Summary: This is the Underfell! AU Sans x Frisk and I hope you enjoy!
Prelude to Darkness**************
"Don't do it Sweetheart" Came a gruff voice
Frisk was at a loss at seeing Sans standing at the end of the hall casting an ominous shadow along the corridor.
"Frisk, I think we need to think a better strategy than to just waltz right through. Obviously Sans is here to stop us from reaching the barrier." Flowey said shaking in the boot he was being carried in.
Frisk took a step forward.
A bone pierced the ground right before Frisk's foot making a crack line across the hall.
"That's the line doll, cross it and I won't let myself be held accountable for what will happen. The choice is yours." He stated gazing blankly in their direction.
Frisk gulped. The only way to get back home and to save these monsters was to get around a very angry Sans. Slowly Frisk sat Flowey down behind the line for safety.
Frisk hadn't a clue what they had done wrong to make Sans suddenly angry to the point of stopping them on their mission but Frisk was determined to see this through to the end.
Frisk placed their other foot across the line.
"Do you wanna have a bad time? Last chance to back up and go back to Snowdin sweetheart, before things get ugly." Sans said with the atmosphere getting more intense at the promise of battle.
Frisk steeled their nerves and kept their foot down. They knew what they had to do even if they didn't understand why it had come to this.
"Frisk! Please let's do what he says! At least until you can figure out what's gotten into him!"
Frisk was set with determination and didn't budge.
Sans grinned menacingly letting his gold fang gleam in the light.
"Well then I don't know about you but it looks like I'm about to have a good time." Sans cackled with his vibrant red tongue accenting his primal instinct of violence.
His eye suddenly glowing with such a red ferocity it made Frisk's heart skip a beat.
Flowey wilted in horror at the sight before him. He had never seen this kind of magical potential before as Sans readied his attack.
"Oh Frisk, how did this happen? How did we not see this coming?" Flowey questioned to himself as Frisk walked straight towards the terrifying sans with arms wide open.
The Beginning of the End
Frisk had been one to explore and hike along old trails since they were little. It wasn't news to anyone that Frisk would disappear over school breaks with trail gear in tow. This however was a little different for Frisk.
This one trail hike seemed to call to their soul. To search for something that Frisk had no idea what they were expected to find. Frisk felt destined to find out about the grueling trails coursing through Mt Ebott. Especially when hearing of a so-called bottomless pit near the very top it made the soul resonate at the mere thought of the adventure to be had.
Gathering some supplies Frisk was ready to start their summer learning all the trails and secrets the mountain had to offer.
A simple drive maybe two hours tops at the most and Frisk would be at the foot of the mountain. Frisk couldn't help but shiver in anticipation at what scenery they would find and more importantly be able to take a deep breath and reflect before continuing on with life's big plans.
This summer was their last to enjoy before Frisk would pack up for dorms and move to the inner city college that they applied and were accepted to.
A big step and the thought of no longer having entire summers to themselves to explore set Frisk back emotionally.
There was a job to consider and a future that Frisk wasn't quite sure if what they wanted was truly for them. Prospects of a future relationship and possibly a family it was a little overwhelming but some reflection after a good long hike always made them feel better.
'Or I could possibly find someone mysterious, maybe even dangerous who will sweep me off my feet.' Frisk giggled at the thought.
Frisk found an old gas station near the mountain to pull over and hopefully get a map or some information while they stocked up on supplies and gas for the road.
Ever diligent Frisk went over the check list for their gear making sure before leaving they had everything needed to survive the wilderness.
Finding everything to their liking Frisk went over the map they had purchased while sipping a sweet cola as a treat for the hot day on the bench outside the store.
"Kids going to Mount Ebott? " said a clerk from within the station that pricked Frisks interest.
The open window behind them they purposely continued to look over the map while keeping an ear on the conversation.
"Yep, Seems pretty confident too." Said the clerk that Frisk had made their purchases with.
"That place is a living death trap! No one in their right mind would tackle those trails by themselves!" Exclaimed the elderly clerk.
"Oh Jenkins knock it off! Next you're going to say is that all the legends about monsters are true." Said the younger clerk.
'Monsters?' Frisk thought
"Monsters existed I tell you and they were all banished beneath that mountain many years ago!" Jenkins defended.
