(This takes inspiration from Orphan Au. Also, in this Dipper is really OOC but anyone can be if you write them in an abusive environment. As for Mabel well she might be a little OOC but that's due to my difficulty in writing her personality.)

Long ago, two races rules over the earth. Humans and monsters. One day war broke out between the two races. After a long battle the humans were victorious. They sealed the monsters underground with a magic spell.

Many years later…

MT. Ebott 2012

Legends say that those who climb the mountain never return.

Twins. Mabel Pines and her brother Mason "Dipper" Pines. Ran up the mountain as fast as their 12-year-old legs could carry them. Why? They were alone and had only each other. Both their parents are dead, and they were put into an abusive foster home.

When everyone was asleep, they snuck out, but Mabel yelled in worry when her brother hit the ground hard waking everyone up. When the foster family took notice of them leaving, they ran with the whole family after them.

Despite everything that happen Mabel still wants to make friends with everyone. She had a pig once, but their foster family thought it would be fun to kill it she cried for several days and Dipper got a beating for throwing a lamp at their foster brother blinding him due to the glass going in his eyes. Was he proud of himself yes, did he regret it, absolutely not.

He planned for so long for them to escape and the only thing he could come up with was this mountain he read about in history books. A place no one returns, he always assumed it was suicide and him and Mabel both agreed death is much better then living with these people. They looked down the hole and to each other.

"Ready brobro?" She asked her brother while clenching his hand.

"Yeah." They both ran and jump in the hole. Ready for the embrace of death to come for them but before they hit the ground they were knocked out by the pressure of the fall.

Dipper woke up first seeing he was alive and landed on a bed of flowers and Mabel was right next to him. "What the hell." He mumbled he stood up and looked around a bit, not going far away from Mabel. He noticed how he was in an underground ruin of some sort. He looked up and saw that the fall had to have been for miles yet somehow, he and Mabel aren't dead.

"Mabel, Mabel! Wake up!" He yelled shaking her. The girl opened her eyes and saw her brother alive and well and jumped hugging him.

"Dipper I'm so happy were alive!" She yelled, if she were to be honest, she was scared of dying but somehow, she and her brother survived the fall.

"Come on Mabel. There's a door over there. Let's go see if it leads anywhere." She nodded hand in hand. They walked through a door. It was a dark empty room where the only source of light was focused on one flower in the middle of the room.

"Dipper look the flower is so pretty! Maybe I can make a necklace out of it." Mabel exclaimed. She went to pick it, but the flower turned around with a smile on its face. Dipper could see through it Mabel however could not.

"Howdy, I'm Flowey. Flowey the flower. The flower said with a friendly smile on his face. This caused Dipper to glare even harder at Flowey. "Your new to the underground aren'tcha."

"Underground? You mean that place the monsters were banished to centuries ago?" Dipper asked

"Looks like you know your history kid. But golly you both be so confused on how things work around here. Don't worry your friend Flowey can help you understand how the underground works."

"Really! Thanks!" Mabel said happy she made her first friend while Dipper gave Flowey a hard glare.

"Ready? Here we go." A red glow came from Dipper's and Mabel's chest in the shape of a heart.

"What are you doing to us!" Dipper demanded

"Me? Nothing. Those are your souls." 'The boy has determination and the girl has kindness' "Your soul is the very culmination of your being. It starts off weak, but can grow strong if you gain a lot of LV."

"Yeah right." Dipper huffed

"Come on Dip and dots. Trust him he's trying to help us." Dipper rolled his eyes. "For you Mabes. What is LV."

"Why LV stands for LOVE of course." Flowey explained to the both answering Dipper's question. "You want some LOVE?"

"Yes!" Mabel shouted

"No. Mabel were leaving." He grabbed his sister's wrist dragging her away. That plant was messed up and was about to try to kill them.

"But Dipper he was going to be our friend!" Poor Mabel naïve and always optimistic. Dipper was going to say something to her, but they heard an eerie laugh. They looked back at Flowey who was now emitting killing intent.

"You know whats going here don'tcha boy!" Flowey said with the most sickening smile on his face. Dipper didn't need to answer as he glared at the flower. "In this world it's kIlL oR bE kIlLeD!" He told them in an echoey voice sending thorny vines at the twins knocking them back.

