    Summary

    Far away and long ago, two races ruled over Earth, Humans, and Monsters. However, why is it that when all was at peace the races began to stir conflict out of nowhere?

    (F/n) has always been bad luck and to be frank, was never more than a pawn into someone else's game. When you think you've finally bested your inner demons they conquer your mind once more, caging you to the decision to either fight against your own race or fight against the family that never stopped believing in you.

    Summary

    Marrying at twenty and divorcing at twenty-two doesn't exactly leave the best image of you. Adopting a five-year-old child during the short length of your marriage only made that worse. Now, it's time for you to move on, though you find it hard to do so.

    It isn't until you come across a city bustling with human and monster folk alike that things begin to change, the change leading you to meet new faces – both kind and unkind.

    It's then that you realize that – sometimes – what you really need is a moment of repose. You find yourself in the need to simmer down and for your mind to clear as a consequence.

    You're able to find that place the further you spend time in your new home. There, you form brand new relationships with monsters you never thought could exist – one of them in particular making you relive things you once thought were long lost.

    A save point – as you chose to call it – was something both him and you were in need of.

    Summary

    The year was 20XX. Monsters had been on the surface for a few years now and things were going smoothly. Mages, Monsters, and Humans lived in (mostly) harmony and life was peaceful...

    Well, for everyone but you that is. You were just a broke student trying to stay afloat, but you were sinking fast. Lucky for you, that's where magic comes in.

    The Arcana Core Tournament was just what you needed: An international contest of magic and prowess that only selected mages got to take part in for money, glory, and the secrets of the universe (probably).

    You certainly didn't expect to do well in it, nor did you expect to have a few adoring monster fans cheering from the sidelines. Magic celebrity life was not what you signed up for, but maybe making some friends would be nice.

    Summary

    Monsters living on the surface comes with a lot of changes to day to day life. For most, it brings a particular kind of chaos that uproots 'normal' a little bit more every day.

    In your case, it doesn't bother you much, or affect your day to day existence. They're just people, even if they look different from you.

    Life takes many odd twists and turns. That's just how it works. But if you’re honest, you never expected a stray dog to cause the biggest string of misfortunes and miracles in your life.

    At least, you're pretty sure...

    ... is the dog... playing matchmaker...?

    Summary

    You moved into a mansion. Very nice. However, what you didn't know is that your parents would FUCKING LEAVE. You were only a 12 year old! How would you survive? Well, you could, you were just being dramatic. One morning, you decide to make pancakes. When you discover you have no sugar, you venture to your neighbors house, to borrow some. Little did you know, for a cup of sugar, you'd make so many entertaining friends.

    And maybe an enemy.

    Summary

    There were flashes of memory from before. But when you wake up in a bed that isn’t your own, only to be greeted by a monster you’ve never met, you have no choice but to trust him. You feel as though he’s familiar in a way, that you’ve seen his face, or one like it... two, three times before? And there’s an itch in the back of your brain, like there’s something you left behind, someone even.

    This is the story of a human who came to be found by the Horrortale brothers, and nursed back to health after an “accident”. They can’t remember most of what happened before they were found in one of Papyrus’ many traps, and come to find solace in staying with the two skeleton monsters.

    This story takes place on the surface, in the normal timeline, but the skeletons have been brought together by means other than Sans’ machine.

    Summary

    A collection of stories depicting different points in different times and people's lives. Some of these stories are related. Some of them are not. It's up to you to figure it all out.
    Here's some clues:

    People are often stuck in situations that they don't want to be in. That's life, and it's best those people get over it. The sooner, the better.

    Some people think their situation is a lot worse than it is. They just can't seem to look at the other side and see the truth.

    Fear is something that can drive a person to the ends of the Earth. It can also awaken a courage belonging to the brave and the foolish.

    Some people think their lives are perfect. Until the moment they realize that it definitely isn't. Of those people, some will find the fix and others will not. Those who do not are likely to fall very far.

    Some say reality is what you make it. They don't often say reality is what makes you. A change in perspective can show a person just how naïve they really are, and that goes for both parties.

    (Basically a bunch of stories with my real life logic applied. Because I like things that make sense.)

    Summary

    One day, a strange phenomenon rips through the Ebott Valley Area a few years after the Surfacing. People vanished. Not just physically, but all evidence of their existence in people's memories and physical photos are torn away too. Like they never existed in the first place.
    Families are left without mothers, fathers, children at the table, and nobody stops to question what they don't remember.
    All that is left of the people that vanished are these cocoons that later hatching into small colourful creatures; somehow neither human nor monster. They can speak from the get-go and they have basic reasoning, but almost no knowledge of the world outside the care center they're placed in.

    And then there's one singing along to Bohemian Rhapsody.