"Oh please."
"They were evil! They feasted on the souls and flesh of people and would continue to had they not been banished and sealed up in that accursed mountain!" Jenkins adamantly explained to his younger associate.
"Old folktales Jenkins just let it be. Besides the kid seems experienced and if it's too much to handle at least they'd figure it out before they got to deep into the trail. That place is brutal there is no denying it but it's not a death trap for those with experience." The younger clerk stated then signaled the end of the conversation by putting on the radio.
Frisk downed their beverage their mind racing.
'It's okay I'm in shape and I know what to do for emergencies so nothing is going to change my mind now. This needs to happen or I may never get the chance again!' Frisk calmed themselves knowing that the challenge was half the fun.
Picking up the map and gazing at the layout of the mountain and its many trails. None of which led to the top only mid points.
"How do I get to the top?" Frisk said out loud to be startled when they got a reply.
"The dusk trail" Said Jenkins who had come outside.
"It's not on the map" Frisk said scouring over the paper map.
"Of course it's not. People have disappeared to never come back taking the dusk trail." Jenkins glared at Frisk.
"I get the feeling you won't be telling me how to get there either." Frisk sighed sadly
"I can't say it would be wise for anyone to go to that mountain period. However you seem to have a good head on your shoulders and if you can make it to a certain point on snowy trail the decision will be yours." Jenkins tipped his hat slightly
"Snowy Trail?" Frisked asked
"Dusk trail was an extension of snowy trail and if you can explore it to that point without the sting of exhaustion then let the crag rock be your guide." Jenkins said solemnly
"Why would you tell me if you didn't want me to go in the first place?" Frisk asked curiously
"Let's just say Snowy Trail is the worst and if it takes your breath away Dusk Trail will be ten times harder as it hasn't been maintained. If you can't get through that trail to the point of the crag without ever fiber of your being burning for oxygen then do yourself the favor by resting and leaving the way you came." Jenkins said sourly
The excitement hit Frisk and they found themselves determined to at least see the Crag Rock if they wouldn't be able to make the hike to the top of the mountain.
Folding up the Map and shoving it in their pocket Frisk hopped into their car and made way for the mountain.
Frisk found an old campground and a not so frequented ranger station. That screamed risky but Frisk was filled with determination to see this through.
Setting up a base camp and packing essentials and emergency kits Frisk set out to find the Dusk Trail.
"It's so funny… I feel like I was supposed to make my way here. Like I'm expected company." Frisk said as they gathered the wits and marched forward towards the first open trail that would lead to Snowy Trail and hopefully have what it takes to endure the Dusk Trail.
About Halfway into the sign marked Snowy Trail Frisk was breathing heavily. It was tough but not as tough as the feeling Frisk had to get through it.
Every step seemed guided and focused.
They glanced at the scenery around them and realized how far they have come but also that the sun was starting to set. It was still morning when they had set up camp and they had blazed through the trail faster than they had expected.
As Frisk was pondering the situation of going back to base camp or to continue on they found it.
The Crag Rock that was formed by rain to look pointed towards a place in the trees.
Frisk looked more where the crag pointed until they found what looked to be signs of a once used old trail.
"Dusk Trail! I found it!" Frisk nearly squealed with glee. The fact that Frisk had more potential energy from the sheer determination to get to this point allowed them the argument to continue on.
After awhile of continuing on Dusk Trail Frisk realized the hardships Jenkins had the foresight to tell them.
Some of the trail was washed away or mudslide boulders blocked the path entirely too where there was no choice but to go over or find another way around. Frisk only glowed in excitement knowing the end of this journey would be worth it.
By nightfall Frisk had their flashlight and still going strong only to rest for a few minutes at time.
Frisk found themselves in a predicament though because they finally found themselves at the end of the trail. No other light but the flashlight as clouds had gathered and blocked the night sky at this point. Frisk got on top of a nearby boulder to see around with the flashlight better there seemed to be an alcove below. As Frisk started down they tripped over their shoelace that had come undone and their flashlight went sailing down.
Desperate to get to the light the shoe was ignored and they ran after the rolling flashlight towards to alcove.
As they approached and the flashlight came to a stop in front of the cave hidden beneath the alcove. The accursed shoelace once again made them stumble forward going by the flashlight and into the darkness.
