounters shift, monsters react differently, and the world itself begins to remember things it was never meant to.
Events shuffle. Characters act out of turn. Rooms appear where there were none. And for the first time in countless resets, Flowey doesn't know what comes next. Clover's fate is uncertain. Though Flowey knows he will get those human souls, no matter what.
