Prologue
Note this is just after the king's children death. Alphys is a teen working with Gaster.
Gaster speaks in wingdings and few people can understand him. This includes Alphys, Asgore and a few others.
Alphys was checking the machines to make sure they were properly functioning when something caught her eye. One machine seemed to be more active than normal, a light above it was flashing, indicating that something new has been detected as the data skyrocketed. Rushing over to the machinery she gasped at the results "Ohhhh n-nooo," before dashing over to the other side of the room where Gaster's lab is. Knocking loudly she called out to the man inside "Dr. G-gaster a human soul has been detected in the ruins."
Gaster walked to the door and opened it slightly, "Yes what is it Alp…" Looking up at the restless machine his eyes widened as he realized what was happening.
"W-what do we do? This is the first time we got these readings," Alphys panicked as Gaster pushed her aside to observe the machines results.
"Interesting, go inform the royal guards, I will inform the king," grabbing a lab coat the scientist rushed off to the palace. Left behind, Alphys watched as Gaster walked off. The door behind her grabbing her attention as its hinges creaked. Turning around the young intern caught sight of bones scattered on a metal table. Much to her distaste the door closed the last of its gap and clicked back into place, leaving the young scientist's curiosity unsatisfied. Maybe she'll ask Dr. Gaster next time.
The king was where he always was, at his throne…alone. Ever since his wife left he has started to plant golden flowers, to distract himself of his children's deaths. As Gaster approached he could hear the kings hums echo throughout the halls, it wasn't joyful as it was before but rather a sad tune used to mourn a monster's loss and death. "Your majesty may I have a word with you?" Gaster asked as he paused before the lonely king.
"Yes what is it Dr. Gaster?" replied Asgore, placing down his watering can before turning to face the royal scientist.
"A…human soul has been detected in the ruins," Gaster approached carefully doing his best not to bring up any unnecessary memories within the king.
"Has the royal guard been informed upon this matter?"
"They are being informed as we speak." At this statement Asgore's face dropped slightly, knowing that this child would soon perish. Taking the king's pause as a sign to continue Gaster quickly proposed his own request "I would like to request permission to use the human soul in one of my experiments."
"What need do you have for the soul?" Asgore questioned, eyebrow raising in intrigue.
"I would like to transfer part of the soul to an artificial body that I've created in hopes that the soul will be able to grow. This way we will be able to leave the underground faster, and…no more human children will have to perish, my king."
Asgore raised his head and it felt like a huge weight has been lifted off his shoulders.
"I'll give you permission," he granted ending the conversation as he picked up the watering can and continued onto his previous task.
"Thank you sire, I will be sure not to disappoint," Gaster promised, turning to take his leave. As he strode down the empty halls he could hear the king hum a more upbeat tune.
*A few days ago in the ruins.*
"Call me mom, my child," Toriel suggested to a young girl who adorned a small ribbon neatly tied around the end of her braid.
"Ok mom," she replied with a huge smile as she jumped up to hug the loving monster. She was happy to have a home, if she's patient enough she might be able to see her old home again.
A few days have gone by and the young girl was now allowed to wander the ruins. Mom had told her to find a place far from the house to go and play at, she had noticed that mom had looked worried though she didn't know why. The monsters there were actually pretty friendly as she would sit through and listen to what they had to say, even when she didn't understand what they were saying.
Today she has gone to where her favorite spot is in the ruins, a small lookout point where she is able to see the vast sights of the underground. Every now and then a monster would come by and sit with her, she enjoyed the company. In the room behind her she could hear footsteps in the distance, they were different compared to the monsters from around here. Their footsteps were loud and synchronized, the constant clangs of what she believed was metal sounding odd for any of the usual monsters that she's met during her stay here. Turning around she believed that a good introduction would leave the best impression just as mom had once told her. She heard three sets of footsteps 'It's not one friend, it's multiple friends' she thought, smiling at the idea. The figures entered the area that she was in, there were three of them. She observes that one of them was tall with armor just like a knight, the other two looking like cute dogs besides the burn marks scattered across their fluffy fur. "Hi! My name is Konki and I'm 6 years old," she greeted with her best smile.
One of the doggies turned to the knight with a questioning gaze "Is this the human?"
"Yes it is, I'll kill it if things gets messy, don't hesitate to step in," the knights deep and masculine voice agreed.
The small girl tilted her head in confusion as she echoed the mentioned word, "kill?" She has never heard of such a word though she remembered mom mentioning that it was a bad thing, which was confusing to her since these three seemed to be so nice.
"It's becoming hostile, we should end it," the other dog stood on alert ears back and hand instinctively on his weapon, getting ready to attack.
"Settle down we don't want to startle it," the knight responded. "Just let me deal with it," he announced, removing his helmet to reveal a face that resembles a fish and kneeling next to the young child. "You remind me of my daughter," he commented to the girl almost absentmindedly. The two dogs looked at each other in confusion, unsure as to what the knight was getting at. "She is just as cute as you," at the compliment the girl giggled cheerfully, grateful for the kind words. "Do you know what happened to her mom?" he asked, voice almost playful despite his deadpanned look.
"What?" she asked.
"A human killed her in battle," he replied calmly, pulling away from Konki to stand tall, the girl left in a confused state as she processed the given information. Summoning a spear he struck, stabbing Konki without a second thought, the weapon knocking the small girl off her own feet and skewering her against the smooth stone beneath her. Konki's eyes widened in shock, the pain in her chest was unbearable, though despite the agony she was able to reach into her pocket and grab her toy knife to try and protect herself from the merciless attacks. Unfortunately for her another spear pierced her outstretched hand, forcibly releasing the toy and drawing out a pained cry, tears prickling her eyes as she was left to stare up at the cold eyes of the armored monster. "She died protecting our daughter and you humans took my wife away from us," he growled darkly, scowling at the dying girl, hands gripping tightly to the glowing spears in her chest.
Tears trailed down her cheeks, mingling with the blood that has slowly started to pool beneath her, mouth opening and shutting as if she had no words to say other than an apology with barely enough energy "I…a-am…so…sorry…for your loss," her lungs finally giving out as her eyes rolled to the back of her skull, her body growing limp, as a light blue soul emerging from her chest.
"Nice work sir," one of the dogs praised, eyes watching the dead body for any more signs of life. The man stood up and dispersed the spears from the girl's body.
Looking over to the dogs he gestured to Konki's body besides his feet "Hand me the container and you clean up this mess." The man trapped the soul within the container and made his way back to the castle. On that day the door to the ruins was sealed off from those in the underground by a strong magic; three more humans soon met the same fate.
