If I got transported into nightmare sans's body!? Featuring Me IRL

Hello darkness my old friend~

It turns out that this multiverses Fate had actually transported my physical body here and managed to corrupt it and merge my soul with nightmares soul, making me all bones and goop. How that works I have no idea, but it's the undertale aus. And sadly I don't know as much as I would like...

I've decided to call Nightmare Night for short, and he's been helping me learn how to use my magic. Apparently he has his own Au where he has a castle, and he told me how to make a portal to the castle!

I gotta say. The castle is beautiful.

"Whoa.... This place is amazing!" I said, starstruck.

"Thanks, I guess.." I looked over at Night to see him blushing at the compliment. I don't think he gets those often.... "I- uhm- designed it myself."

"Whoa! Really! You did an amazing job Nighty!" Night started to blush even more, his entire skull becoming a lilac color. I giggled at that, which only made his face a deeper purple.

After a few minutes, Night and I walked around the castle. The place consisted of a garden, two kitchens, a throne room, a office, a play room (Night doesn't even know why he has that), a dungeon, a meeting room, a dining room, a training room, many spare rooms and closets, and multiple bedrooms.

Dang, this place is huge-

After the tour we went to the training room, where Night helped me summon Shadow Papyruses! I only made a few though. I don't want to make too many of them, only for me to lose track of who is who....

~a few days later~

I can't get any sleep. It's too quiet in the castle.

Back in my world, I had realized that I can't sleep without signs that there is life in the room. When I was a kid I always had a sound machine in my room, playing music, and as I got older I always slept with my headphones playing music. Lately, I had put a sound machine back into my room, with the machine playing rain sounds. But now that I'm here at the castle, without any signs that there is any life here but my own, I can't get any sleep.

Suddenly, I got an idea!

If Nightmare is supposed to have his gang, and we don't have one then... "hey Night?"

I asked.

"What." He deadpanned, causing me to slightly flinch. "Did you have a gang of some sort? Or was it just you?"

"It was just me. Why?"

"Because I have an idea on how to help me sleep!

"As you know, in my world we know all about you and different Aus of yourself from many different multiverses. And in almost all of them you have a gang of sanses who all had horrible backstories and lots of trauma."

".... Are you saying you want to create a gang in our world, full of psychopaths with loads of trauma, just so you aren't by yourself and can sleep properly...?"

"We'll when you put it that way it sounds like I don't care about others... and it's not just so I can sleep. I kinda have wanted to help them out for a while, you know." I looked up at the black ceiling with a dazed look. I really need to add some color to this place.

"If I can help them, they don't have to be alone and stuck either reliving their pain or with the consequences of the humans actions... that way, none of us will be alone anymore."

I smiled slightly, only for it to falter.

"But, you're right... they may not want to come, and it is really selfish of me..."

"*sigh* no no, you make a better point than I do(surprisingly.). From what you've told me about the different Aus, most of them are either all alone in a dust filled Au, or close to death because of someone in their Aus.. I say, we go and try to save them!"

I looked at Night with a shocked look, only to return his 'enthusiasm' with a closed eyed smile. "Thank you Nighty!"

I open my eyes to see that he's smiling back."Well then, let's get going, shall we?"

He asked while floating down to the grown, holding his hand out to me. I took his hand and stood up. "Let's do this." I said, filled with DETERMINATION.
