Author's Note

Prologue complete. This was pretty short since the actual beginning of the game is short and self-explanatory in itself. Now to those of you who haven't played Undertale I highly suggest you don't read this fanfic since most of them would probably be spoilers. Now before I continue this is the True Pacifist version of the fanfic which means I WILL be writing a sequel to this which will be the Genocide route of the game.

Chapter 1 Part 1: The Ruins: Killed or be Killed

Cadence groaned as she lifted her head from the ground. She didn't exactly remember what had happened except the fact she fell into a large hole near the summit of Mt. Ebott. How long she fell she couldn't tell. She didn't even remember why she was climbing Mt. Ebott in the first place. Looking around she found herself in a small room with a patch of golden flowers underneath her.

"Well thank Celestia these broke my fall," she said. She looked up to see the entrance to the hole high above her. She would be able to fly but probably wouldn't make it halfway before her wings got tired and gave out. "Well great looks like I have to find another way out of here," said Cadence. She looked around her surroundings to find nothing but a single pathway leading forward. "Welp forward it is," said Cadence getting up. She started down the path which eventually led to a small purple archway. To her curiosity she walked through to see what was on the other side. She soon found herself in a larger room with a small ray of light shining down on a small yellow flower like the one she saw back where she started.

She took a step forward only for it to start talking,"Howdy I'm Flowey, Flowey the Flower,"

"Mother of Celestia it talks!" yelped Cadence.

"Of course I do," said Flowey smiling. "By the way you're new to the underground ain'tcha?"

"Underground?" asked Cadence.

Flowey nodded,"Boy you must be co confused, someone outta teach you how things work around here,"

"Well yeah help would be nice," said Cadence.

"I guess little old me will have to do," said Flowey.

"You?" asked Cadence.

"Ready here we go," said Flowey.

"Wait what?" But just as Cadence asked, a small red heart appeared in front of her chest. A small yellow rectangle with the letters HP and 20/20 appeared next to her name and the letters LV. Four orange boxes appeared in front of her each one reading different words. The one on her very left was the word Fight with a sword symbol next to it. Next to the fight option was the Act option which had three small curved lines pointing out left. The third box read Items and had a small bag symbol next to it. The final option read Mercy with an X symbol next to it. "Ohhh kay this just got really weird," said Cadence.

"See that little red heart?" Flowey asked.

Cadence looked down and nodded,"Yeah,"

"That's your Soul the very culmination of your being," said Flowey.

"Huh figures," said Cadence.

"Your soul starts of weak but can grow stronger if it gains a lot of LV," said Flowey. "What's LV stand for?"

"Level?" asked Cadence.

"Why LOVE of course," answered Flowey.

"Oh," said Cadence.

"You want some LOVE don't you?" asked Flowey.

"Don't we all?" asked Cadence.

"Don't worry I'll share some with you," said Flowey winking. Suddenly small white pellets appeared and hovered around Flowey. "Down here LOVE is shared through Little White Friendliness Pellets," giggled Flowey.

"Friendliness Pellets?" Cadence asked.

"Are you ready move around get as many as you can," said Flowey.

"Alright," said Cadence reaching out. But when she touched one of the pellets, a strong pain filled her hoof forcing her to pull back. She looked over to the rectangle only to find a sliver of yellow and her HP down to 1. "What in Equestria?" Cadence yelped. She looked up to see Flowey smirking demonically.

"You idiot," Flowey laughed.

"You lied to me," Cadence winced.

"Well duh in this world it's Kill or be Killed, why would anyone pass up an opportunity like this," laughed Flowey. Suddenly more of Flowey's "Friendliness Pellets" surrounded Cadence as Flowey screamed,"DIE!!!" Flowey began to laugh as the pellets began to close in on Cadence. Suddenly the pellets disappeared and her HP bar shot back up to 20. Flowey looked around confused as a single flame appeared next to him and knocked him out of the room. Just then a bipedal goat wearing a purple and white dress walked in smiling.