"You know boy there are other ways to gain LV! Shutting yourself out, injuring one, murder. Yet unlike you sister who's a LV 1 your already LV 6." Flowey cackled as he sent seeds at Dipper at high speeds aiming for his soul. Dipper dodged and found a stick picking it up. Mabel was out cold so she couldn't help but Dipper ran at Flowey who sent vines past Dipper at towards Mabel.

"I can play any game. Even this one. In no way can you kill me being so weak so take a step further and I'll kill her first." Dipper knew what that meant, Flowey wanted to kill him then Mabel. He knew it the only one he can trust is Mabel. "Die!" He sent the vines at them, but a fireball came flying at Flowey who noticed and escaped at the last second.

"Oh, my are you alright. I hope that horrible creature didn't hurt you children that much." The goat lady said picking up Mabel. "She's in need of medical attention. That Flower gave her a mild concussion. She should be fine."

"Who are you?" Any chance of him trusting anyone now is gone when Flowey attacked him and Mabel. He wanted to take Mabel from this goat lady and run but he doesn't know this place, so he reluctantly allowed her to take Mabel.

"My name is Toriel child. May I ask for your name?"

"She's Mabel and I'm Dipper." He tried his best to be polite.

"It's a pleasure to meet you." She smiled as they came across a Foggit. Toriel didn't move like she knew this would happen. The Frog like creature just said ribbit and sent those pellets at Dipper a few hitting him but the rest he dodged. He ran at it with a stick with a hard swing killing it. "Oh dear, you were supposed to act and befriend it. It's ok though." While she was very uncomfortable at the child killing a monster none the less, she held no remorse for him or any hate. Just pity for what he must have gone through to lash out the way he did.

"Oh dear." They made it to the end of the hall. "Dipper please hold my hand this is a very dangerous puzzle if done in correctly."

"No, it's fine I'll just follow." He said, his main priority is Mabel's safety. As Toriel took a step on the spikes, Dipper thought her foot was going to be impaled but the moment before her foot touched the spike it retracted into the ground. Dipper not wanting to get far behind walked the same path as the goat monster who was being careful the whole time as to not drop Mabel.

Making it to the end and through another room with a dummy. Toriel had him 'fight' it. He decided to amuse her and hug it. She seemed very pleased with this something he was fine with no matter how uncomfortable hugging the dummy made him.

They entered another hallway. Toriel stopped with him behind taking notice of Mabel's condition. She used a free hand to reach into her pocket for a phone and handed it to Dipper. "I'm sorry the child's injury is worse than I thought. I must hurry to my house to treat her immediately." Dipper wasn't convinced at first but then he looked at his sister's motionless body and saw blood dripping from her head from when Flowey slammed her against the wall.

"I'll call you the moment she wakes up. If you wish to come to my house and keep an eye on her you may. The ruins are a straight path. Once you get to the end that's where I reside." Toriel told him as he took the phone and she ran off as fast as she can with Dipper standing there motionless. 'Mabel, I failed you as a brother once cause of that flower. To keep you safe I'll kill them all'

Once he got over his shock, he walked down the corridor to the next room. He saw a Froggit standing there next to an opening. Before going through it he killed the Froggit without it noticing and walked in. inside he saw a bowl of candy with a sign that says "Grab 1". Dipper rolled his eyes and took several handfuls emptying the bowl.

Deciding to check on Mabel he decided to call.

"Yes hello?" Toriel answered on the other end.

"How's Mabel?"

"Her injuries have healed and she's resting." She answered not wanting to talk anymore he hung up.

~Toriel~

"That child is quite troublesome, but his heart is in the right place. But no matter what he does I will make sure he follows the correct path." She loves children dearly and the thought of one with an LV as high as his makes her ponder what he's gone through.

"Perhaps leaving him wasn't the best decision." She knew what she was risking when she saw him kill the Froggit and his constant worry for the girl means he only cares for her. And if anything, he thinks can threaten her he will not hesitate to hurt or kill.

