    Summary

    The barrier is finally broken, and at last all of monsterkind are free to walk on the surface.
    Again.
    Sans the Skeleton is skeptical. Why bother getting excited for something that's just going to reset? This is not the first time the barrier is broken, and probably not the last. He feels the need to take a break for everyone else's enthusiasm and wanders to the ruins where he encounters a ghost of his past. The result of that meeting is something he has been hiding for a long time and that he's determined to keep hidden.

    Summary

    Some say the prophesy calls for the war to end in a pool of blood and a blanket of dust. Some say it foretells the fall of the Fell King and a new era of peace…

    Red hasn't cared about the stupid prophesy in years. He has more important things to deal with. Slim won't tell him the truth about what happened all those years ago. Razz is struggling to hold himself, and the kingdom, together. And now Red has to smuggle the enemy into the castle, protecting and hiding him until he can finish healing.

    To make matters worse, the enemy has the biggest blue eyes, and the widest smile, and-‘Shut up, Edge! Get out of my head!’

    Summary

    Flowey has finally attained the godlike status he deserves, and with his newfound powers, he can show everyone the true meaning of this world. But, just suppose, how lonely it would be to be the last being in the world? Even evil loves company.

     

    Deltarune got me back into the mood for Undertale! If you've read my previous fic "All There in the Name", you know what kind of shit I'm about. This fic is actually a sequel to that one, so go back and read it or some elements of this story may not make sense! Also, make sure to read the warnings and tags, which will be updated as future chapters come out.

    Summary

    So, since I suggested it and people agreed: Here are the descriptions of several AUs that just aren't fleshed out enough to be a full-fledged AU or that I'm just too tired to write it as a full story.

    Though one day I might, I don't know?

    But if you think you can do something with these AUs, please contact me so I can see how it goes and you are more than free to use them.
