The Judgment Hall...
Sunlight was pouring into the judgment hall through the tall windows, and at the same time, there was a dripping sound. In fact, that was seemingly the only sound that was breaking through the complete silence...unless someone were to get closer to the source of the sound. If one were to do so, they would begin to hear, not something, but someone. The sound one would be hearing was the quiet sobbing of a young child. This young child was a boss monster named Asriel Dreemurr, the son of Asgore Dreemurr the Royal Scientist, and Toriel Dreemurr, Captain of the Royal Guard. This all started when that demon disguised as a human fell into the Underground. When they first left the ruins, things didn't seem so bad. Nobody could have guessed that things would have turned out this way.
Earlier in Snowdin...
"What the... wh-why would anyone do this?!" Chara finally broke the deafening silence with, when she finally found her voice. Monsters had started to disappear and she had been asked to aid the royal guard in searching for monsters that had been reported missing... only to find piles of dust near where they had last been seen. Dogamy and Dogaressa, the lead Royal Guards, reported seeing a human slowly shambling away from the dusty remains of Snowdrake. They were both killed. After that was when Chara decided it was too dangerous to let anyone fight the so-called "human".
This is all my fault, Chara thought. I noticed how high that murderer's LV was, and I did NOTHING! I never thought I'd say this...but whatever that thing is... it's way worse than a human. And even worse nobody can beat it! I have to get back to Snowdin, and warn everybody!
But before she headed to Snowdin Town, she decided to leave a message for the human.
"So, looks like you're having fun, huh?" Chara commented dryly. The human just stared at her with a blank expression.
"Listen, I may not understand why you're doing this, but if you keep going the way you are now," Chara said as black pits replaced her eyes, "I will make your life hell."
Though they tried to hide it, Chara definitely could see an obvious flicker of terror from the human. With that Chara took a "shortcut" back to Snowdin to warn every one of the impending attack.
Later...
"Ugh! I might as well just disable the rest of these puzzles if the human isn't going to even try to solve them." Asriel grunted. He was very frustrated and slightly hurt as he walked back to his house since the human wasn't even letting him explain his puzzles.
"Hey! You! Stop! DREEMURR DUDE!" came the voice of RG 01 just ahead of Asriel. He wouldn't have even looked in RG 01's direction when he was so frustrated, but the royal guard's voice was radiating concern and fear.
"RG 01? RG 02? What's wrong?" Asriel asked. RG 01 looked surprised at Asriel's question. As if he didn't know?
"You seriously didn't hear?! There's, like, an aggressive human coming towards Snowdin! Captain Toriel, like, told us to totally evacuate everyone in Snowdin and stuff," RG 01 declared before turning to RG 02 and saying,"Right, bro?"
". . ." As usual, RG 02 stayed completely silent. This revelation, however, made Asriel take on a mortified expression. Did this mean that the human that he tried to make a good first impression on was skipping the puzzles so they could try to kill him?! Such terrifying information was almost too much for him to handle.
"I know, it's pretty scary, huh? Well, just stay chill. We'll bring you someplace safe, OK?" said RG 01. With that, he turned and walked a few paces along with RG 02, but they both stopped when Asriel wasn't following them."Well, little dude? You comin' or what?"
". . . No. Not yet. There's something REALLY important I need to take care of." Asriel said firmly. This was probably not the response the Royal Guards were expecting, and certainly not the answer they wanted to hear.
"Whatever it is it better be REALLY important, little dude." RG 01 stated flatly. What Asriel said he was going to do, was completely absurd.
"HAVE YOU ACTUALLY LOST YOUR MIND?!" RG 01 shouted, startling RG 02 and Asriel. "You, like, honestly can't be serious. The human actually totally killed every Royal Guard sent to intercept them! What makes you think YOU stand a chance?!"
Asriel inhaled and exhaled sharply, "I know how dangerous this is going to be. But I need to try." Asriel said reasserting himself.
RG 02 sighed, knowing there was no way to convince Asriel to come with them now.
"fine, just...if you even think that the human is getting near; just run...don't even think twice about it...okay?"
