    Summary

    Frisk's self-harm problem resurfaced after a big party she threw. She doesn't remember anything, but she
    has to find out what happened, and where the tool she used to self-harm is before anyone else will
    find it before her.

    Does it count as a relapse if she was drunk?

    Summary

    "The little girl just could not sleep because her thoughts were way too deep, her mind had gone out for a stroll and fallen down the rabbit hole."

    Frisk, a teenage girl of 16, wakes up after a fall and finds herself in a strange, magical kingdom of monsters.

    Only this underground world is not what it used to be.
    The king has turned insane and has been unseen for years. Meanwhile, it has turned cruel and oppressive as a group of violent and sadistic warriors known as The Royal Hunt work has taken control, working as judges, juries, and executioners, led by the mysterious self-proclaimed champion of the elusive King Asgore...

    Now, in this suffering kingdom, Frisk meets strange new souls and learns forgotten lore of a faded era, suffering through thick and thin and dying countless times to reach home, all while reality seems to sometimes break around her. Thankfully, she has one ally she believes she can fully trust.
    A helpful little flower called Flowey...

    WARNING: This is a dark and violent story featuring MATURE THEMES, GRAPHIC DESCRIPTIONS, SWEARING, AND GORE, so if you are too squeamish or simply don't like those sorts of things then I suggest you go back.

    ---
    A teenage human girl named Frisk falls into the underground after getting wasted after graduation, only to find a world of monsters all with her favorite thing: massive, throbbing, pent up cocks.

    Summary

    Undertale most likely took place over the course of a week, maybe a month if you really stretch it out. But what if, instead of weeks…

    …It took years? Frisk’s most important, integral, FORMATIVE years?

    But all those years have to lead somewhere, someplace, beyond the barrier. Reaching their breaking point with monsterkind, now 16 year old Frisk had to leave, and with their newfound 'freedom'…where do they go? Home?

    Where even is that?

    (Inspired by @Valdaessy 's own post-canon fic go read it its good!!)

    Summary

    Gaster’s life had been a simple one, built around a routine he found comfortable and familiar. Five days out of the week, he taught physics at the university where he worked, spending his lunch break with his two sons, both students at the same university. Each morning, he stopped by the coffee shop on campus for his morning coffee, spending a little more time there on weekends to work on his latest book. It wasn’t the most exciting routine, but he found it safe, familiar, it was his life.

    So when the university hires a new groundskeeper who basically wreck his safe routine…what’s he to make of him? It doesn't help that his appearance seems to have triggered a domino effect that just takes Gaster's life off the rails. This professor needs a nap damnit, he's too old for this.

    Summary

    Four years have passed since Frisk left The Underground without a king. Guilt plagues their soul for leaving their new friends in such a state, but fear keeps them from facing them. With each sunrise, Frisk's determination dwindles a little more... Hopefully, those close to them convince them to hold onto that faint courage before they give up on themselves.

    Summary

    Frisk... really didn't know why she thought the fall would kill her. She was literally made to be indestructible. Falling down some hole while thinking of dying wouldn't really change that.

    And now she's stuck in a random hole down Mount Ebbot.

    Great.

    Wait, except, it isn't just a random hole. It's a random hole which leads to a whole kingdom of monsters. (Only in species, not in the human definition of that. If she went by those standards she would be the monster here, not these painfully naive people.)

    Also, there's a talking voice in her head.

    And also, on top of her bullshit biology, she now has the power to bend time!

     

    Goddammit, why her???

     

    I have finally returned to the Undertale Fandom, and I present to you a complete rewrite of Determined to [SAVE]. Featuring actual worldbuilding, better writing, and an actual plot. Along with some actual defined power for Frisk other than "magic goes woosh".

    Summary

    A new life begins for you and your little sister, Neelam. That new neighbourhood is the chance you need to erase the past mistakes and those terrifying fifteen years you passed in a foster family.
    You are not the only one who’s running away from the past. Your neighbour, Sans, affected by a strange illness that’s causing him memory loss, is worrying you. At nightime, he’s wandering in the streets, lost, like he is chasing after old demons. His brother, Papyrus, can’t look after him for the moment. Since you are in desperate need of a job, he’s asking you to do that for him.
    You know it is not an easy job, but how complicated can that be when Sans is all but cooperative?

    Summary

    What if after a pacifist, the happy ending was only temporary? After all the effort Frisk made was just sending monsters to their own deaths. In between resets, somehow Frisk created an anomaly. A human on the surface falls underground when that would never normally happen.

    EDIT: Warning, this story has been reedited, if you are old, I recommend you to reread the story. If you are new, welcome and I hope you will enjoy the story.