"What a terrible creature torturing a poor innocent youth," said the goat.

"I beg your pardon?" Cadence asked.

The goat obviously realized that Cadence wasn't a filly,"Oh well this is interesting I was most certain that a child was here," said the goat.

"Yeah well I'm no child," chuckled Cadence.

"Ah whatever I'm Toriel the caretaker of the Ruins," said the goat.

"I'm Cadence," said Cadence.

"Well nice to meet you Cadence," said Toriel. "You see I come here everyday to check to see if any child has fallen down here, but it seems I found something more than a child,"

"Sorry I hope I didn't disappoint you," said Cadence.

"No, no it's fine really better than nothing I suppose," said Toriel.

"I guess that's true," said Cadence.

"By the way you're new here right?" asked Toriel.

"Yeah," said Cadence nodding.

"Very well then follow me I shall guide you through the catacombs," said Toriel walking off.

"Alright then," said Cadence following her. Cadence followed Toriel out of the room eventually ending up in another room but this time there was another entrance just behind a small patch of red leaves where a small yellow light flashed in the center next to two set of stairs. Cadence walked over and touched the light with her hoof as a small white text box appeared.

"The shadows of the ruins looms above you, filling you with Determination, HP fully restored," Then two options appeared before her one that read Save and the other that read return. Confused, Cadence decided to "SAVE" her progress and hit the Save option with her hoof. After saving Cadence ran after Toriel eventually leading into another room.

"Being here in the underground monsters will attack you," said Toriel. "When that happens you'll enter a battle, strike up a friendly conversation,"

"You mean I have to talk to monsters?" asked Cadence.

"Of course we don't want to hurt anybody now do we?" asked Toriel.

"No I guess not," said Cadence.

"Ok let's try it on this dummy, select Act to talk with it and I'll come in to resolve the conflict," said Toriel.

"Oh alright then," said Cadence. She reluctantly walked up to the dummy and gave it a little tap throwing her into a battle sequence. A small white text box appears before her,"It's a Dummy," Cadence pressed the Act option and pressed talk. "Uh hi there I'm Cadence,"

"..... The dummy doesn't seem to be interested in a conversation, Toriel is happy, you earned 0 EXP and 0 gold,"

"Well done Cadence," said Toriel.

"Um thanks?" Cadence said confused.

"Now come along," said Toriel. walking out the door. Cadence shrugged as she followed her out.

Author's Note

Chapter 1 complete. So now Cadence met Flowey and Toriel but her adventure is just starting. Something I should mention is that I WILL be skipping over certain moments in the moments such as the puzzle that Toriel teaches Frisk only because it takes too much time. Plus some of the dialogue might not be accurate so please bear with me.

Chapter 1 Part 2: The Ruins: Vs. Toriel

Cadence stopped short as a small white frog jumped out in front of her. Ever since she walked away from the save point nothing had attacked her until now. Unfortunately for her she only managed to take four steps before the frog attacked her. A white text box appeared in front of her as usual. Froggit hops towards you

"What in Equestria?" Cadence asked. Confused, Cadence decided to play along as usual and selected the Act option which allowed her to choose one of three options.

Cadence pressed the Compliment option an said,"You look nice today,"

Froggit didn't understand what you said but was flattered anyway. Suddenly Toriel appeared from the side and glared at the Froggit forcing him to hop away. You Won! You earned 0 EXP and 0 Gold

Dumbfounded, Cadence decided to shrug it off and continued to follow Toriel into a room with a large spikes popping out of the ground, around it was nothing but water.

"This is the puzzle but, just stay close and follow me," said Toriel. Cadence gasped as Toriel was about to step foot on one of the spikes only to see in shrink back into the ground. "Come along now," Toriel called out to her.

Cadence took one look at the path and shook her head,"Nope," Toriel had agreed to help her but walking over this was too risky, spreading her wings she jumped up and flew across the path and landed on the other side completely unharmed. Toriel was obviously amazed by this.

