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.

Summary
Shattered had ruled over his multiverse for ages, having long since plunged the world into a neverending pool of toxic positivity that fed him well.
But one day, he was betrayed-overthrown and banished to a different multiverse, never to return. Well, that was fine! He could just make a new empire! He-
Wait, he just..did he just stab his counterpart-
Oh. Oh, shoot, he'd just killed this world's Dream.
These characters are not mine!

Summary
The barrier has been destroyed. After an era of isolation underground, monsters are free once again. They long for a peaceful union with humanity, but they aren’t sure if humans are ready to welcome them. To prevent history from repeating itself, the monsters decide to study human society, hoping to understand whether people are open-minded enough to accept those who once lived underground. Thanks to Alphys’s technology, a small group of monsters - guided by Frisk - secretly infiltrates the surface to carry out this mission.
Your life feels like it has reached a point of no return. You left Europe hoping for a new beginning. However, your hopes for salvation don't seem to be meeting your expectations, not here in California. Still, you refuse to go back. You believe that your situation will improve over time. With this mindset, you adapt to your new circumstances, suppressing your depression as best you can, accepting a job you hate by telling yourself it's only the beginning. After all, you have to start somewhere, right?

Summary
A long time ago... humans and monsters lived in harmony. Until war broke between the two races.
The humans were victorious and sealed monsterkind deep underground with a powerful spell, that could only be broken with the power of seven human souls.
This was the tale of Mt. Ebott, and the tale trascended into legend. Those who climbed the mountain, weren't seen again.
And so, begins the tale of the fifth human soul to fall into the land of legend, to fall... into the Underground.
This is the tale of the Purple Soul... Sunny Suzuki.

Summary
The District of Mount Ebott, or the DoME, for short. The heart of the metropolis, the city, the only territory within the states with the highest monster population for the past few decades. It was only a strike of circumstance for this blighted girl from the Midwest to find herself thrust in the core of it all, such not without three souls she'd do anything to protect underneath her roof.
Monsters–mobsters–mafiamen.
Who knew she'd end up as the most relevant piece of the puzzle for the tensions between the Crowns and the Canines. Such a poor, indiscreet woman with no more value than the stick up her ass surely couldn't attract too much attention from the wrong crowd.
Well, whatever it is they say, keep your hide close, and your enemies closer.

Summary
Humans are afraid of the unknown. The solution to this problem? Welllll uhh... it's obviously to shove the problem in area 51 one and then build a school the size of America's need for healthcare since copies of the problem JUST. WON'T. STOP. SPAWNING. So follow the story of the troublemakers of wing 4-B I guess..
or
I shoved a bunch of random characters in area 51 and built a massive school on top of it because why not at this point. And characters are very ooc.
(Not that much knowledge of the characters is needed)

Summary
A series of dialogue. A set of numbers.
After a slew of countless RESETs, Flowey is driven out of sheer desperation to commit a taboo he has never tried before.
While Papyrus vows to try to help and understand his friend…the truth comes to light when Flowey expresses that he will never feel the same way any other monster can.
Flowey comes up with his own solution for this, and it's not a pleasant one. But apparently that's okay since consequences are usually beyond Flowey.
…But now things are suddenly escalating beyond his control. Not that Papyrus ever had any control to begin with.
Flowey, the Human…is who is in control really the point?
…So then…what's left?
Only the Pretty Poppy can decide now.
