    Summary

    Little problems plague the world of Underfell, even above-ground. It seems like, just as the monsters have made it into the light, issues long buried are slowly being unearthed as well. Issues of lost friends, resentful little children, demons, and unstable dummied-out space. It's a shame; Frisk was just getting used to being out of danger again.

    And as the world of Undertale has already learned, Underfell's issues are infectious. Can the two worlds help each other, or will they only compound each other's problems?

    A continuation of "The Many Worlds Theory Sucks" and sequel to "This Game is Too Hard".

    Summary

    Papyrus gets shunted across universes and ends up in a place that is nothing like the Snowdin he calls home. There's no warm welcome to receive him; only the all encompassing feeling of danger that seeps into his bones. Though, maybe calling them his bones would be a bit of a stretch considering he's no longer in his own body. Instead, he has a scar over his eye, pointed claws and teeth as sharp as knives. He's desperate to get back home but, between searching for a way back and keeping up appearances with a sad little skeleton that looks an awful lot like his brother, everything is kind of a mess.

    He can't stay here though. There's just no way.

    So he'll simply have to try harder.

    Summary

    Marrying at twenty and divorcing at twenty-two doesn't exactly leave the best image of you. Adopting a seven-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

    Frisk has faced danger and death many more times than any child should ever have to, but they aren't out of the woods yet. Being the first human in who-knows-how-long able to use magic has shoved them back in the spotlight. And just when their life was settling down into whatever counts as "normal" for the town of Ebott's Wake, where monsters sell ice cream and the gym teacher thinks anime is real.
    It's nothing they haven't had to deal with before at this point, but that doesn't mean it's going to be easy, even with Papyrus taking over as Ambassador and the Finest scientific minds in the town working on a way to help Chara. After all, the first fallen human climbed Mt. Ebott for a reason, and it wasn't a very happy one.
    And now, that reason knows about Chara too.

    Summary

    Try as I might, I couldn't find many fanfics about the 6 human souls from Undertale! So I decided to give it a try!

    Follow the journey of each as they go through the Underground.

    I promise there will be a happy ending.

    I can't, however, promise I'll get to that ending this year, considering my upload schedule.

    It worked.

    He could travel to other universes now, find one where Monsters had broken the barrier, free his people, show his sons the stars.

    Well, if he didn't get sidetracked by the angry copy of himself and the two damaged boys watching him with broken eyes.

    Summary

    Five months since monsters have returned to the surface world having broken all bonds, the world is changing... in some parts.

    You`re still a bored, tired student, and you`re sick of all the expectations following you around like a creep. You`ve studied way too much, you`ve studied out your entire youth. Now, in a foreign country attending to a foreign university, you decide this is the perfect moment to get away from your hell of a life for a moment.

    You take a break and a semester off, overjoyed at the thought of being able to chill all day with your sweetie of a roommate.

    Little did you know, your roommate was a scientist. An experimenter, at that. And now he`s done something he has to undo. But in the meantime, he has got to take care of whatever he has done.

    So he invites in a horde of skeletons inside...
    And apparently, they`ve got NO chill.

    But heck, who doesn`t love some turns in a boring, bonely life?

    Summary

    “Despite everything,” Sans said, “I still love him.”

    ***

    What would it take to be forgiven for everything you've done?

    Would pacifism and kindness extend that far to love such a disgusting being like yourself?

    After everything, all the change, the conflict, the chaos, and mending the world you broke,

    Would they still love you?

    ...

    Did they even remember anything?

    Summary

    Dr. Wingdin Gaster kept his experiment, 6 (Sans), hidden from the outside world. An unexpected visit from the king forces his secret into the open. Not knowing anything other than the lab for the entirety of his existence, 6 must reconcile the world he's known with the world he's been hidden from. This is a story about good intentions, bad mistakes, and the fine line between being a monster and being human.

    Warning: Because this fic seeks to tie up some loose ends of the UT backstory, spoilers abound. Don't read if you haven't finished playing the game through to your heart's content.

    Summary

    War, as Death's herald, is a strange and wondrous thing. In its own unique deleterious way it is both judge and jury, passing sentences unto all regardless of creed or privilege. Like a disease for which there is no cure, it spreads unchecked and spares none terror, grief, and despair without equal.

    Might it be possible for this, a catalyst of destruction, to unify? To deepen bonds?

    Herein lies twin tales of kinship among four distinct souls, forged by trials and tribulations of mortal coil.