"Wow you did it?" Toriel said feeling outsmarted. Cadence shrugged and waited as Toriel quickly made her way onto her side of the room. "Puzzles seem too dangerous for now," she said walking into the next room. Cadence had expected there to be a room full of traps, but when she entered she found it to be completely empty.

"You have done excellently thus far, however I have a difficult request to ask of you," said Toriel.

"Difficult request?" Cadence asked.

"I would like for you to walk to the end of the room by yourself," answered Toriel. Cadence just looked at her as if she was being stupid. "Forgive me for this," Cadence watched feeling ridiculed as Toriel ran off. Shrugging, Cadence just started walking towards the other side like she did normally. As she walked she noticed that the room seemed a little long than usual. When she reached the end, Toriel ran out from behind the pillar nearby. "Greetings Cadence, do not worry I did not leave you," said Toriel.

"And why would I need to worry?" asked Cadence.

"Uh well...." Toriel didn't have an answer for that. "Well you see I just wanted to test your independence,"

"Oh kay?" Cadence asked raising a brow.

"You see I have to attend to some business so I have to leave you for a while," said Toriel.

"I see," said Cadence.

"I know I'll give you this cell phone to hold onto," said Toriel pulling out a small phone. Cadence took the phone with her magic and turned it on. It wasn't much but it had Toriel's number already imputed. "Be good Cadence," said Toriel running off.

"Oh well guess I'm alone," said Cadence advancing into the next room. She quickly noticed another save point nearby and decided to save, but before she could even take one step her phone went off.

"Hello?" Cadence asked.

"Hello this is Toriel, you have not left the room have you?" Toriel asked. Cadence bit her lips feeling a bit guilty. "There are a few puzzles up ahead I have yet to explain, it would be dangerous to try and solve them yourself," said Toriel. "Be good alright?" Toriel asked before hanging up.

"More puzzles huh, well won't hurt to try them," said Cadence. "But first," she walked over to the pile of leaves and tapped the light. Playfully crinkling through the leaves fills you with determination, HP fully restored. Cadence selected the save option and moved on.

From that point forward Cadence continued to spare monsters and eventually reached another save point. After saving she headed into the next room. Up ahead she noticed a ghost lying down in a pile of leaves.

"zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz (Are they gone yet?) zzzzzzzzzz," This ghost keeps saying 'Z' out loud repeatedly pretending to sleep.

"Well," said Cadence.

Move it force? Two options appeared Yes, or No?

"Yes," said Cadence. However upon coming in contact she was thrown into a battle. Here comes Napstablook

"Ok check," said Cadence going into Act. Attack 10 defense 10, this monster doesn't seem to have a sense of humor....

"Oh I'm real funny," moaned Napstablook. Suddenly tears began to rain onto Cadence forcing her to side step in order to avoid them. The faint odor of ectoplasm permeates the vicinity.

"Alright cheer," said Cadence selecting Act . You give Napstablook a patient smile

"Heh, really not feeling up to it right now sorry," said Napstablook. Napstablook looks a little bit better

"Can't spare so cheer," said Cadence. You told Napstablook a little joke

"Oh uh what's a hammer's favorite snack?" Cadence asked.

"What?" Napstablook asked back.

"Pound Cake," Cadence smiled.

"Heh, heh," giggled Napstablook. But even after the joke Napstablook started to cry again. Cheering seems to have improved Napstablook's mood again.

"Can't spare you yet so cheer," said Cadence. Napstablook wants to show you something.

"Let me try," said Napstablook. Suddenly his tears started floating up to his head forming a little hat. "I call it dapperblook," "Do you like it?" he asked. Napstablook eagerly waits for your response.

"Of course I do," chirped Cadence. Suddenly the battle ended.

"I usually come to the ruins because there's nobody around," said Napstablook. "But today I met somebody nice, oh I'm rambling again I'll get out of your way," said Napstablook as he vanished.

