Summary
It's well past midnight, and Sans still hasn't contacted him. Papyrus, while searching every nook and cranny in Snowdin, makes another call, his phone rings once, twice, thrice... and nobody picks up. Just what in God's name could possibly be holding up his brother during this night, and why didn't he bother to tell him anything about it, after he had explicitly promised to...?
Then, to his surprise, a familiar golden corolla appears in front of him - but not for the reasons he'd hope.
"Papyrus! Hurry! Your brother's in big trouble!"

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.

Summary
Life isn’t fair, case in point, you didn’t expect to be trudging through the snow to the corner store to pick up some much needed, over priced, feminine hygiene products while trying not to bleed all over yourself all because you failed to remember to pick them up with your normal shopping. That’s the thing, no one ever said life was meant to be fair did they?
~*~
Promises were just words, promises of home, safety, love. Only ever worth something if the person kept those words close to their soul. That was something he learned pretty damn quick. Built for love, to be a friend, a companion, tossed into the rings to be a fighter, something he was never meant to be. The only promise he knew he could trust were the few he made to himself, the promise to never fall for the sweet lies of a pretty face again.
~*~
What happens when two souls who honestly need each other, don’t know how to open up and trust? Can love, trust, and home be found when the world has proven that trust is a dangerous thing? Can they get over the hurt that this unfair world has piled on them? Open up to each other and maybe, just maybe find the home they both need?Series

Summary
The strong nuclear force is defined as the strongest of the four fundamental forces of nature. It is the force that binds protons to neutrons inside of an atomic nucleus. On the quantum level, it also binds quarks of similar charge and direction together in order to form protons and neutrons.
The summer after her graduation from undergrad with dual degrees in biotechnology and theoretical physics, the world around Vera Jefferson changed. An entire new race of people poured out of Mt. Ebott, the namesake for her university. The monsters that now populated the militarized zone around the campus and base of the mountain were strange, but kind. Having made quick friends with the sarcastic bartender/owner of the restaurant across the back alley from her apartment, it seemed as though her world had changed for the better.
Once she starts the first semester of her PhD, she realizes just how true that is when she meets some of the other monsters around campus. Life may not be easy, but with the help of the people she went through undergrad with and her new friends from underground, she feels for the first time that she just might make it through.

Summary
The leader of the human province and head mage, Cadoc, has no qualms in letting anyone willing to listen know that his third daughter—an unassuming girl with a deep blue Soul—has the most powerful magic known to mankind. She's able to perform feats that would make the entire monster kingdom tremble in fear. She may even have enough magical prowess to tip the scales of power between the already tentatively peaceful neighbors.
Reluctant to violence, but hand forced with the protection of his recently unearthed populous, King Asgore levels the humans with an offer. Hand over this Blue mage to be paired with his Son, in a show of unity between their nations. Eager to breach the tall walls of their secret kingdom for information, Cadoc agrees.
Unbeknownst to all, there's a third party at play, who's been intently watching the Head Mage's daughter as she spends her time in the meadow between their lands. She's nothing like everyone says she is... and soon he finds he's fallen for her—hard.
When the Prince agrees to switch places with him for the courtship ritual, her secret admirer will have to win her heart, and Soul, sight unseen. But can he keep pretending he's someone he's not?

Summary
“Not so fun being stuck in some loop right? Trying to fight to protect what ya got, not getting a choice in it. If I had the choice I wouldn't remember either.” The words oddly felt comforting. Link let out a slow breath, closing his eyes for a brief moment.
He didn't feel alone for the first time in a long time.
And that?
That was terrifying.
“To be honest, I kinda gave up a while ago. Just sat back and let the chaos go on, felt like nothing I did mattered anymore. Everything would just be reset anyways. Stopped caring what happened, that was until you showed up.” The skeleton’s eyes bore back into the Hylian.

Summary
The real world can be a cruel place.
There is no Dark World. No Lightners. No Darkners. No prophecy to set forth a chain of events to whisk away tears and make everything right. No chain of coincidence to magically and miraculously mend broken bonds and build friendships anew.
In the Real World, there is only Kris—lifelong loser and social outcast. Amidst a broken home, an unrequited childhood crush, and the myriad other struggles of adolescence, they want nothing more than to live a regular life—to be normal—to blend in.
Or: Kris weathers the decadence and melodrama of modern suburbia.
Updated weekly.

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.
