Author's Note: I apologize that this prologue may be very… dull and uninteresting. I kinda… flopped. Don't worry, I don't actually know if it's bad, go ahead and read it. :) It's just not as descriptive as I would've liked. I kinda needed a way to actually start this, cause, well, when does a mortal randomly appear in a land of immortals? Anyways, the original idea of Reapertale is by Renrink, you can check out their Tumblr for the original comics. Reapertale is basically just an Undertale AU where the I suppose mostly main characters are gods. Unfortunately I can't start this fanfic with Frisk because I found it too difficult, so here's my OC instead!
I'm still debating on what Muffet should be, I was informed on the other ones but Muffet seems unclear. I would appreciate more information on this AU if anyone could offer it. ALSO! I'm thinking of doing updates at least once a week per fanfic, so chapters may be slow. I usually write about half of one in my free time after school, though.

Every human knew of the gods. There was Asgore the king, Toriel of life, their son, Asriel, of hopes, Undyne of war, Gaster of magic, Alphys as knowledge, and then the two most didn't give much a thought toward: Sans and Papyrus, the gods of death. No human mortal had ever seen the realms of these gods in a way other than dreams, but there were legends, myths, of the first human. Their name was Chara. As the goddess of life, Toriel was called to create a species for the gods to watch over. She had decided that she would create a race that could come in all shapes, colors, and sizes, and each would be different, but similar. They would be strong, kind, and DETERMINED.
With great thoughts, Toriel created the first human. A child. Innocent, smart, determined, caring. Everything Toriel had thought of came to life. Her creation was perfect, or at least almost perfect. Toriel took this child into her care raising the never aging child in her realm of life, how beautiful it was. And that was all they could remember… Something after that about the guardian of something.
They shrugged it off, they were taught this in what? Second grade? Later it was only the history of the human and monster world, wars, politics, all that stuff nobody cared about.
The mountain was quite refreshing. Beautiful gray and white stone, a nice chill wind whipped stray hairs into the human's face-which actually felt quite nice. The stone was wonderfully cool, the cloudy skies let small streaks of light dance across the stones.
Sometimes life wasn't all that miserable. This human had gone through many troubles. Most of which they would never like to think of again, but those troubles were exactly why they were here. Climbing Mount Ebbott. There were tales about this place, but humans and monsters, even with the technology they had created, never dared to come here.
The mountain was believed to be a sacred place, where the first gods met. Where Chara stood guard-what had ever happened to the first human? There were stories about a temple, they were sure. Something about being able to communicate or interact or enter their realm, something. Either way, this human was determined to have council with the gods. Toriel, Sans and Papyrus in particular. Life and death, they could both help.
Without seeming to stop, this human trekked the mountain constantly humming, singing and reciting poems and songs. Right now they were toying with weird rhymes.

How many rabbits can fit in a pot?

None of course or the hat would've rot!