"Well then that was nice I guess," said Cadence. With that she continued forward.

After several more puzzles and monsters and several calls from Toriel, Cadence eventually reached a small house. Just as always she saved before going in. Seeing a cute tidy house in the ruins gives you determination, HP fully restored. Walking in she was instantly greeted by Toriel herself.

"Oh hello again I don't know how you managed to get here on your own but you must be exhausted," said Toriel.

"Yeah I am," said Cadence. "By the what's that smell?"

"Oh that, it's Butterscotch and Cinnamon Pie," answered Toriel. "I thought I might want to celebrate your arrival, I want you to have a nice time as possible,"

"Gee thanks Tori but you know, you didn't have to do this for me," said Cadence.

"Oh nonsense now come along, I will show you to your room," said Toriel. Cadence didn't need to argue she was already feeling quite tuckered out from today and just wanted to go to sleep. "Here it is, make yourself at home," she said walking back towards the kitchen. Cadence opened the door and walked, first thing she noticed was how clean and tidy the room was, but as if right now she just needed some rest. She hopped onto the bed and closed her eyes.

When she woke up, Cadence noticed the room to look a bit darker than before. She didn't know how long she had been asleep for but she felt perfectly refreshed. Getting out of bed she noticed a plate with a piece of pie on the floor next to her bed. You found a slice of butterscotch-cinnamon pie. She picked it up and placed it in her inventory. Now that she was up, she had to figure out a way to get out of here, maybe Toriel had some answers. She walked out and headed towards the living room where she found Toriel sitting on a chair near the fireplace.

"Oh up already I see," said Toriel.

"Yeah," answered Cadence yawing.

"Well I can't tell you how glad I am that you are living here," said Toriel.

"Um actually about that," said Cadence. "I have some business back up on the surface so I was wondering when I can go home,"

"What.... this, this IS your home now," said Toriel. "Um would you like to hear about this book I'm reading, it's called 72 uses for snails,"

"Um sounds great and all but I REALLY need to go back, so where's the ruin's exit?" asked Cadence.

"I have to do something, stay here," said Toriel getting up from her seat.

"What?" asked Cadence. But before Cadence could ask anymore question Toriel ran off. The sound of footsteps going down stairs could be heard. "Hey Tori wait!" Cadence called out running after her. Cadence had found her standing in the basement.

"You wish to know how to return home do you not?" asked Toriel. "Ahead of us lies the end of the ruins, a one way exit to the rest of the underground, I'm going to destroy it, no one will ever be able to leave again,"

"What why?" asked Cadence following Toriel.

"Every pony that has fallen down here has met with the same fate, I have seen it again and again, they come, they leave, they die," said Toriel. Cadence's heart froze, the thought of the ones before her hadn't been a thought up until now. "You naive mare if you leave the ruins......they, Asgore.... will kill you, I am only protecting you do you understand, go to your room," said Toriel.

"But Tori wait," said Cadence.

"Do not try to stop me, this is your final warning," said Toriel.

"Tori please just listen to me," said Cadence. She eventually found Toriel standing in front of a huge purple door.

"You want to leave so badly?" asked Toriel. "Hmph you're just like the others, there is only one solution to this, prove yourself.... prove to me you're strong enough to survive," Suddenly Cadence was thrown into a battle against Toriel. Toriel blocks the way.

"Oh no, alright I'll check," said Cadence. Attack 80 Defense 80 knows best for you. Suddenly multiple balls of fire appeared around Toriel and flew at Cadence. Toriel looks through you.

"Toriel Stop!" Cadence cried pressing the talk option. But Toriel continued to attack. Toriel looks through you. "Tori please!" Cadence cried out close to tears. Even so Toriel did not halt. Cadence continued to avoid the flames. She quickly decided and hit the Spare option. But Toriel gave no response and continued to attack. Toriel looks through you,"Spare," Again Toriel gave no response. Toriel prepares a magical attack. "Spare," For the third time Toriel gave no response. Toriel is acting aloof. "Spare,"

".....?" Toriel looks through you.