Frisk wide eyed and scared at the feeling of nothing below their stumbling feet remembered the rumor of the bottomless pit at the top of the mountain.
The falling sensation of a long fall was terrifying enough but the thoughts that came with it made everything far much worse.
Some time passed and Frisk hit bottom passing out immediately.
When Frisk came to everything ached. They were scratched up pretty bad and badly bruised. Luckily a dead patch of growth seemed to have cushioned a major part of the blow as nothing seemed broken. Frisk gingerly tested out walking after managing to stand up it hurt like hell but they managed.
Taking a look around sunlight managed to filter a little bit onto the growth that seemed like a dead garden of flowers with some trash and shining a little light into the area.
"Are you okay?" Came a soft spoken voice that made Frisk nearly jump out of their skin.
Frisk looked around but couldn't see anyone.
"Hello? Who's there?" Frisk called
"I'm down here!" The voice cried showing a little more confidence.
Frisk looked to see a tattered golden flower that had a face. As their eyes began to widen the flower quickly at what was being witnessed the flower tried to calm the situation.
"It's okay! I'm not going to hurt you! Please don't scream it could cause her to show up and then we will both be in trouble!" The Flower motioned with its leaves to keep it the noise down.
"A talking flower?" Frisk said stunned
"Believe me there's more to freak out about than just a talking flower down here." The flower said bowing its head sadly.
That's when a word echoed in Frisks mind 'Monsters'
"My name is Flowey by the way, Flowey the Flower. It helps knowing with whom you are speaking with rather than what right?" Flowey said trying to smile
"I'm Frisk and …" Frisk started to greet
"You're a human… I know… I hate for this to sound rude but you really shouldn't be here. This place is terrible especially for humans." Flowey whimpered
"Monsters?" Frisk questioned
"Yes very real and very deadly monsters reside here. They even catch wind that another human has come they will rip out your soul as they dismember you alive. Believe me they aren't to be reasoned with." Flowey said using his leaves to sob into
"Can you help me?" Frisk asked
"I can't help you I'm just a flower. I don't have any powers to protect you and honestly I would end up in your way." Flowey trailed off sadly
"Please Flowey, You seem to know more than I do about this place and really a guide is better than going alone." Frisk smiled at the surprised flower.
"Well I guess I could help you after all I don't want anyone else to die… I don't think I can keep up with you though perhaps you could carry me?" Flowey asked.
Frisk looked around and found an old boot in the overgrowth that they landed on and helped uproot Flowey and placed him gently into it.
"Thanks Flowey I know you will be a big help and a great friend to have." Frisk smiled at the blushing flower.
"F-Friend?" Flowey's eyes were wide
Frisk merely nodded.
"I-I've N-Never had a friend… Y-Yes we will do great together and I promise to do my best to keep you safe!" Flowey shouted in confidence.
"Now it's not wise to make promises you can't keep." Came a stern feminine voice from the shadows.
Both Frisk and Flowey stiffened and glanced where the voice came from.
"Now come to me my child I can surely offer you better company than that miserable flower." Said what appeared to be a goat woman with a reddish tint to her eyes and dark clothing.
"That's Toriel, The guardian of the ruins. Do not trust her Frisk." Flowey whispered harshly
"T-Toriel?" Frisk repeated
"Come with me now child and I shall see to your wounds. They are so fresh and wet with blood." Toriel leered and it made both of them shiver.
Frisk was frightened by her mannerisms but deep down something told her to go along with Toriel.
"Okay but can I bring my new friend with me?" Frisk managed to squeak out kindly
"May I?" Toriel demanded.
"OH! I'm so sorry! May I bring my new friend with me please?" Frisk quickly rephrased
"That's more like it. Well I don't see why not but alas I don't see why anyone would be friends with a flower." Toriel said turning as you followed behind her.
She suddenly chuckled catching them both off guard.
"I've always wanted to be a teacher." She said almost begrudgingly
Flowey looked confused but Frisk smiled back at him. Something deep down inside Frisk told them that they needed to be here and the feeling had never left.
Perhaps this was destiny.
***End of Chapter***
A/N I apologize for the filler in the beginning! Just wanted a little more background for Frisk as this Frisk is not a child.
