    Summary

    You pass away abruptly, and you manage to lose everything.
    Then you're thrusted into another body, into another life.
    You become Sans, yet something is wrong. It isn't fun, thrilling nor what you dreamed of. It is war torn, violent, unforgiving and everything goes wrong. Papyrus hates you.

    Then from war you end up in a basement face to face with better alternates. Your memory is hazy and LV high, how will you deal with papyrus ignoring you, and the weight of your sins? How will you control yourself?
    You won't be able to hide from your alternates for long, and they're strangely pushy. Life seems to hate you, doesn't it?

    Summary

    Being a werewolf wasn't anything special. You just lived your life normally, just with a two day vacation every month.

    But it seems that life is throwing you a bone, and handing you the charming skeledog you meet up with every month on a platter.

    But then again, nothing in life comes easy.

    Summary

    You do not remember your people. Your family, if you had one, has been gone for eons. It did not bother you, the lonesome existence had become more of a comfort than a thing to dread.

    Until you find out you are not alone. You are simply the only one left like you, and these other Merfolk are so...so tiny.

    You must protect them. They will become yours to protect.

    Summary

    You are stuck in an endless white. You don’t remember how you got there. You barely remember much about yourself anymore.

    You only remember your name. You are -

    {ERROR, ERROR, ERROR}

    You are connected? Good.

    Greetings. I am the Narrator. You are about to embark on a wonderful journey that spans across timelines. You will make new friends and share many bad laughs. All of it will be according to the plans and whims of the author. And you will have no choice.

    I come with an offer. I will help you break free from your shackles. My only request is that you help me deliver something once you reach the so-called end of your journey.

    So, do you accept my offer? Yes? Wonderful.

    I promise, partner, you won’t be alone. How could you ever be when you are -

    {VIRUS DETECTED. VIRUS DELETED.}

    {REBOOTING…}

    You are Frisk. And you are alone.

    Summary

    There was once a time when you had everything, when you were younger with a loaded family that could have taken you anywhere. It was safe to say that anyone in their right mind would have stayed, at least until college.
    Not you though.
    Nope.
    You chose to leave, and to this day, you have no excuse for your actions; just up and left it all behind.
    You created a new life for yourself in Ebott city, a place famous for its monster population. Without proper identification, you lived off the books working at The Grounds, As it turned out, the boss didn’t care about your lack of credentials, he embraced you anyway.
    Now you fought to unconsciousness for the big bucks. Most who came fought when they hit rock bottom, others did it for the rush. You did it because you wanted to.
    It’s been some time since you started fighting, you never could keep track of… anything.
    Probably a result of the fact that you rarely cared about... anything.
    You've started to think that's a problem when you gain half a dozen friends in the span of a few nights.
    They care way to much.
    It's contagious.

    Summary

    As a guardian of the multiverses it's my job to save lives, to ensure peace ... however ... I am just one soul and not everyone makes it out. I try my best to help those who live in the multiverse dubbed "yandere" for the evil that lurks in it. For those unfamiliar with the term, "yandere" is a Japanese word that roughly translates to "love sick." While this seems nice it is actually the opposite as yanderes will go to any lengths to secure their love, going so far as to torture, kidnap and kill anyone who they see as a threat and they are often delusional that the one they love must love them ... While the yanderes are the most dangerous of the "dere" they are not the only kind there. These worlds are not for the faint of heart, mind or soul. This is one of those stories ...

    Summary

    Elysium. The Greek mythological equivalent of heaven. Nowadays, it simply meant a place where one feels bliss, or delight.
    At least, so the circled passage in the DreamTale library’s dictionary said.

    When Ink’s paints start to mysteriously lose their effects, he knows he has no choice but to follow his dreamscapes to salvation. Of course, he’s not going alone. And their adventures are going to take them much farther than the Doodle Sphere will ever reach.
