Long ago, two races ruled over the earth: Humans and Monsters. One day, war broke out between the two races. After a long fought battle, humans were victorious. They sealed the Monsters underground with a magic spell. Legends would say those who climb the mountain never return. This had been true for many years after they were sealed.

Vanished without a trace… Orario the Labyrinth City a place where Gods and Adventurers alike flocked to the city with aspirations of grandeur. But one person was different. They never wished for glory or wealth. But rather they held a desired to be a Hero like the stories of old and they are Determined to see this through. How would desire intertwine the fates of these two worlds. Will they change for the better? Will they change for the worse? Only time will tell. But there is one thing to be sure of. This tale will be very, very interesting…

Summary
Everyone had found their breaking point at that balcony. A clash of ideals, unfinished business and finally an end to Clover's long journey. Or it would have been, like it usually was. No longer in shape to make any rash decisions, their body battered and bruised, Clover finds their life falling into the hands of another.
Hiding a child which the entire Underground wanted to see dead was one thing. Treating a child of a different species after they had sustained mortal injuries was another.
Martlet had made a promise, and she intended to keep it...even if she wasn't particularly good at keeping those. But this time was different.
...Why did she care so much? Martlet had just met Clover, right? However none of that mattered now. The only thing that did was getting Clover to safety. Everything else could wait.

Summary
Reality and Fiction. One that resides in our world and the other that we create. Now, what if I tell you that there’s a universe where two exist in the same world? In a world where both real people and fictional characters live on the same planet, what do you think would happen? Would it be peace, chaos, or something much deeper? Let’s take a look at one of them to see how they live in such a world like this and find out for ourselves!

A Flower’s Love by AnonOliver

Summary
Flowers aren’t really meant to have morals. Heck, flowers aren’t really meant to have a mind. Even in a world where your father was a giant goat, your neighbour was a deer, and that weird parrot from the library has blood on his hands, it’s still rare to think that a dormant, motionless flower could think, could feel, could love, could remember.
But life always finds a way. A dark, darker, yet darker way that I can trust you’re all at least slightly familiar with. And if you’d just care to imagine with me for a moment, you can see how our tale can come to be. A story about a flower who called his fears his ‘integrity’.
———
Blue reveals a Secret to Yellow, and Yellow makes him feel safe.

Summary
Congratulations clover! You’ve finished your pacifist route and Flowey doesn’t reset.
Huzzah!
Do you really think that’s the end of floral problems in your life that involve messing with your memory and death?
Honestly, you should know better than that! Or maybe you don’t. I don’t blame you.
(The concept of the human souls are inspired by certain events in deltarune chapter five but I’ve still tried to maintain seperate views and keep some consistency between what we know from uty so while I wouldn’t say it’s spoilers per se this is your warning)

Summary
6 beings, each unalike in many ways, are teleported into a white void somehow and somewhere in the Undertale Multiverse. They are unsure how and why they are here, but one thing is for certain, they don’t plan on staying in the void for a second longer. But as little as time passes, they soon realize that they have…changed.
For the better.
And the worse.
So, shall you see how this plays out for them?
Note: Hey y’all! I’ve been rewriting a lot of these chapters lately, so things may change during and after the completion of the entire story. First work, so rushing around with how this works and all. Thanks for your patience and have fun reading!!!

Summary
In Woventale, the Underground is a patchwork of strange cities and altered destinies, where familiar faces walk unfamiliar paths. Across the stitched landscapes of Snowfall, Sea Shore, Smokestack, and the Forest Ruins, lives intersect in quiet, calm, or sometimes dangerous, and unexpected ways.
This is the world woven by 'Watchers'. Like you. So why not stay awhile, and listen?
This - is not a grand story. This is a collection of short stories, moments, scenes and encounters.