"That boy is so much like my dear Chara." She said walking into the bedroom where Mabel slept with a bandage around her forehead. "Impulsive, Intelligent, as well as having a strong bond with their sibling."

Mabel stirred a bit making motions she was about to wake up but stopped after a minute. Seemed her body was just getting into a comfortable position. She smiled standing up not wanting to think of her dead daughter anymore as to focus on the present. She decided to make her famous Butterscotch Pie for the boy when he arrives and the girl when she wakes.

~Dipper~

He killed the last monster in the area and he's never felt so happy. Free. Like nothing can walk over him anymore. He already got this toy knife and decided to practice with it for a bit before going to Toriel's house which he's already found.

He's practiced swing after swing on a pillar to see if he can damage it. The results were greater than he anticipated he managed to cut clean gashes on the pillars. He grinned and cut again and again until he caused a cave in where he was at. He couldn't escape in time and a large rock landed on him crushing his body.

'Mason promise no matter what you'll always protect your sister' A memory flashed in Dipper's head. These were the last words his father ever told him before hedied.

'No, I don't want to die! I still have to keep my promise!' He shouted in his head. Next thing he knows he's feeling the cold hard ground on his back. He opens his eyes and see's he's in front of Toriel's house. Earlier he found a floating star in front of it, so he snuck over and touched it without her noticing. He was so confused. Was him dying just a dream. It had to be, how else was he here right now.

"Well congratulations human." A voice said. Dipper recognized this voice as Flowey. He looked to his side to see the sadistic flower looking up at him.

"What are you talking about?" Dipper asked

"Your determination brought you back from the dead. Well more specifically back in time. The cave in you caused never happened and you now never died. But beings like us will always remember the other timelines while others will continue their lives as life nothing happened." 'Except that smiley trash bag' Flowey told the boy whose eyes went wide at this new revelation.

He was going to asked Flowey what else he can do out of curiosity but when he looked over the Flowey was already gone. He sighed and walked off quietly to process this new information. He pulled out his phone.

"Hello?"

"It's me. I think I'll just explore the ruins overnight. I'll see Mabel in the morning. I need to clear my head."

"Very well child. But don't hesitate to call if you need help."

"Bye." He hung up and walked off somewhere. "Maybe killing something will help." He dropped the phone not planning to hear from the goat anymore.

~Mabel~

Mabel opened her eyes to see she's in a bed. Not the one she has with her foster family. Not that she can called them family. She turned her head only to feel a sudden headrush and a shock of pain. "Ow." She groaned holding her head to minimize the pain. She eventually stood up walking out of the room and stumbling down the hall. She didn't even make it halfway before she collapsed to the ground.

"Child, you shouldn't be up yet." She looked up to see a goat creature mothering her. Oh, if it wasn't for this pain, she would be hugging her right now maybe calling her goat mom.

"What happened?" She can't remember much. The last thing she remembers is seeing a flower then nothing else. Toriel figured she was obligated to explain everything.

"You and your brother were attacked by a horrible flower. You were rendered unconscious with a mild concussion and was almost killed along with your brother had I not been in the area." She told the child the first part while carrying her to the living room and sat Mabel on her lap.

"Then what happened?" Toriel couldn't help but giggle at this girl's enthusiasm. Usually when a human see's a monster they scream or at least nervous but not this girl.

"Well I looked over your wounds and carried you here. I gave your brother a phone as to keep in touch since I'm well aware he doesn't want to come here." Mabel looked guilty at being told this. "There's nothing to be guilty about child. Many humans are distrustful to us."

"It's not that. Dipper is like that to everyone. I'm sorry if he said anything mean to you or hurt you."

"Even if he did, I would not hold it against him. When I looked in his eyes, I saw nothing but pain. His LV is also unusually high for someone like him."

"LV?"

"LV is an acronym it means LOVE. But LOVE is also an acronym it means Level Of ViolencE." Mabel felt cheated by this play on words.

"Well that's dumb."

"Yes, the person that came up with this acronym is quite dumb." Toriel told her but not wanting to talk about her ex she changed the subject. "Mabel was it do you like Butterscotch Pie?"

"Isn't Butterscotch old timey candy that's really hard?"

