I remember everything on that day. My vision fading as I died. The rush of power as my soul fused with Asriel's. The sensation of passing through the barrier. The warm light of the sun.

Pity the humans had to shatter the beauty with their screams.

"Get out of here monster!" The only monsters here are you.

"It killed that child, now it's coming for us!" You're damn right we are.

Arrows and rocks rained down on us as the people in my village scrambled away in fear. Funny thing for the second deadliest species in the world to do if you asked me. But we weren't there for that.

'Azzy, remember that we need seven souls to break the barrier! In fact, if you don't want to fight then I've got at least six that might not give us souls but still deserve to die.'

No response. The pain was starting to ramp up and I vaguely recognized the sound of a rifle being loaded. Chaos was descending even quicker than our HP. Desperation kicked in.

'AZZY, WE HAVE TO FIGHT BACK! IF WE DON'T WE'RE GOING TO DIE!' then I finally started listening to him.

'Chara, please, anything but this! We can find something else to break the barrier, we can figure out another way, but please, not this!'

I stopped. What was I thinking, dragging Azzy into this? Even since the beginning, I had assumed what he wanted. He didn't want revenge. He didn't want humanity to die. That was what I wanted.

So now, when it was far too late, I let him do what he wanted.

I watched as he gently shifted my corpse in his arms, gave the humans a sad smile and headed back to the mountain, with dust drifting off us like snow. We only managed to walk to a nearby river before we collapsed. Silently, I listened to my brother's soft sobs as a lump formed in my throat, and as everything went black I accepted the facts that laid before me since the start of this day.

Asriel will die.

And it's all my fault

Many Years Later...

The dump was far from a glamorous location. But W.D. Gaster, Head Royal Scientist of Monsterkind, would be lying if he said that it didn't provide about half of the equipment he needed when making some of his most groundbreaking inventions. Plus, it was free.

It was during one of his visits to the Dump when he made quite a find: a human's remains.

Admittedly there wasn't much of it, it was quite literally just bare bones, but Gaster knew that within these remains is a gold mine of information about humans, and most importantly, their souls.

And if it didn't contain anything, then at least the unfortunate nameless human deserved a proper burial. So he inched it out of the trash and with the skeleton in tow, headed straight to his lab.
