Summary
Nicholas Holiday is despondent. He has sat in bed for hours and hours, on the verge of rotting away. This is typical of him, but it doesn't make his mother any more approving of it. But his sister, December, imagines that he doesn't just act like this out of laziness or ennui. She's going to figure out what's hurting him.
Noelle Holiday comes out, experiences loss, gets really fucked up generally, transitions, gets abused, lives through Weird Route, and maybe has the kind of happy ending she actually deserves?

Summary
Kris agrees that whatever happens in the plan, they'd get what they want at the end of Carol's deal, to get their old life back. They were prepared to be possessed and had everything set up perfectly, however, what they weren't prepared for was that the "Demon" possessing them was actually someone out of their town, three cities over, and three decades past, beneath 7 feet of dirt. But it shouldn't have bothered them. After all, they said they would do anything for it... right...?

Summary
Telila had never really did anything remarkable as a scientist and she knew it, she wanted to be seen as a one and not just the coworker of alphys and gaster. She had been trying to be more useful to society in the underground by fixing more stuff, discovering new stuff or even making new things. But the underground had a bigger concern, the barrier. She noticed that her efforts were less and less acknowledged, that her friend Gaster acted distant and that the king seemed more distracted... Then a question appeared in her head, it lingered and made it almost impossible for Telila to think about something else: could she make a nonhuman soul strong enough to break the barrier? After a few tests and studies she came to the conclusion that she could, by taking any kind of fragment of a soul and fuze it with another weaker soul and in this case an animal soul's, it would make it strong enough to count as another human soul and break the barrier. she didn't want to take the soul of another monster to strengthen the weaker soul and she didn't want to take only hers either, it could harm or even worse, shatter the soul of the monster. But with a little help from one of the human soul she wouldn't even have to sacrifice her soul.

Summary
Adults lied. It was what they did.
They said they would take care of you, but they didn’t. They said they would be there, but then they died. Sans had gotten used to it.
But Papyrus shouldn't have to.
And if Sans had to take matters into his own hands in order to make sure he kept his promise to his little brother? Then so be it. It was Sans and Papyrus against the world, and some gangly skeleton with gentle sockets and a weird font wasn’t going to be the one to change that.
—
“Sans, wait—! Please, let’s just talk for a moment—!”
“no way, you creep! leave me alone!”
“Excuse me?! I’m not a creep! You have many people very worried about you—”
“nah, you’re not excused. gimme 500 g and then i’ll consider it.”

Summary
Ever since Gaster came into your life, things have been nothing short of dramatic; You'd fought with his younger brother, Sans, discovered magic and became a mage, freed Gaster from the void and destroyed half the Underground in the process as well as reunited Chara and Asriel with their family.
Maybe a beach vacation with your new friends is just what you need to unwind from the stress of your life.
Of course, these are monsters you’re dealing with, since when has anything involving them gone according to plan?

Summary
Killer has heard of a pond that turns people into mermaids at midnight during a full moon. After setting out to prove it wrong, things go awry.
Note: The first 3-4 chapters or so were written a year ago, but they have such a unique soul to them that I'm not rewriting.
Updates semi-daily until August, meaning I'm trying to write one chapter every day and may or may not succeed at this task. -

Summary
You first see it when you’re half-distracted, slamming numbing palms into walls to see just one more secret, one more passage. You open the first door you see and it’s there, greyed out and hollow, not so much standing as just existing in the center of the room. Its face looks cracked, forever stuck in unmoving pieces, a stillness so unnatural that it sends a bolt of fear through your chest. You freeze. It doesn’t react.

Summary
Unwilling to kill to claim a soul—or to strike down the monster king to escape—Frisk chooses to stay underground. The monsters crown her their princess, and she grows up among them, a symbol of hope and peace.
But shadows from the past refuse to stay buried.
When the fragile peace begins to crack, Frisk must face what she's tried to forget. Alongside her childhood friend, Sans, she sets out to protect the only home she's ever known—and the people she loves—from a threat that spans timelines.

Summary
There are infinite opportunities in this world. Infinite opportunities for dreams. Infinite opportunities for hopes. Infinite opportunities for regrets... for loss.
There are some memories you would rather just forget...
The old royal scientist knew that better than anyone.
BRIGHT, BRIGHTER, YET BRIGHTER. SO YOU STILL SHINE ON, EVEN AFTER EVERYTHING YOU ENDURED. EVEN THROUGH THE COLDEST NIGHT.
But a story doesn't have to end the same way.
EXCELLENT. TRULY, EXCELLENT. LET US BEGIN THE CREATION OF OUR NEW FUTURE.
Sometimes... a game can have a secret ending.
(A Deltarune novelization that takes some unexpected turns from canon. Based on some theories, and a little bit of imagination, even the unknown can make itself known.)
(Custom Art and beta'd by Primordial_Rebel_Jester. Story by FoundUser.)
