    Summary

    After thousands of unrelenting resets, Frisk has finally acheived it- the truly perfect ending. Asriel was saved, Chara was here and she even brought back the long lost W.D Gaster back from the void! With the help of everyone, they even got Goatdad and Goatmom to be together again! And to spruce things up, they all live in one big house together. Everything felt like it was to good to be true, just perfect. Everyone should be happy, right?

    Sans's night terrors has gotten worse over the past few months. The comedic skeleton avoided all of them to settle it by himself but his dear family was sickly worried.

    And so a memory machine was built, though Frisk had a baaad feeling about the turns of event.

    Summary

    All he'd expected was a short trip to the park. Nothing more, nothing less.

    Obviously, as all things are, it didn't end up that way.

    Now here he is, at the hospital, with Tori's kid and he has no idea how the heck he's supposed to explain this to her.

    And that's not even mentioning you.

    Of course, out of all days, it just has to be today at the exact same hospital that he meets his soulmate.

    Summary

    Elena's vivid dreams started after finding that old leather-bound book with the strange emblem in the library basement. Dreams about a race of strange yet kind sentient creatures trapped under a mountain. The book had sparked and impressed upon her childish imagination so much that it was all she could think about. She was increasingly finding herself daydreaming about the "fictional chronicles" in that book to the point it was seriously affecting her current work project. Yet as much as she tried to focus on her work, she couldn't stop remembering every word and illustration that had planted itself in her memory.

    This was a problem. A very BIG problem. Her daydreaming is what made her oblivious to the car that ended up ramming into her and placing her in a coma.

    Somehow, instead of experiencing complete darkness, she somehow found herself in her vivid dreams.

    "There is no way this is real. I'm dreaming... I'm having a really vivid lucid dream...RIGHT?!"

    Summary

    It's been over 50 years since the start of the turf war. Ever since the monsters and humans attempted to co-exist with each other all of those years ago, fierce and intense conflicts started to rise between the two races. Even after all this time, the war still continues to rage on.

    The notorious "Skelebrothers", Papyrus and Sans have risen to prominence during this period of time, and are now two of the most feared--and hated--pair of monsters to ever walk the monster cities' cold, unforgiving grounds.

    The story that you are about to read revolves around the eldest Skelebrother, Sans the Skeleton, as he uncovers the untold, dark secrets of his past, the reasons as to why neither brother is able to remember where they come from nor why this intense war broke out in the first place, and the discovery of a deep, twisted romance brewing between the two skeletons.

    Welcome to the cruel world of "Blood n' Bones."