"Spare,"

"What are you doing?" Toriel asked as she attacked. Toriel takes a deep breath. Cadence quickly looked over to her HP, it was down to 10.

"I'll keep sparing you Tori," Cadence called out.

"Attack or run away!" Toriel ordered. As Toriel launched another attack Cadence's health was driven to 1. Toriel prepares a magical attack.

"Spare,"

"What are you proving this way?" Toriel asked. Cadence's legs trembled the burns on her body stung, tears in her eyes were rolling down her cheeks and she was sweating like crazy. She closed her eyes to prepare for Toriel's next attack only to find out that she was completely missing every move. Toriel looks through you. Confused Cadence once again selected Spare.

"Fight me or leave!" Toriel ordered. Once again her attacks were missing Cadence.

"Spare,"

"I know you want to go home but," Toriel stopped short.

"Spare,"

"But please go upstairs now," Toriel pleaded.

"Spare,"

"I promise I will take good care of you here," Toriel said.

"Spare,"

"I know we do not have much but,"

"Spare,"

"We can have a good life here," said Toriel.

"Spare,"

"Why are you making this so difficult?" Toriel asked close to tears.

"Spare,"

"Please go upstairs," Toriel begged.

"Spare," Toriel said nothing. "Spare,"

"Ha ha," Toriel chuckled.

"Spare,"

"Pathetic, is it not I cannot save even a single mare," said Toriel.

"Spare," once again Toriel said nothing. "Spare,"

"No I understand, you would be unhappy trapped down here, the ruins are very small once you get used to them, it would not be right for you to live in a place like this, my expectations, my loneliness, my fear, for you Cadence I will put them aside," said Toriel. With that the battle ended.

"Tori," said Cadence tearing up.

"If you truly want to leave the ruins, I will not stop you, however when you leave, please do not come back.... I hope you understand," said Toriel. Cadence ran over to her and hugged her sobbing quietly. "Goodbye Cadence," With that Toriel turned around and walked back where she came from. Cadence wiped her tears and opened the door to move on. Looking back to say one last goodbye to the ruins she advanced down the path.

"Sweet Celestia what a long hallway," said Cadence making her way towards the arc on the other side. Once she reached the arc and passed through it, she noticed a small ray of light shining down on a small patch where Flowey was waiting for her.

"Clever, verrrrryyy clever," said Flowey.

"Oh it's you again," groaned Cadence.

"Well of course, by the way you think you're really smart don't you?" asked Flowey.

"What do you want Flowey?" asked Cadence.

"In this world it's kill or be killed, so you were able to play by your OWN rules, you spared the life of a single person," cackled Flowey.

"Yeah so what?" asked Cadence.

Flowey chuckled,"I bet you feel really great, you didn't kill anybody this time,"

"Why would I?" asked Cadence.

"I don't know, what if you meet a relentless killer?" countered Flowey. Cadence clenched her teeth together, she really hated this thing. "You'll die, and you'll die, and you'll die, until you tire of trying, what will you do then?" "Will you kill out of frustration or will you give up entirely on this world and let ME inherit the power to control it?" Cadence didn't want to answer. "I am the prince of this world's future, don't worry my little monarch my plan isn't regicide, this is so much more interesting," Suddenly his face popped out of his head as he cackled demonically. Then he disappeared into the ground.

"You little freak," growled Cadence. At first she disliked Flowey for tricking her but now she pretty much hated him, but right now wasn't the time for that she had to keep going. She walked towards the arch and looked back. Hopefully things weren't gonna get worse as it already is.

Author's Note

Part 2 of chapter one complete. So now Cadence had her battle with Toriel and also met Napstablook. But now she'll be leaving the ruins and heading out to see the rest of the underground. Her next stop Snowdin Town. Where she'll come face to face with two skeletons.
