The Lost Files

by METAmahn

The fated journey through the Underground is at a close. But with the breaking of the Barrier, comes a new story. Delve into the rabbit hole that was the man named Gaster, through his notebook and into his mind. See from his eyes how the monster kingdom achieved its golden age, and then came crashing down like a house of cards. (Hope Project: Book Two.)

1. Prelude

-Frisk-

I creaked open the door when the mailman rang the bell. It was a paper-sized FedEx package.

"What is it?" Chara yawned. She woke up at eight. On the other hand, I woke up at seven, helped mom cook our breakfasts, and was already chugging away at page 50 of the huge packet the US Government called Ambassador 101: Your Crash Course to Diplomacy when the mail came.

It was addressed from Sans. I brought it to the kitchen table, where Chara enjoyed still-warm breakfast sausage (thank fire magic and heat retention wards) while I took a knife and opened it up.

On top was a note from Sans, devoid of his usual goofy and jokester manner. It read, "KID-I managed to crack open the seals on Gaster's notebook. Give it a read."

"What is it?" Chara asked, her mouth full of sausage and scrambled eggs.

I carefully examined the rest of the contents. It was the old notebook we found, all right, but now with strange, alien lettering across it. Somehow, I knew it to mean-

"Entry and study." I said.

"Huh? What is that even mean?" Chara asked.

"I have no idea. I think I'll take a break from studying US Government materials to read this, though." I replied. I took the binder upstairs. Asgore was already working away in his office, talking with some of the local officials on a group call to get the entirety of Mount Ebott and a little distance around it as space for a monster city. And judging by the sounds from the bathroom, it sounded like Asriel was just getting around to drying himself off. Oh, how painful it must be to be a furry boss monster in the morning.

I carefully opened the binder. The spine crackled, like it wasn't opened for centuries.

"Entry Number: null."

If you are reading this, I am dead.

If you are reading this, my task is also complete.

Confusing? I hope not. In the case that you are confused, allow me to explain myself.

My name is Gaster. And I believe I know you, whoever that is reading. But old habits die hard, I suppose. I am getting too far ahead of myself.

I am the first royal scientist. And I was tasked with breaking the barrier, through whatever means necessary. I am the most knowledgeable monster on the subject of souls. The Dreemurr family barely scratches the eggshell, no matter how bright the two children are. That girl is quite something, though…

But Sans and Papyrus? They're hardly a tenth, combined. Even Alphys-Alphys-that one who supposedly continued my research-she doesn't know half of what I know.

Still here? Good.

Welcome to my personal abyss. I sincerely hope it does not gaze back.
