CHAPTER 1

Laughter bounced off the cavern walls in a chorus of glee, echoing faintly into the distance.

"LOOK OUT BEEELLLllllooooowwwwwwwwww…..!"

The two children howled and cheered loudly as they shot down the hill at top speed, holding onto the sled for dear life. Frisk, who was busy manning the reigns, pulled the rope this way and that, causing the sled to zig zag sporadically down the hillside. The two children had been partaking in snow related activities for the past few hours and were red faced and numb from the cold, but that didn't matter, they were having far too much fun to notice.

Suddenly, the sled shuddered violently as they careened over a large branch half buried beneath the snow, causing it to nose dive and send its passengers flying.

Frisk's attempts to stay aboard were futile as the rope was wrench from their grasp. Monster Kid, without the use of hands to slow his momentum, went sailing overhead with a cry of surprise before crash landing several meters away.

The two children lay face down in the snow in varying levels of disarray for a few seconds before emerging in a fit of giggles. "That. Was. Awesome!" Cried the monster, kicking his feet excitedly. "Let's do it again!"

Frisk jumped to their feet and stumbled over to their companion, stifling laughter as they went. Grasping them by the scruff of their neck, Frisk yanked Monster Kid to his feet and quickly brushed off the snow covering his head and shoulders. Nodding encouragingly, the human scooped up the reigns to their sled and began the trek back up the hill, the monster following quickly behind.

As their laughs died down, the two settled into a comfortable silence.

Frisk had missed this.

"Ya know-" Monster Kid began. "This has been really fun. It stinks that you have to work all the time…"

The child trailed off, a look of sadness flashing briefly across his face. Frisk smiled sadly and nodded. "Yeah, I've really missed you guys too, but I'll come back as often as I can." Monster Ambassador had turned out to be an extremely time consuming position as it turned out, especially as of late. It had been several months since monsters had achieved their freedom, and their presence was now known throughout the world. In the beginning there had been panic and shock, followed by confusion and fear. It had taken nearly all of Frisk's time to quell the heightened emotions on both sides and prevent another war. Fortunately, with the help of Asgore and Toriel, the three had worked tirelessly with leaders and political figures in order to calm the masses. Others had helped, of course, but the job seemed to be never ending.

Monster kid smiled sheepishly. "G-good! Now come on, I'll race you to the top!" And with that, the child darted up the hill, snow spraying in his wake. Frisk grinned mischievously and took off after him, dragging the sled along with them…

Before slowing to a sudden stop.

"MK? What's wrong?" The monster had frozen in place, giving Frisk the chance to catch up to him in a few strides. Coming up beside the yellow clad child, Frisk got a look at his expression and paled.

He looked…petrified.

Following his gaze, the human child peered into the distance before spying something on the hilltop opposite of them, closer to the ruins.

A figure.

It was hard to make out, but from what Frisk could tell, it seemed to be a person wrapped in heavy layers to shield them from Snowdin's bitter cold.

A period of silence hung in the air before Frisk interjected curiously. "Who's that?" Monster Kid didn't answer. Instead, he took a hesitant step backwards. "MK?"

"Don't you feel that?" He responded shakily.

"Feel what?"

The monster looked as though Frisk had lost their mind. "Something's not right. That person- I don't know, they just feel…WRONG. You're telling me you don't feel that?"

Frisk looked back and forth between the two. Pressing their lips together in a tight line, they shrugged diplomatically. "It's probably a human wanting to check out the underground or meet some monsters. You know how it goes." Frisk tried to reassure him. "Who knows, they could end up being friendly." Turning from their companion, the human resumed their climb in the direction of the newcomer, lifting their arms in a way of greeting. "HELLLLOOOOO!" Frisk called. "WHAT BRINGS Y-"

"ARE YOU CRAZY!?" Monster Kid crashed into Frisk head first, sending the two sprawling to the ground. Normally such surprise attacks were exchanged between the two in a good natured fashion, but this had a sense of urgency that made the brunette bristle.

"If you're that concerned, then how about you stay here and I'll go see what they want?"

Monster Kid huffed indignantly. "No way! I can't let my friend face danger alone!"

Frisk considered a moment. "Well, they might be intimidated by meeting a monster for the first time. So what if I go introduce myself and then bring him over to meet you?" Perhaps the reason the stranger had yet to approach the two meant they anticipated danger? Frisk was use to all kinds of responses when it came to meeting monsters for the first time, and they had grown quite apt to making others feel at ease during introductions.

This did little to convince the monster. "I dunno….maybe we should head back?"

"And bring even more monsters? That's probably a bad idea." The last thing they needed was to give the poor guy a heart attack. "Don't worry, I'm human." Frisk reasoned confidently. "Even if they're intimidated by you guys, they shouldn't have a problem with me. And once they get to know how great you all are, they'll see there's nothing to fear!"

Monster Kid looked perplexed, but didn't seem to have a comeback to Frisk's logic. After a brief period of mulling over the idea, the monster finally relented. "Ok, I'll hang back. Just wave me over when you're ready, or call if you need help." He puffed out his chest and gave a triumphant grin. "For I, the GREAT MONSTER KID, will come and save you! Nyhehehe!" His laughed cracked and faded as he spared another side glance at the figure, his anxiety returning once more.

