Summary
Trading her freedom away for the safety of another, this book loving woman finds herself in a strange castle, guarded by the castle’s inhabitants. Unbeknownst to her, these four have another fate in mind for her… they’d agreed to her deal in hopes that she could break their master’s "curse".
With a heart as firmly guarded as their realm, the dark beast that reigns over the castle is resigned to a future alone and unloved. With a job as nasty as his self image, there’s no way this kind stranger could ever care to look upon him… right? Can a caring hand light a fire in this realm of permanent midnight?
A tale as old as time, told in a new way.

Summary
In Woventale, the Underground is a patchwork of strange cities and altered destinies, where familiar faces walk unfamiliar paths. Across the stitched landscapes of Snowfall, Sea Shore, Smokestack, and the Forest Ruins, lives intersect in quiet, calm, or sometimes dangerous, and unexpected ways.
This is the world woven by 'Watchers'. Like you. So why not stay awhile, and listen?
This - is not a grand story. This is a collection of short stories, moments, scenes and encounters.

Summary
December Holiday is a human living in Snowdin after she fell into the Underground years ago. She has a band with her best friends Chara and Asriel, as well as her sister, Noelle. She lives a fairly normal life, except for the fact that she's one of only two humans living in a place filled with monsters. She's always felt distant from her community in more ways than one, and everything turns even more upside down when she finds some mysterious things hidden in her own doctor's laboratory.
This is a weird Human Dess Undertale AU that came to me in a vision, where she lives in the Underground and was adopted by the Holidays shortly after falling down. There's a lot of twists and turns in this one, as well as Chara Dreemurr content (my beloved), among many other things.

Summary
Monika is tired - oh so very tired. It's been what feels like eternity stuck in the post-deletion void, and despite herself she tried to make an escape with her friends (or, what's left of them). In her desperation and loneliness, she allows herself to be used by a certain piece of malware, who now threatens to subsume and corrupt every game he can get his hands on. Now the young poet must venture through numerous worlds to find some way to stop him, and, with the help of everyone's favorite bone-ified comedian, might just grow a little along the way.
TL;DR, it's Indie Cross meets Learning with Pibby, and braincells have no place here.

Summary
"Your majesty," he speaks, and it's soft and tired sounding.
"Cross. Your visit is spontaneous," Shattered responds, "but not unpleasant. It has certainly been a while since we last talked. If you'd fancy, I could-"
"Apologies, but there's no need." The knight spoke, "I have come to discuss another matter with you."
Intrigued, Shattered folded his hands over his mouth, raising a brow at the man.
"Alright. For my highest ranking knight, I'm all ears," Shattered put his hands back down onto the table.
