Kingdomtale part 2 (pacifist series) old by melodic_melodies

Summary
The second part to Kingdomtale. Will our protagonist be able to make friends with everyone and stop the second war? We’ll just have to find out!
Warning: may contain mentions of abuse, violence, blood, dust, death, depression, attempted suicide, cursing, romance, weird/Toby logic and ships. If any of these bother you then probably just continue to not read this series, otherwise please enjoy yourself. This takes place after part 1 and humanity’s creed. Again our protagonist Frisk is only referred to as a girl or she/her when it’s the humans talking due to the time setting and because of the morals discussed in humanity’s creed. Otherwise they are referred to as they/them (nonbinary pronouns. Or whatever other nicknames I mentioned in part 1). All oc’s are owned by me, other characters are owned by Toby Fox.

Summary
No one asked for this outcome.
No one wanted to be trapped, separated from the world for fourteen years.
No one in the situation believed it would last forever.
So, what do you do when you're aware of the timer above you? You make the best of it, or you run.
TLDR: the Amalgamate Experience from the POV of its luckiest members: Kanako, Posey, and Doctor Alphys.

Summary
Hush now, little one. I have a story to tell. A story about humans and monsters.
Frisk Estrella lived on the surface, and was just one face in the crowd of thousands within the large city. Buckling under the pressure on his home life and internal forces preying at his mind, the last think Frisk wanted was to end up being on the run from the cops. Unfortunately, some don't get a happy life.
After a confrontation leads the boy wanted for murder, Frisk ends up in the bottom of Mount Ebott, where he discovers a civilization of mongers just below his feet. To anyone, they would be horrified, and would try and venture through to leave.Frisk however, finds himself growing familiar with this place of monsters, and soon enough, thinks about staying. But as he makes friends and allies, hundreds of years of history begin to rear their heads as Frisk must confront enemies that could threaten not just the Underground, or humanity, but the very nature of existence as well.
In order to save his friends, and himself, Frisk must have DETERMINATION to survive.

You watch them suggest names and argue with each other as you stand there dutifully like a newly-adopted dog. Rus sidles up close to you and looms over you like a hanging specter. His smile does not look friendly.
“How about..Snowy,” He suggests, his grin widening at the twitching grimace on your face.

Summary
After everything went to black, Clover asked themselfs if this was how death was. If they had anyone to wonder.
It was too dark to see, too silent to hear, too empty to even think about it. A little more and they could feel the cold, hard glass of the container they're inside, trapped for who knows how long. It could be hours, it could be days, or it could be centuries.
It feels like centuries, until it doesn't.
And a dark, misterious ceiling with a light too bright welcomes them. It's not a warm welcome.

Summary
It has been 5 years since monsters were freed from Mt. Ebbot by the human Frisk. Its also been three years since The Anomaly incident of 20XX.
In order to combat the surge of misplaced monsters, and to encourage the unification between humans (and mages) and monsters, an Ebbot based program was launched. LIM, Living in Mutuality Agreement; or its little-known counterpart, Live In Mage Act.
The goal, have mages live with the newly displaced monsters, ensuring peace, and slowly introducing the newly appeared monsters into society.
The catch, your one of them, and no one can know you're a mage. -

Summary
Knocking on the lab's door didn't lead to anything. Not that Sans expected it to; if Alphys wanted to be found, she would've answered his calls. But if she wasn't in her lab, wasn't in the castle in New Home, nor at the dump in Waterfall, that meant she really, truly didn't want people finding her. And that...made him uneasy, to say the least.
Well. There was always one other, last place she could be in. The other laboratory.
With a defeated sigh, Sans took a quick shortcut into the standard lab. He stared at the elevator that would take him down; it really was the only place Alphys would be. And even though he doubted he could be of much help with whatever problem she was having, maybe she'd at least appreciate the company.
So, Sans headed down into the darkness.