Perhaps this human wasn't the most sane of their race, but they seemed to be having a jolly good time trekking that mountain. They wore a dark gray T-shirt with a beautiful little picture that matched the scene they were hiking in, a dusky, dark blue jacket with the sleeves rolled up, dark jeans that were just a bit too long, a pair of dark gray and blue sneakers, and a black scarf that covered most of their face from the bitter cold. Along with all that, they had a brown backpack that was nearly flat. All that was in there were one or two extra clothes, a couple of water bottles and plenty of snacks, none of it took up too much room.
So their odd journey continued. It had been two days since they'd been climbing, fortunately there was a nicely carved path to make life easier. Their clothes were still intact, which was quite a remarkable feat for a homeless one who was climbing a mountain with absolutely no experience whatsoever. But something worse was to come. Above them was someone whispering, or maybe talking, but it blended in with the howling of wind. These whispers though, they were of ill wishes, had the human heard them they probably would've darted for the nearest cave, and there were many of those in this mountain. Unfortunately, the human didn't dart into a cave. Only a minute after the whispers started, there was a loud noise, like a bird's screech mixed with a mighty dragon's roar. The human stopped dead in their tracks looking up to search for the noise. That was the last warning before disaster struck.
Above them the mountain shook. One mighty shake, and it felt like the world was collapsing. Boulders, rocks, sharp ones too. They all fell from above. The human was terrified, the look all too clear on their face, they dodged as much as possible. Perhaps they were homeless, but they certainly weren't slow. Rocks pelted them, scratching bruising, one even buried itself in their shoulder. As quickly as possible the wounded human dived into one of the caves landing on their back and crawling to the back of the cave as if something was chasing them. The falling rocks didn't stop, once the human entered the cave, the entrance was covered by huge boulders, and to make matters worse, the ceiling was also collapsing. There was no where safe, blood was slowly spilling from their shoulder, arms, legs, even face staining the pure rocks red.
When the human thought that it was all over, their life was going to be taken by the gods, and before they came, the human was going to painfully bleed to death, a large mound of soil fell upon their chest knocking all the air out, and their head bounced against the rock, their pulled back hair barely cushioning the impact.
Everything was black, there was no pain, no gods to watch for. Just the simple, endless dark. But through the thick dark, the human could hear voices. There was a deep, smooth one, and a higher, more…. How could you explain it? The voice simply sounded like Skeletor from He-Man. Maybe with a lighter tone to it though. How about, a cartoonish, light-hearted fellow with a slight accent? Did that explain it?
The human mentally shrugged to itself, and started to listen. There were only fragments, not full sentences.
"...they do? ….awakened….dangerous..." said the deeper voice.

"...kind… didn't mean… forgive… brother..." said the lighter voice.

"...right...judged..."

"...suppose...change your...hurry..."

They felt an odd pulling sensation as the lighter voice finished speaking. It was like someone was trying to pull out their soul. Maybe that was exactly what was happening? It was painful, unbearable, but with determination saved them. The will to live after everything was lost. They couldn't just let go now. Face full of now an odd kind of pain, the human knelt and concentrated. It felt a little over-dramatic and weird, though. Oh well, you had to do what you had to do.

Suddenly the pulling sensation stopped, the human was knocked back into the darkness.

"...not working….Chara…?"

"...possible...sure you're...what if…?"

"...check with..."

"...doesn't like..."

"Because…understand..."

That was the last of the conversation. The voices disappeared and the world was dark and silent again.
Except, there was the light sound of rain. First it was barely audible, but it kept growing until you could hear it splashing against trees and plants. It was a light rain, thankfully not a storm by how it sounded. Not too long after the rain sounded, the darkness faded. Soon the human vision was haunted by a bright light, that also faded into the world around them. Except… they weren't in a cave anymore with crumbling walls. They were in a forest. A dark forest.
At first it simply looked as if someone had drained most of the color from a forest at night, but after staring at it for a while, they noticed it was dead. A wilted forest. The trunks were bent, weak and gray, the grass was crippled and made a light crunching noise when the wind blew, and the rain made a hollow thumping sound against everything it collided with.
The human had landed on their side in this mysterious place, and carefully they turned to lay on their back. Immediately pain struck and they let out a huge gasp. This was certainly not a dream. Scratches still bled freely and bruises still ached. The metallic taste of blood crept into their mouth from cuts on their face, and a stone was lodged into their foot. Tears streamed down their cheeks, mixing with blood and dust while dripping to the ground. Slowly they lifted their upper-body off the ground, teary eyes closed in pain and teeth grinding in anticipation. Dragging their body to the nearest tree they relaxed and allowed the rain to soak them through.
Suddenly a strong wind came by, stronger than those on the mountain. In it, a voice was calling. Not any voice, one of the voices in the humans… "dream". More gusts of wind came, each one brought the chilling thought of death. Each time the wind came it got weaker, and the voice got stronger.
