Weeks passed in the concentration camp. Monsters, all the monsters left alive in the world were brought to the camp.

Well... no. Not all of them. I have no doubt that a generous number of them were killed in transport.

When the last monster had been brought in, the camp population totaled a little under eleven thousand. And then we stayed there for weeks, as the humans prepared our eternal prison.

I made many escape attempts, of course. None were successful, but I tried anyway. No one ever helped me. I was always on my own, always fighting for the whole of monsterkind by myself.

Eventually, the humans finished their work. The entire remainder of monsterkind was escorted up the mountain, and into a cave. They planned to seal us into the caves under the mountain, creating the Barrier.

I made a final desperate attempt at escape. It was foiled quickly. I was shoved back with the masses of monsters, jostling to get away from the humans.

But I didn't follow them. I stayed, as close as I could to the mouth of the cave.

I didn't see the sky, not how blue it was. I didn't see the sun, or feel it's warmth. I didn't see the fields spread out beneath the mountain, the beautiful country. All I saw were the humans, working to take these things from us.

The Barrier was made with immensely powerful Magic. It required the strength of the Magic of seven human Souls. And the runes for it couldn't merely be written, they had to be spoken by the seven human Magic-wielders who were making it. So yes, they were practically spellcasting.

And I stood there, as far as the human guards would allow me, staring at the spellcasters.

I hated them all, of course, but one in particular caught my eye, one attracted the gaze of the fire in my Soul more than the rest.

There had to be seven humans, one of each of the core Soul traits for the proper Magic. It was the green Soul, "kindness" who caught my attention. She wore extravagant green robes, silk, probably, that shimmered in the twilight. I hated her more than the rest for two reasons.

First was her hypocrisy. Green is supposed to be kindness, yet here she was, dooming eleven thousand monsters, dooming the last of their species to die in a dark pit. That was hardly an act of kindness.

But more than that, I hated her for the greenness of her robes. The same shining emerald of Firhaur'a scales. No human, no filthy murdering human deserves to set eyes on such a beautiful color, let alone clothe themselves in it. No beast so Soulless is allowed to dishonor my brother like this.

I SHOULD HAVE R I P P E D H E R A P A R T W I T H M Y O W N H A N D S . I S H O U L D H A V E W A T E R E D T H E G R O U N D W I T H H E R B L O O D . S H E D O E S N O T D E S E R V E T H E L I F E S H E D E N I E D M Y B R O T H E R .

I should have killed her. I wish I did.

But I didn't. I only just stared, putting all my hatred into my gaze.

It's with no small amount of satisfaction that I say she caught my gaze, and she faltered. Her voice tapered off, separating from the rest of the six who were casting the runes for the Barrier.

She looked scared. Horrified. Terrified.

She looked like she knew what I wanted. Like she knew my desire to wet my hands with her blood. Like she knew that if I got the chance, I would take it, and there would be nothing she could do to stop it.

For a seemingly infinite moment, I held her gaze. She couldn't look away, I know. She may have wanted to, but I wouldn't let her.

This, this was my final attack, my final vengeance against the humans.

And then one of the other seven nudged her, and she managed to tear herself away.

And then it began to construct itself. The glowing, pulsing wall that cut monsters out from the world.

Oh, how I loathe that Barrier! If not for it, I would have never attempted the experiment that led to my erasure from existence!

... The humans killed my brother. The humans created the Barrier. The humans separated me from my sons.

I

Hate

Humans.

I cannot emphasize that enough.

...

... But I digress. On with the story.

So we were sealed in the caves, which Asgore would name the Underground. He... he was not the best with names.

I wanted to stay by the Barrier. I wanted to stay there, to find a way to break it. To get my vengeance on the humans.

But Asgore argued. He said the people were scared, they wanted to get away from the humans. The Barrier was too close to them for the monsters' comfort, especially since anything could enter the Barrier.

They wanted to move deeper into the caves, and Asgore told me that the people needed their Royal Scientist as much as their king. He said that in the war, I had been a beacon of hope. The fire that lit the lighthouse. And if I refused to go with the king... well...

It would only unsettle the already shaken monsters.

With Asgore, Toriel, Dagiel, and Gerson all arguing to me, I was persuaded to accompany the monsters deeper into the mountain.

We passed through the center of the mountain, the molten, inactive core of the volcano. Eventually, in the far, far future, with Sans' help I would build the Central Optimal Resourced Energy unit- the CORE, there.

But, considering Asgore's ability with names... the fiery location was dubbed Hotland.

Beyond Hotland was a series of beautiful caverns, covered in shining crystals reminiscent of stars. The only problem with the place was how wet it was, how muddy. Water practically flowed down the cave walls.

This, of course, became Waterfall.

Beyond that was a massive cavern, complete with an evergreen forest and its own small atmosphere. The place was covered in snow. We got holed up in a few caverns for four days as a result of a snowstorm, which led to Asgore's naming of the place as Snowed-In, which was eventually shortened to Snowdin.

And finally, beyond that, we came to the series of caverns that were far enough from the Barrier for the monsters to be comfortable.

This place, although at the time it was little more than caves, Asgore named Home.

Originally the whole bit with the Kindness Soul wasn't going to be here. It was inspired by the short story by @Flightmare_rider titled "Green Witch." It's a fan-work for my universe, and it's totally awesome, and if you haven't read it yet, you totally should!

Anyway, thanks for reading, and I hope you enjoyed it! Comments and votes are my Favorite Things, and every notification I get makes my day!
