Brothers tale

Prologue: The Three Brothers Overground

Gaster looked at the area around him in wonder. Mt. Ebott was one of the strangest biological and geologic anomalies of the world. The West half of the mountain was covered in a bountiful forest filled with flora and fauna. Brimming with life compared to the opposite East side which was almost completely void of it. Gaster was here studying the area with his two younger brothers Papyrus and Sans. He had always been interested in biology and history ever since he was a child. Of course he knew of all the legends of the cursed mountain but he knew most of it was just that, legend. No aspiring scientist would pass up such an amazing research opportunity as Mt. Ebott based off of a silly curse.

Gaster began taking notes when he heard his baby brother's loud squeaky voice shout.

"look a squirrel!"

Gaster looked over to where his baby brother Papyrus stood pointing. About 10 feet away was a fluffy brown squirrel with a fluffy and long tail trailing behind it. Sans who had been standing next to Papyrus looked down to meet his brother's eyes, smiling he said

"Don't go nuts over a squirrel kid."

Papyrus threw up his hands and ran away screaming

"NOOOO."

Sans burst into laughter over his kid brother's reaction. Gaster joined in the laughter but quickly recovered and had to call Papyrus back.

When Papyrus finally came back the three continued up the mountain. They were almost halfway to the top when Sans pointed over to something.

"What's with the vines?"

He said puzzled. Sans's inquiry brought Gaster's attention to a trail of tangled vines in front of him. Dozens of vines twisted and turned around each other spreading out after a certain point and heading down the mountain side. Gaster's eyes followed the trail up the mountain all the way up to the mouth of a cave where all the vines seemed to converge.

"Let's take a look"

Gaster said as he began following the vines up to the cave. He had never seen vines grow so far from their point of origin before.

When the three brothers came to the cave. It only seemed like the vines grew deeper and deeper into the mountain. Soon they came to a point where Gaster had to pull a flashlight out of his backpack so they could see. Eventually the cave opened up to a large dome like chamber where a large hole about 15 meters in diameter dropped down into a dark abyss. Looking up a hole similar in size opened up the ceiling letting large amounts of sunlight to flow in. All around vines zig zagged around the walls and floor then dropped even further down into the hole.

Gaster marveled at the scene around him then remembered something. Back a mile or two there was a small town named Ebott, after the mountain. The people there warned Gaster and his brothers about a curse on the mountain that made it so all humans who went there would disappear. One old man informed Gaster that the mountain contained a way into the monster world. Before Gaster had brushed it off thinking it was just a crazy old man's ramblings, but now it seemed... He shook off that thought, the hole had to be just some sort of ancient lava vent that had been filled with rain water when the Lava disappeared. That would explain why the vines seemed to collect there.

Besides no one has seen a Monsters for at least a hundred years most likely someone just made them up to scare people. That was the most logical explanation anyway. Gaster was about to call out to his brothers so they can leave when he noticed Papyrus had gotten dangerously close to the edge looking down into the hole before him but before Gaster could say anything. Papyrus shrieked when a vine suddenly ripped out from under him sending him to the void, both Sans and Gaster rushed after Papyrus only to trip on the many vines and fall down with him.

Soon the three brothers were sent into a free fall into darkness. For what seemed like forever Gaster saw nothing to indicate where the ground was all he could hear was his own screams mixed with that of his brothers. He expected that at any moment the ground would come up to greet them and that would be the end of them but it never came. Instead a bright light from below engulfed the three boys and then nothing.

Gaster slowly opened his eyes. He saw a light shining down from above. He sat up. Looking around he saw his two brothers still unconscious than he remembered. They had all fallen thousands of feet but, how were they still alive? Let alone uninjured. After taking a quick survey of the area. He noticed that the bright light shining from above was from a hole in the ceiling. The rest of the room was so dark that Gaster couldn't see the walls then he stood up and noticed that below him and his brothers was a large patch of flowers and upon further observation he found out they were Butter cups.

It seemed that somehow butter cup seeds had fallen down and had grown in the one spot that was lit with sunlight. Gaster decided to leave his brothers there for now and find an exit. It didn't take long though considering there was only one way out. It was marked by a large stone arch. Gaster couldn't believe that a thing like this would be down so deep underground. Examining it he gussed that it was at least 100 years old if not older. Despite this the ancient structure was still in good shape.

He took a quick look back at his sleeping siblings before stepping though the archway. On the other side of the arch there was another room similar to the first, with light floating down from a small hole in the ceiling and darkness covered the walls from view. Another small patch of grass sat in the center of the light. Gaster turned to leave and get his brothers when he suddenly heard a voice shout.

"What are you doing here idiot!"

Gaster whipped around to see a tall goat girl. She looked like a teenager but stood tapping her foot like a mother dealing with a frustrating child. Gaster began to explain

"Me and My brothers fell down and.."

He paused

"What are you?"

he asked.

"A monster of course."

The girl said matter-of-factly.

"You must be a human and before you start calling me Miss. Monster my name's Toriel."

She outstretched her hand waiting for Gaster to take it, he took it and simply responded with.

"Gaster"

he didn't know if this monster could be trusted or if this thing was just a hallucination but he decided to go with it.

"So can you tell me where I am?"

Gaster asked politely.

"The Underground. Well at least the ruins of it."

Toriel responded

"Ruins?"

Gaster asked.

"A long time ago humans attacked the monsters and sealed us underground. This is the ruins of the once great monster city they sealed away with them."

Toriel seemed to enjoy explaining the history to Gaster.

"The ruins were abandoned when we found an opening in the caves that lead straight to the barrier. Though with the population growing so quickly we might need to move some people here."

Her mood seemed to darken when mentioning the idea of moving people here. Gaster thought about the barrier, it sounded familiar but before he could press her more on the subject. Toriel suddenly gasped and Gaster turned around to see Papyrus and Sans standing behind the doorway. It seems that the two had woken up while Gaster land Toriel had been talking.

Toriel squealed and ran over to Papyrus picking him up and swinging him around. She then pulled him in close for a hug

"You're so cute and huggable."

Toriel cooed squeezing Papyrus who responded with shouting.

"STRANGER DANGER!"

After some more introductions Toriel offered to be their guide through the ruins. She said that alone the underground could be dangerous for a human and they could get lost. But she seemed more concerned about Papyrus's safety than any of the other brothers but Gaster was glad to have someone who would know something about the strange world the brothers had fallen in. Gaster didn't know what dangers this world will hold but whatever it threw at him he knew he would take it on with full force. This thought filled him with DETERMINATION.
