Go To

What is sanity to the mad? What is madness to the sane?

A child on the run, mired in what they believe to be the True World, falls through the barrier and into the land of Monsters. They are found by the prince Asriel Dreemurr, taken into his family, and given kindness and warmth they thought was long left forgotten.

But their arrival has other consequences. As impossible as their arrival seemed, it is only the beginning, for more humans are already on their way.


And this child, who has finally found a family and a place worth protecting, will stop at nothing to keep the humans away.

On the Edge of a Knife is an Undertale fanfiction by Evaunito 2 Mark 1, hosted on Archive Of Our Own here.

On the Edge of a Knife contains examples of:

  • Eye Scream: By the end of Wander's first fight with Sara, she's stabbed out both eyes. Only one recovers prior to Chara reforming from Wander's body after they attempt to kill Sara/Assassin a second time.
  • I'm a Humanitarian: During a display of The Chosen to Wander and Sara, The Yellow Chosen casually eats a food offering given to them by a shaking child, and then just as casually bites their head off completely seconds later.
  • Oblivious to Love: Wander and Asriel to each other for quite a few chapters, though Asgore, Toriel, Gerson and even Undyne can see their affections for each other plain as day. It isn't until about halfway through the fic that they admit their love for each other.


How well does it match the trope?
