Summary
With the ascension of monsters, there hasn't been a boring day since. Living in a town close to the mountain range had its perks, and things certainly changed when the neighbourhood I lived in starts getting new residents.
The only problem now is finding a better job.
Luckily, a skeleton appears and tells me about a restaurant I can work at. I accept.
And I soon run into a whole bunch of other skeletons that all seem to like me.
Romantically, and I'm afraid of what will happen. -

Summary
Finding yourself in a whole different multiverse wasn't exactly how you were planning your week to go, but knowing you, it was bound to happen at some point.
But hey! It's not all that bad.. well except for Dreamtale being in utter chaos, not having the squad with you, and being 'kidnapped' a couple times. But then again, this multiverse was already proving to be much better than your previous one. Or at least, there is more opportunities here. And come on, how could you miss the chance to see this many stars?!
Now you just needed to figure out how to get the squad here, hopefully without the stupid chicken.
Nightmare has a bad feeling, your Nightmare. You'll just have to make sure he doesn't go insane with worry.

Summary
He knew that you wanted him, and that your seemingly innocent teasing was an attempt to take charge, to take his control away from him.
His sharp gaze told you that he wasn't going to let that happen so easily.

Summary
Humans are afraid of the unknown. The solution to this problem? Welllll uhh... it's obviously to shove the problem in area 51 one and then build a school the size of America's need for healthcare since copies of the problem JUST. WON'T. STOP. SPAWNING. So follow the story of the troublemakers of wing 4-B I guess..
or
I shoved a bunch of random characters in area 51 and built a massive school on top of it because why not at this point. And characters are very ooc.
(Not that much knowledge of the characters is needed)

Summary
You're an engineer who works for Ebott's best research facility in one of the labs; your lifelong dream after finding a journal on Mount Ebott when you were a kid. When you aren't in the lab being smart, you're gathering materials at the abandoned doll factory for the machine you're trying to build.
But one night, you meet a skeleton at the factory. Naturally, you lie about why you're there and say you're there to hunt ghosts. You befriend him and try to find a way to gather the materials while keeping up with that lie. But those lies catch up to you when you start to meet all the other skeletons.
Edit: As of Chapter 29, all chapters have been edited and fixed slightly!

Summary
You’ve all heard the tales of Dream and Nightmare.
Legends whispered across the multiverse—crafted and retold by countless creators.
Stories of their endless journeys through realms unknown, where hope blooms at Dream’s touch and despair follows in Nightmare’s wake.
With each world they visit, the balance of Light and Darkness shifts.
But have you ever heard about THEIR story?
Not the stories shaped by others, but the truth buried beneath it all.
The tragedy that binds them. The pain that forged them.
How the arrival of a single group shattered the fragile threads of fate—changing everything.
If not, sit back. Relax. And grab your bowl of snacks or that plate of food.
Because what you’re about to hear is the story of the Dreamtale Twins.
And it begins long before the multiverse even knew their names.

Summary
Luz struggled to wrap her head around all these revelations, taking a moment to let it all click into place in her head. The Collector just hooked their reality onto a multiverse. Doing so was a collaborative effort with the Grim Reaper from said multiverse. They met while he was reaping souls from a warzone. He works for many gods and deities in what amounts to a divine version of Community or The Office. Papa Titan used to be in there, but now the Collector is.
‘So every time I sent a letter to Frisk, I was mailing to another universe,’ she rationalized out loud. ‘Which would basically be no different than sending letters to and from the Boiling Isles. And the Titan was more or less the Demon Realm’s god but now…okay, fanfic logic, I can make sense of this. Neat!’The world of The Owl House is the latest addition to the Nexus, a amalgamated universe comprised of multiple worlds patched together. The protagonists of the world quickly befriend each other and help each other and their friends navigate this new situation whilst also staying a few steps ahead of Alastor's mysterious mission and Boscha's need for petty vengeance.

Summary
“YOU LOST IT?!”. Were the three words that echoed through the throne room, shaking the large ebony pillars that lined the walls. “WHAT DO YOU MEAN YOU LOST IT?!” “Well if Cross ha-”. “I don't care who’s fault it was, this was the easiest mission I have EVER tasked you three with!” A heavy grunt escapes Nightmare as he sinks into his seat. Pinching his nasal ridge. His tentacles dripped and swayed furiously. “Cross, seeing as you were the one leading this mission, do you care to explain what happened?”
Cross steps forward and bows down before the big throne. “Well, uhm, you see…”
