Dammit, you hated your life. Hated all those stupid people living in the tiny town beneath Mount Ebbot. Hiking, running, climbing- all of these things took your mind off how alone you were, down there. Nobody to talk to, to empathize with. Now you were up on your mountain, with only the wind to keep you company. Nobody came up here anymore except for you. After all, who would want to be on THIS mountain? You'd made it look like it was haunted, playing tricks on the hikers and nature-lovers that came here sometimes, and the disappearances of those six people had only helped you to do so. But… was that singing? You listened, letting the wind carry the voice to you. It was coming from your left! You started walking quietly that way so you didn't lose the noise.
Now it was louder, now it was fading, maybe it was just the wind dying down, but then it really was gone. You backtracked, found it again. It was coming from the right this time… it was coming from the cave? You peered inside. Nobody. But there was a big hole in the floor, maybe someone had fallen down and was singing, had been shouting, but then, the wind had carried it away from your ears. You crept forward, cautious.
As you reached the edge of the chasm, a huge blast of wind shoved you forward. You skidded forward, your sneakers drawing shrieks from the stone floor. You were practically level with the floor as your toes peeked over the edge. You flipped, lost another few inches of ground. Now your feet were completely over the edge, and you were still losing to the wind. It was as if some kind of magic were trying to pull you into the pit. You looked around for anything that could help you. There was nothing but a crack in the ground that you hooked your fingertips into. As the gale intensified, you were pulled into the pit,your fingertips sheared off by the sharp stone of the crevice. You shot back, hovering over the abyss for a second, before the wind seemed to shove you down.
Your flesh dissolved away from you as you fell, turning to dust above you. Your shirt suddenly bulges and you lift it up to reveal your newly-exposed ribcage and… and... and all your organs underneath. As you watched, they turned to dust, escaping as if your shirt had been a dam, along with the rest of your skin turning to powder above you. You were now only bones.
You felt like you'd been falling forever when you finally hit the ground, but also not really; you'd landed on some yellow flowers that were beautiful, and also extremely tough apparently- they weren't crushed in the slightest, and the only thing hurting was your head. You took inventory of yourself, making sure nothing was broken. Then you just lay there for a minute, trying to absorb what had just happened, until your dust began to powder the landscape.
You decided to move on. You went into the next room and saw another of those yellow flowers, this one much more sickly-looking than the others. You got a little closer to better look at it when it turned to you with a big smile and said, "Hi! I'm Flowey the flower! Are you new to the underground?" You nodded. This place was called the underground? Truly, an imaginative name. Almost as good as Flowey. "Well, I guess I ought to show you how things work around here!" As he spoke, his cute grin turned twisted. "In this world it's kill or be killed. For example, if you had been a human, I'd have killed you and taken your soul. But since you're just a skeleton, it's not worth it."
"Why?" You asked. His sickening grin became even more evil. "Why? Because human souls are much more powerful than monster souls! They give you hundreds of times more strength than a monster soul! I've almost gotten four so far, but that idiot goat lady almost killed me! But I got lucky twice! I now have an orange soul and a blue soul!" As he spoke, you were slowly backing away until you reached the entrance to the rest of the underground. As he continued his rant about souls, you turned and ran from the evil buttercup.
Once you were sure you were a safe distance from the demented flower, you slowed to a slow- and more importantly silent -walk. You wanted to avoid any more monsters. You had a few close calls with monsters while maneuvering the ruins, but you decoded the puzzles with ease. You explored everywhere, the spider bake sale, the room with the slides, until you came across an odd tree. You gazed at it, captivated. The tree was enormous and covered in bark that was black and pitted. Any leaves that grew turned a bright red in seconds, then dropped to the ground, where an insane amount of them already had fallen. While you were staring, you didn't notice the goat-like figure walking towards you, lost in thought. As she walked by, she bonked your shoulder, bringing you back to reality. You jump away, letting out a strangled shriek. She turned and looked at you with kindness. "Oh! I'm sorry! I was lost in my thoughts and I wasn't exactly paying attention to where I was going! Please forgive me!"
Wow. For a 'kill or be killed' world, this lady seemed pretty nice. And she was a goat, sort of. You remembered Flowey saying something about a goat lady almost killing him. Any enemy of his was a friend of yours. She practically dragged you over to her house to see if you'd been hurt, then she offered you a slice of still-hot butterscotch-cinnamon pie, which turned out to be delicious. You asked if there was any way out of the ruins, because all you'd found were dead ends. She nodded, seeming sad, like she'd wanted you to stay.
It was then you decided to trust her on a whim. You told her you'd come from the surface, that you'd been a human, that you'd been dragged into the chasm that led here by a strange wind, and that while falling, you'd… decayed. Then you told her about Flowey and what he'd said, why you'd decided not to interact with any monster, to try to escape from here.
She appeared to be in shock. It wasn't really that surprising, though. You were probably in shock yourself. After all, it wasn't every day one became a bag of bones. You realized suddenly that Toriel, as you now knew her, was talking.
"My child, there is a way out of the ruins, but I feel like I should prepare you for the world outside the doors before I let you go. And I have a friend who may take you in if I ask him. You stared eagerly at her, waiting for her to say more. "I mean, my child, that I shall reach you magic