"Yes."

"Then I'd love some!" She said with a smile on her face as Toriel sat her in the chair as she went to grab a piece from the kitchen and bring it to the girl as well as a slice for herself.

"Your family must love your cooking! I know I do!" Mabel yelled taking another bite of the pie. Toriel frowned a bit at hearing those words.

"They did. I used to have 2 children myself." Toriel wanted to make a good impression on the girl but also get this off her chest. "One my own biological child Asriel and the first human to ever fall down here. I took her in and adopted her as my daughter. I miss Asriel and Chara deeply." Mabel got up and gave her a comforting hug to help her.

"I'm sorry I brought that up goat mom!" Toriel stopped crying for a minute and looked at Mabel with the strangest looked.

"What?"

"Well you look like a goat and your acting like a mom. So, I'll call you goat mom!" Toriel didn't get it but this little human girl had her laughing. She's been so lonely for so long and doesn't laugh this good unless her friend stops by.

"Come with me, can you?" Mabel followed her downstairs where a long hallway stretched out.

"Woah where are you taking me?" Mabel asked out loud

"You and your brother are far from the first children to fall down here. As a matter of fact, you both are the 8th and 9th. The rest have gone through this door and eventually died. Possibly to the royal guard or the harsh elements of the underground."

"Why didn't you stop them?"

"Dear child I've tried but none of them can take no for an answer. And I could never bring it upon myself to do them any harm, so I gave in and let them pass." She solemnly said.

"Oh, sorry."

"Mabel, somehow you've given me hope the monsters can live on the surface one day with humans. Can you promise me you'll do for them what you did for me? Give them hope?"

"Absolutely." Toriel opened the door for her but before Mabel went through, she ran and gave Toriel a hug. "Thanks goat mom. Can you tell Dipper I'll be waiting for him?"

"Of course. And I want you to have my son's phone." She placed Asriel's phone in her hand. "It'll help you and you can keep in touch with me on your journey."

"Thank you." She ran to the door and turned around with it closing with a big smile on her face. "Goodbye!" And the door closed.

"Goodbye, my child and good luck." Toriel trekked her way back up the stairs and decided to wait at the big tree for the boy to arrive to give him Mabel's message. She didn't have to wait long as Dipper showed up and approached her. The first thing that Toriel noticed was his hands were covered in dust meaning he killed the monsters.

"Child, I have been worried. Are you ok?"

"Fine." He said simply

"Look at you. Your filthy. All the dust your covered in. Come in and I'll run a bath for you afterwards you can eat and rest til morning." Dipper hadn't noticed it before, but he is a little dirty and hungry, so he decided to accept her offer on the bath and meal.

"Alright." He spoke following her into the house. Dipper was shown the room he'll be staying in and then followed to the bathroom where she ran the water for him. "Now please remove your cloths so I may wash them." Being a preteen boy, his face flushed red at the odd request not wanting to strip when someone else is in the room with him. "I can't with you in here!" He shouted, Toriel put a hand over her mouth realizing that apologized and walked out the bathroom and stood there as Dipper opened the door slightly and slipped his red shirt, vest, and shorts outside the door which she took and put in the wash.

~Time skip after Dipper eats~

Dipper has eating and taken a shower, eaten, now he's resting while Toriel did whatever. He had realized he'd forgotten to ask about Mabel as he saw no sign of her when he got here. His heavy eyes soon made him go to sleep.

~Mabel~

Mabel was walking through the snow. She would have been freezing had she not been wearing her shooting star sweater. She noticed it get darker but kept on going. Her foster family left her out in harsher before, so she didn't care all that much. Her head was still killing her.

"Ugh. Stop hurting already!" Mabel shouted which must have attracted something as she heard footsteps behind her. She turned and saw nothing there so grabbing her head she stumbled forward only to hear the footsteps again and a stick breaking. She turned and again nothing. "What the heck is going on?" She kept on going and saw a bridge up ahead stumbling as fast as she could to it but stopped when she heard those footsteps again. She wasn't going to turn around this time.

"Human." She felt shivers go up her spine but that could just be the snow. "Don't you know how to greet a new pal?" The voice asked