Asriel nodded affirmatively. "I'm the absolute deity over monsterkind! I won't die!" He declared confidently. With that Royal Guards left, albeit reluctantly, and Asriel got to work. He figured that he could die with what he was going to do, so he left a note where he knew Chara would find it. With that taken care of, he left to wait at the end of Snowdin that lead into Waterfall.
Elsewhere...
"Okay, everyone that can evacuate, do it. But if you can't, just barricade yourselves in your houses. After that, you can only expect the worst and hope for the best." This was several minutes earlier when Chara and her mother along with the rest of the royal guard were working on evacuating Snowdin. Now there was no one left in Snowdin town except for Chara and Asriel, who had decided she was going to barricade herself in. Just as she had finished up with Toriel she headed back to her and Asriel's house.
Asriel's okay, Chara was thinking to herself as she jogged back to their house, Once you go through the door, Asriel is gonna be waiting for you in the living room. However, before Chara could enter her home, she found a note taped to the door. What she read on the note, however, caused her to experience fear like she didn't even believe was possible. She didn't even have to keep reading the whole letter to know what her foolish little brother was up to. She took off running not even bothering to look back.
No, no, no, no, no, no, no, no, no, NO, NO! PLEASE NO! Chara internally screamed as she sprinted to the area that was the beginning of Waterfall. ASRIEL YOU DAMN IMBECILE! HOW COULD YOU BE SO STUPID TO THINK YOU COULD STOP THAT THING?!
Frisk had just arrived at Snowdin and was very excited to see everyone's reactions when they started slaughtering everyone out of the blue. The only problem was that there was literally only one monster in the whole town. Someone who introduced himself as "MK". Frisk was rather upset by the desertion of the town. It was so frustrating to them, that they couldn't kill any of the town dwellers, they were even half hoping someone would exit one the abandoned buildings.
BUT NOBODY CAME.
Pushing past the disappointment, Frisk moved on through the town. (Though they did find time to steal a lot of Bisicles and Cinnamon Bunnies.) After moving past what was apparently Asriel and Chara's house, Frisk entered an area covered with fog that made it impossible for them see farther than a meter or two. They stopped when they spotted the silhouette of Asriel in the mist.
"S-Stop, newcomer!" Asriel called out. This didn't really do much to deter Frisk as they ignored Asriel's command and took another step forward while smiling sadistically. It was so obvious to them that Asriel was terrified. "H-Hey, I'm t-trying to talk! Quit m-moving!" Asriel took a deep breath, trying to calm his racing heart, and continued his speech.
"I, Asriel, the Absolute GOD of Hyperdeath, have some things to say! First off, you're a freaking DOOFUS! Not only do you seem to hate my puzzles, but the way you keep wandering about with all that...m-m-monster d-dust all over you. It just seems like...like you're picking a dangerous path for your life to take. ALTHOUGH! I, the Absolute GOD of Hyperdeath, foresee a better path for you! I think everyone can be good if they just try to be! And me, I don't even really need to try at all! URA HA HA HA HA HA!" Frisk had decided they were done delaying this pathetic creature's death. "H-HEY! STOP MOVING! This is just what I mean! Newcomer! I think you just need someone there for you! You just need a friend! But don't worry! I, Asriel, will happily be your first friend! I can help you be a good person!" Frisk had run out of patience and started slowly walking towards Asriel, step by step. "You're approaching me again. Are you offering a hug of your friendship?! Yippee! My lessons are already working! I accept you with open arms!" Frisk smiled sadistically, they had Asriel right where they wanted him. The were about to punch Asriel down with their Tough Glove...
BUT SOMEBODY CAME.
Just before Frisk could kill Asriel, Chara came in from out of nowhere and slashed at them with her knife, forcing Frisk to jump back to dodge. "Sorry, mirror! Not gonna happen!" And before Asriel could say anything, Chara grabbed him by the arm and she dragged him with her through a "shortcut". And then they were just gone. Frisk wasn't too happy about Chara intervening, but they knew they would run into Chara and Asriel again. They knew.
