    Summary

    Derringer is the queen's Enforcer, but not by choice; the Underground is underneath a tyrant's thumb and no one seems to be able to defy her except him... and even then it has led to his personal suffering as he tries his best to stay between the tyrant and the innocent monsters she wants to dust for her own amusement or stupid whims. He knows that he cannot keep up this forever and his brother, second to Captain Alphys of the Royal Guard, could be left on his own if ever the tyrant had reason to dust him. One day, while on his way back from the usual day in court, he comes upon a strange monster in need of help ...

    Summary

    Why is it so cold when you're in the sun? Why does food not satisfy? What douses your good days in spirals of thoughts that you don't control? Why do you feel so hopeless when you're doing fine?
    The answer may surprise you.

    Soulmates? On my PC? It's more likely than you think!
    In all honesty, I haven't the foggiest on what I'm doing, but I hope it's good.

    Summary

    Two years after the events of the neutral pacifist ending and a new human has come to the Underground.

    But, you are neither a child, nor are you innocent by any stretch of the imagination.

    Who are you? If you're so nice why do you have such an ungodly LV? And what's Frisk going to do?

     

    Edit: Updates will most likely be delayed due to computer destroying the other chapters I had written ahead. Got a lot of catching up to do.

    Summary

    Undertale is a popular video game, but it knows when it's being played. Five of its characters can remember the way the world used to be, even after the game itself resets, but until now they have been unable to affect the outcome for the better. As such, this game has never once gotten its happy ending and, as such, is adapting. Two wrongs make only a greater wrong, after all.

    This is No Mercy Route Number Ninety, and five alone will have to change the course of the game, before the game changes them.

    Summary

    Based off the Amazing World of Gumball episode, ‘The Night’, follow your favourite Undertale characters as, after a long day, they climb into their beds, fluff up their pillows, lay down their heads, and drift off to a magical place.

    The land of dreams: a place not bound by rules or limitations. A world where anything can happen, and where anything is possible. Where the greatest joy and deepest fears can be found. Where fortunes are lost and found every night.

    Where will the dreams of such weird, magical creatures take us? What wondrous, mysterious things will we see?

    The answer lies inside, dear reader.
