Kingdomtale part 2 (pacifist series) by melodic_melodies
Fandoms: Undertale (Video Game)
12 Jun 2025
Tags
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
Clover had done everything he’d set out to do. He had found out what became of the Fallen Children, helped his new friends resolve their issues, or at least put them on the road to doing so, and now all that was left to do was to finish his journey…and face the destiny that awaited him at the end of the road he had chosen.
But what if, instead of immediately hopping right to giving up his soul, he took the time to stop and weigh all his options? Along with the pros and cons of each? And in doing so, what if he realised there was still one more loose end to tie up? Perhaps even one more soul that needed saving?
It's not like this one deviation from the script will change all that much, right?
….Right?

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.
