    Summary

    Asra was raised by monster hunters. They had their origins in the war that time forgot, when the human-aligned mages locked away the monsters underground...or at least the ones they were able to catch in time. Those who remained went on to earn a place in various local legends, scattering all over the world for their own safety, and largely fading to the realm of myth. This earned her family none too good a reputation in historical circles, as they continued to insist on their version of events.

    When her mother sent her to investigate the Mt. Ebott disappearances, she wasn't expecting to learn that the old stories that ruined her life growing up were true. Now she had a choice to make....

    Summary

    It's been a few years since Monsters and Humans have made first contact. While there is peace there's still plenty of tension. A mini summer vacation to a small town should be good, till the Alien Invaders show up.

    Summary

    Sans/Reader fluff and angst! And angsty fluff! And romantic fluff!
    Every chapter is its own story!
    Prepare or tears and happiness and other stuff!
    You can read this apart from the first work in this series, but I carry a lot of stuff over from that one, so I'd read it first to make sense of some of this stuff. I really only started a new work because I was worried the other one was getting too long.
    Thank you to everyone who supported me and left kudos on my last work! These are basically 1/4 canon compliant, because most of it is me talking about ships and stuff.
    Anyhoo, you just got back from Colorado, and immediately things start getting weird. How will you and Sans handle it?

    Summary

    * I thought I had warned you about that guy. “Don’t let him find out ANYTHING about you”, sounds familiar? … Oh, but that’s right! I forgot you NEVER listen. To you it was all just a game after all, wasn’t it?
    * Hee hee hee. Let me give you a little tip then: the Game is a Lie.


    * Echo Flowers repeat what they hear, babbling back and forth to each other until their words become meaningless noise.
    * What used to be the “truth”… soon becomes too distorted to appeal to anything you thought you knew.
    * Never trust a flower. That’s one of the constants of this world.


    After trying everything he could to stop time loops from ruining his life and universe, Sans has finally figured out the truth. As a last resort, he finds out that he has no more choice… but to ask for help.
    May 1st, 2016. Undertale has existed for half a year, and its fandom is raging at its full potential. But then, a Player disappears.

    Summary

    After reliving the same traumatic events over and over again, Frisk can see that Sans doesn't have much left to give. With each reset that steals away their happy ending, Chara is getting a little closer to breaking the monster completely.

    Sans is hanging on by a thread, and Frisk knows eventually that thread will snap.

    Filled with desperation and determination, Frisk does the only thing she can. She calls for help.

    The mages, her Den, that answer the call may just be enough to save the underground. They may just be enough to save Sans from what he has endured for so long and remind him that someone out there cares a whole lot about him.

    Summary

    Ages ago, before Chara, there was Frisk. But Frisk didn't come alone.

    Now, the barrier is broken, and Chara is acting strange. Curious and wary, Papyrus follows the teen into Hotland and discovers a secret Gaster had taken with him to the Void.

    With the Barrier broken and Mages showing up on the mountain, none of the Monsters know what to expect from humanity anymore. And humanity definitely had no plans for the Monsters.

    Summary

    Moving from a backwater town to a city bustling with human and monsterfolk alike, some things begin to change both for the better and the worse. What was left behind comes back to bite at you in the most unexpected times, current progress being put in danger as a result. It's hard to move on, though it's equally difficult trying to stay loyal to what you believe is right.

    With an adoptive seven-year-old son and the remnants of a recent divorce in your hands, your goal is to move on and adjust to life with monsters, these becoming an important part of your life -- one of them in particular reigniting the spark you thought gone with your ex spouse.

    Summary

    His skull shines from the sun as he looks through the glass at you, his face wearing a bright but also lazy smile. He gives a small wave, which you returned politely before settling back into the pile of pillows.

    He seems to take the hint and turns around, engaging in conversation with the rabbit monster. While his back is turned you take a closer look at him.

    He wears a blue jacket with a grey hoodie, black shorts that have a white stripe down the sides and pink bunny slippers. His stance screams lazy and uncaring of the world around him. Cool.

    You haven't even said a word to him, but you already hope he sticks around.
