((Chara P.O.V))
I fell down here.... I wanted to kill myself... so badly. I can't take anymore pain... the misery. I need it all to end, this will have to work.
I felt my arm hit the ground... did I die? I opened my eyes, startled to see the blinding light from above. I heard a voice... a voice that I've never heard before.

"Howdy! You've fallen... here ill help you!" The voice said. I felt as the being picked me up, just enough to where I can stand. "My name's Asriel!" He said with a calm smile. "What's your name?... Chara. That's a nice name!" He said after I gave him my name. "Why where you climbing the mountain?" Asriel stayed calm. I told him I tried to kill myself. "Oh... thats not a very nice reason." He said as he looked away. "Here, come with me!" He said as he was holding his nice warm paw out for me to grab. I did.

I met his parents.... Toriel... Asgore. They where kind. I wondered now, why did the humans... do this to them. Ban them into the underground, for them to... to rot! I promised Asriel. Me and him would save human's and monster's lives!, and.. restore humanity! But..... we... failed.

I came up with a plan... we didn't tell the king and queen. They knew nothing of this. I started our little game. I ate the poisonous buttercup flowers found in our royal garden. I later died and let Asriel absorb my soul. We became a god. My plan was to punish the humans for all they had done to me and them, the monsters. Asriel carried my body to be placed into my home Garden of golden flowers, I said this to keep Asriel from really knowing... They would pay. Until....

Asriel stopped me. He held back our true power. And we later both died, leaving no trace of his or my soul. We where... just. An awful thought.

**About 1000 years later.**

The 7th humanfell into the underground. And... they finally... after all these years had remembered my name. CHARA. I would take control of them... and start killing monsters for killing me. Ha, sorry Azzy. I have work to do. I arrived at the ruins and saw my mother, Toriel. Or Mrs. Dreemurr. I took control and killed her off first. Seems she noticed something, that the human... the one I was controlling, had a faecal expression, she described as, "My... Child. You look like you've seen a ghost!" Toriel said, as she blocked the way.

I knew what I had to do.... I "HAD" to kill her. When I took the final blow.... she... she collapsed and said that she wasn't protecting me... but them. The other monsters. I go outside of the ruin doors. Oh? What's this.... after all this time i now come face to face with my brother. Asriel. He looked different now. He had no soul like I did but can tell I was there. He looked at me and talked about our old plan... one to kill humans? He said "That's a wonderful idea!" And ran off. I opened the doors to my once living in, Snowdin!
