A Tale of Stars And Time by Pikapuff30
Fandoms: Undertale (Video Game), Deltarune (Video Game), In Stars And Time (Video Game)

Summary
A Tale of Stars And Time is a crossover AU/AT that combines both Undertale and In Stars and Time. Originally inspired by a few memes/fanworks of Siffrin in Undertale, this concept does exactly that – take the characters from ISAT and shove them into Undertale and see whatever the heck happens next.
The general plotline involves Siffrin going through their usual time looping shenanigans in their own world when, mysteriously, a strange grey door appears in a hallway that definitely wasn’t always there. Upon closer inspection, Siffrin and co. are suddenly thrust into the very beginning of the Underground. They are soon met by Frisk, a strange child with more to them than meets the eye. Now, the six of them will journey through the Underground, meeting familiar friends and dangerous foes, with plenty of surprises along the way.
A new play is about to begin, so get on stage, stardust~!

Summary
“How could Isabeau explain the desire that had nestled into his muscles, into his bones, into whatever ephemeral selfhood he held in his chest? It wasn’t a need like food or water. It wasn’t an arousal that could be taken care of. The closest term he could come up with was morbid curiosity.
He wanted to see Siffrin again. Truly see them.”
---
For once, full-throated acceptance of one’s inhuman nature is not the answer.

Summary
Isabeau once joked that if he ever needed to get away with murder, he would make sure to ask Odile for help.
She didn’t mind the joke, in fact she tried to play into it. She was more ruthless than the others, scarier, and it was for the best to keep that comparison humorous. To limit her terrifying side to chilly glares and threats of spicy food. It stopped the others from dwelling on it long enough to ask questions, which in turn helped her keep certain things buried in the past.
Then Siffrin knocked on her door in the middle of the night and asked her for just such assistance. Suddenly it wasn’t a joke anymore.

Summary
⋅☆⋅ The night air slaps your face, cold, shocking, but it’s not enough. Your body doesn’t cool; if anything, the contrast only makes the heat inside you flare harder, pushing sweat down your back, slick between your thighs. You rub your cheek against the nearest tree trunk without thinking, dragging skin raw just to feel the scrape of it, just to mark something. You hate the way your breath hitches, how your legs want to buckle at the stupid, instinctive relief. ⋅☆⋅

Summary
ˏˋ ✮ ˎˊ Stardust leans toward you, lips already parted, eyelid half-shuttered in that teasing way that makes your pulse hammer. Their hand cups your jaw like they’re guiding you into prayer, thumb dragging at the corner of your mouth as if measuring how far they can take you. The paper burns low between their fingers, ember threatening to drop, but you don’t care. You don’t even blink. You open, because of course you do.ˏˋ ✮ ˎˊ

Summary
Jouvente seemed like a much nicer city when Mirabelle wasn't worrying about the apocalypse.
----
It's been well over a year since the King had been defeated; since Vauguarde had been saved; and since the Saviors themselves decided to continue travelling together. Their last stop before sailing to Ka Bue? Somewhat fittingly, it was the first city that Mirabelle entered on her quest: Jouvente, the birthplace of their resident fighter.Not that you could tell from the way he was acting - sure, he had mentioned plenty of the restaurants he was excited to treat them too, or his favorite landmarks he would take them to, but Isabeau had kept conspicuously quiet about the people from his past. If he didn't want to mention meeting up with any friends or family, well, that's his choice to make. Change knows his new family had kept larger secrets.
But just because Isabeau's more than ready to leave the cities' residents behind doesn't mean that they're finished with him. And some of them are of the opinion that he's long overdue for a family reunion...
———
Isabeau’s family reunion!

Summary
It was just another nightmare.
That's what Mirabelle tries to tell herself. Tomorrow's the day they all fight the King, so whatever torments her anxiety-fueled mind brings up to haunt her are nothing more than phantom visions.
(But of course, she's wrong about that. And about a lot of other things — turns out, getting trapped in a timeloop alongside one of her closest friends makes her quest to save her country a lot more complicated.)

You Really Are Stupid, Aren't You Stardust? by Impostor

Summary
For whatever reason, the Universe just couldn't let you rest. Instead, you wake up in this BLINDING body, with this BLINDING PARTY, and you have no choice but to be called to understudy Stardust's newest performance. Watch Stardust live out his happy ending with a front row seat. How lucky.
(Or, I noticed that most post canon fanfics have a healthy amount of communication, and Loop is the perfect device to fix that.)

Summary
You aren't sure how much time passed.
For all you know, it could've been so long, the previous system had already left the radar’s map- you are obviously in deep space already. You are incredibly grateful for your ability to tell if you are under artificial gravity well, as you had not been aboard the ship before you went to sleep, and you are rather sure you are moving somewhere against your will or knowledge.
The place you are in currently is, after all, a cell.
