Fallen

The multiverse of Undertale is vast, and it's virtually impossible to document all the AU's.
Which is probably why no one knows who this mysterious girl, Alyssa, is.
A story involving Classic!Sans, Fell!Sans, Ink!Sans, Error!Sans, Blueberry!Sans, and a whole lot of shipping, the cast of Undertale and its AU's come together in this tale of searching for where you belong in a place you know you're not meant to be.
I do not own Undertale, Underfell, Ink, Error, Underswap, or any of the other AU's and characters. The only character I own is Alyssa.
There will be an author's note at the end of every chapter. All art is mine unless otherwise stated.