Frisk smiled warmly at their friend, they truly were fortunate to have such caring people in their life. They nodded, before turning and heading off in the direction of the figure, leaving the sled and monster behind.

Traversing the snowy plane took several minutes of plowing through the knee deep snow. Frisk had dressed warmly for the occasion, but the dampness clinging to their clothes significantly slowed their pace.

As they drew closer, Frisk resumed their friendly waving. "Hello! Welcome to the underground! Have you been here…be…fore?" Frisk trailed off. Upon closer inspection, the figure was most defiantly a human male. The man was tall and disheveled, shrouded in black from head to toe. But what had caused Frisk to slow to a halt was not the man's large build or odd choice of dress.

It was his eyes.

Pure, unadulterated distain blazed in the golden eyes of the man looming before Frisk. Gray hair and stubble, along with deep wrinkles under his eyes and mouth indicated the man had lived a long and difficult life. A large cloak and cowl covered the majority of his facial features, however his narrow eyes reflected a lifetime of bitterness.

Frisk slowly lowered their arm, the cheerfulness draining from their body in an instant. The child had never dreamed that so much anger could be conveyed with just a single look; the very air around the man was thick with bloodlust. Against all odds, it was possible his malice rivaled that of Chara's.

The man looked down at something in his gloved hand, studying it contemplatively, before slipping it into his pocket. Afterwards, the stranger turned back to Frisk and smiled, revealing dull and crooked teeth.

The two stood facing each other in perfect silence, several yards remaining between them. "So." The dark figure began. "You're…the monster ambassador." Not a question. A Statement. Frisk's eyes traveled down to the man's belt, where they saw a beautifully crafted and frighteningly cruel looking dagger. The realization must have shown in their eyes, for the man reached for the hilt, swiftly unsheathing the blade and holding it out. "You like it?"

Frisk didn't answer.

"You want it?"

Frisk edged backwards.

The man chuckled and tilted his head to the side, running his fingertip along the edge of the blade. "Well then…you can have it."

Run.

The instinct was sudden and powerful, and before they even realized they were moving, Frisk had spun around and was dashing madly through the snow.

The stranger followed without hesitation, maintaining a dogged but measured pace. Running from him made Frisk feel like a wounded animal fleeing from a savage predator. The man's pursuit sent a rush of adrenaline through the human child, fueling their frantic retreat.

"FRISK?!" Monster Kid called from somewhere in the distance.

"RUN! RUN AWAY!" They screamed in response, too panicked to pinpoint their friend's exact location. "GET AWAY FROM HIM! RUN BACK TO THE SURFACE!" Frisk registered some sort of response in return, but was unable to make it out over the sound of their own rapid breathing and frantic heartbeat.

Frisk gave an internal cry of dismay when they realized they were heading deeper into the forest instead of toward the exit. Unfortunately, the man's larger strides and rapid pace made it impossible for the 10 year old to loop back around to the ruins without getting caught. So Frisk persevered, sprinting as fast as their legs would carry them.

The head start was helpful, but would not last long at the rate the two were going. What was knee deep snow to Frisk was only up to the stranger's shins, allowing him to more easily navigate the snowy terrain. He was going to catch up at this rate. Terror surged through Frisk's whole body, driving them onward.

And that's when they saw it. A glimpse of bright red at the top of the hill.

Without a second thought, Frisk threw themselves into the sled and barreled down the hill at a breakneck pace. The wind, which had been invigorating only a few minutes ago, tore angrily at their jacket and whistled ominously. But the getaway had been effective, creating a large gap between Frisk and their pursuer. Feeling a momentary surge of triumph, Frisk leaped from the now stationary sled and bolted deeper into the forest, intent on losing the man in the woods.

The chase dragged on and on.

I don't understand! Frisk thought despairingly. What does this guy want? It would have made sense for the human to lash out at the monster (unfortunately this was a common reaction), but the man did not seem even vaguely interested in the monster child and had instead pursued Frisk. They'd even identified them by their official title.

It had been at least fifteen minutes since they'd last caught sight of their pursuer. While the footprints Frisk left if the snow prevented them from effectively losing him, perhaps they had managed to out distance him? Stopping was out of the question, but perhaps they had enough time to risk a quick phone call…

And then, Frisk felt it. The feeling of "wrongness" that Monster Kid had described, crashing over them like a tsunami.

An ominous hiss and crackling filled the air, similar to the sound of electricity raging freely through a conductor. The space around them began to vibrate, distorting the image before Frisk's eyes. Never had they been filled with so much terror as they spared a quick glance over their shoulder.

The tree just to the child's left exploded in a burst of splinters, cracking so loud it sounded as though the underground itself was collapsing. A sharp and sudden pain flared through Frisk's shoulder and hip, sending them sprawling to the ground.

They clutched their side instinctively. Jagged bits of wood and bark were embedded in their upper arm and thigh. The site was so grizzly, Frisk had to look away to keep from becoming sick. Blood seeped between their fingers as well as down their face from a gash on their cheek. Disoriented, the human managed to regain their footing and staggered forward. To remain still was death; they had to keep moving.

They had to stay determined.
