First things first, I wanted to do an Undertale run, with a new SOUL and, well, in a different universe (I'm going to use a different version of the Storyshift AU). The SOUL of Loyalty would be Indigo as color.

Nightmare

All I remember was that I went to bed rather early that evening...

I surprised even my mom with this rather odd bedtime, but frankly, I was tired from the first day at school, which went okay. I often dreamt of magical places, out of reach, leaving my imagination fly - and not once my mum caught me zoning out when I had an idea in my head. "Samuel, you have to stop daydreaming all the time! I know you're just a kid, but you're going to school, your teachers will grade you, and if you fail I won't have any money to place you back in school. I barely managed to gather the necessary dollars to place you here, so please, try to have good grades and behave yourself", she kept telling me whenever I did that.

Instead of a beautiful dream, my mind seemed to have wandered into the wrong place at the wrong time. It felt so real...

[Dream Plane, in Storyshift]

I saw myself holding a knife, swinging it at beasts showing in my way, feeling oddly pleased with doing this...until I reached what seemed to be a rather large hall, basked in a brilliant light. At the end of it, somebody, or something, seemed to have waited for me to arrive, because that person's voice echoed within...

- Howdy. You've been taking a long time to arrive here, so...I had some time to think on these questions. ARE YOU SATISFIED WITH WHAT YOU HAVE DONE? DO YOU THINK THERE'S ANY CHANCE YOU MIGHT BECOME A GOOD PERSON?

- And why...should i...even care? I could hear myself, but not quite myself, saying to the person.

- Listen. I have a real dispute to settle with you...and I'll make sure you won't get to Papyrus. You've killed Sans, Chara, Asgore...when are you going to stop? This game has gone too far, and I. DON'T. FORGIVE. DIRTY. SISTER. KILLERS. . .

- Well...i am...ready to fight...you...comedian.

- I had hoped you will give up now, but I was wrong, I could note the sadness in that person's voice, and I saw the sillhouette drawing nearer. I wish we met in different circumstances...FRIEND, I could hear him utter as powerful lightning strikes were aiming at the whole space I was in.

I felt something rising in my veins, something similar to DETERMINATION, but it was so evil, so adamant on killing whoever I was facing now. There were times when I felt something different inside myself - as if there was a glimpse of good - fighting for whatever light was still existent in here. Swinging the knife, I tried so hard to kill the one in front of me: a goat-like monster wearing a blue jacket and black pants. He had white fur and the sclera of his eyes was pitch black, which intimidated his enemies, but for some odd reason I didn't feel scared about his demeanour, and he could see that too, as he placed a wicked smile across his muzzle.

- Do you really think I will take every swing in tow? Whatever is left of monsterkind relies on me to defend it from YOU.

- And...how long...do you...think...you can...last? I heard again that voice, and I saw again how I lashed at the goat monster.

- As long as Toriel manages to lead everyone to safety...and Papyrus will be able to absorb the six human SOULS, the monster said.

- What if...i wanna...stop that...he he he...HAHAHAHAHA! my...determination...is greater...i need no love compared to my LOVE...

- Golly, you look like you really want to keep going. But like I said, I won't let you get past. It is time you saw my real power, the goat monster smiled as he extended one of his paws to me, enveloping me in a star-like bubble. The stars are my witnesses you'll feel your every kill crawling back on your spine.

Indeed, I was feeling like I was carrying a lot of burdens on my mind and soul, and wincing, my voice or rather whoever's voice was that emitting from my body, rasped slowly, along with evil cackles along the way...

- This...is so...*cackles*...pathetic. You know...it doesn't last...too long...*cackle*, you can't really... kill me.

- I studied for a long time...those anomalies in our timeline. Frisk promised to me they will never RESET, but somehow, whenever we reach the end, we're always brought back here, in the Underground. SO TELL ME, FRIEND, WHY DID YOU LIE TO ME? I heard him roar as he manifested a huge goat skeletal head which emitted a powerful vortex, threatening to absorb the whole room...and I couldn't resist much longer. I remember only that I heard something before I blacked out, something like "drop dead and gone now, you fake friend!"

[Reality]

It was close to sunrise when I woke up, my heart beating so fast it threatened to leave my chest. I looked slowly around, almost wanting to reassure myself of the surroundings - the blue ceiling, my night lamp, the rather large wooden wardrobe, my computer...I stared for five full minutes at the blue ceiling, trying to calm down from the rather scary place I've seen last night. Knocking softly, my mom entered the room and noticed the rather panicky state I was in:

- Hey, Samuel, are you okay?

- Yeah, I replied. I just had a bad dream.

- Have you turned on the lamp last night?

- N-no, I admitted sheepishly, I don't want to be afraid of the dark anymore.

- You're still young, Samuel, my mom said gently. You'll grow it out, eventually. Now, do you want to have some breakfast?

- Yeah, I said, but then my expression shifted to panic.

- It's Saturday, you silly, she gently noogied me. School will start back on Monday.

- Yeah..., I trailed off.

I was half happy about going to school, really, but then again school taught me a lot of things. I even heard about the legend of Mount Ebott, which is just beyond the city, deep within the Serawall Forest...A legend that said humans won the war against monsters, and monsters were sealed within the mountain for centuries - most of us thought it wasn't right, but the teachers told us we have to fear the monsters. I was inclined to believe they were right, after this bad dream...

BUT THEN EVERYTHING WAS ABOUT TO CHANGE.
