    Summary

    After getting to the surface after so many years of isolation, one would think that positivity would come easily. It's what Sans thought too; hell, even believed. However, happiness never seems to be a typical emotion for the poor guy. After Sans finds a mysterious photograph that he doesn't quite understand, he begins to dwell on things he can't remember but can't exactly seem to forget either. Will his ominous past finally consume him, or will he be able to free himself from the underground's suffocating hold... especially after so many years of being left in the dark?

    Perhaps all one needs to escape the shadows is for someone to light the way.

    Summary

    Kris and Susie have been going back to the Darkner World for at least a month now.

    Then Asriel comes back from college.

    Now the Spade King escaped prison, and sometimes Kris could've sworn they've seen the trees turn into a familiar red and purple from time to time.

    Now they've got to talk to some others to figure out what's going on; a particular skeleton that seems way too familiar, a little chaotic gremlin with a broken stuff toy for a friend, and a few others that seem too odd to be seen with color.

    Summary

    Counting up. Fifty. One hundred. Two hundred. How high can you go?

    Frisk has been running around the Underground for the past three days; he's been able to condense several years into them thanks to his inexplicable control over time. At first, it was an exercise in patience, a check to see what works and what doesn't on his mission to get back home. But something always seemed wrong. Trapped in the void at the edge of the Barrier with nothing but his phone, he would reset. And reset. And reset. Until finally he got it right.

    But by that point, the iron will to save everyone in the Underground was too strong to ignore. Do you know that feeling? Maybe you've felt it before?

    So he went back. And he went back again and again and again. There's got to be a way to save the one who matters. It'll take some time and some help, but there's got to be a way.

    Summary

    You went to the bookstore one day to buy some manga.

    You got a whole lot more than you bargained for.

    You end up somehow saving the Royal Scientist's life, and her fiancée can't thank you enough for it.

    So that's how you find yourself surrounded by people who love you for who you are and don't want you to change.

    But what's up with these strange dreams you're having? And, why does a certain punny skeleton get so spooked at the number 17? And...who is that tall skeleton with cracks in his face that you keep seeing in your dreams? Did the ambassador of monsters just join your swim team? Can this summary get more cliché?

    Summary

    How, then, does one define a ‘soul’? Is it developed over one’s lifetime or the moment they are born? Are some naturally evil, rotten from their very core, or is such a thing learned? Does it have something to do with genetics? A difference between blood and magic?

    How do people grasp the idea of what makes them themselves when such an idea is easily discarded?

    OR -- the AU in which a monster absorbs a human soul and the consequences that come from messing with the continuity of the multiverse.

    (ANOMALYTALE is a mix of previous ideas/AU's ive messed around with over the years, including my old & abandoned au, devastationtale. some chapters may be unsuited for certain people, so please make sure to read tags/warnings before you read! hope you enjoy!)
