Summary
Once upon a time many centuries ago, the world was ruled by two species: Humans and Monsters. Both of these creatures thrived together using their special talents to help one another. That was until the humans declared war on the monsters out of the blue. This led to the monsters to be banished beneath a mountain.
But rest well when I say the humans suffered their karma. Without monsters they soon lost their magic, along with their way of life. They developed their own powers called quirks, with this power came the raise of heroes and villains. Quirks were quick to spread until only 20% lacked them.
It wasn’t long before magic and monsters were reduced to legend. This led many to climb the mountain to see if the legends were true, only to never return. This was because of the heartbroken monster king who put a bounty on every human who fell.
When the last human fell, the monsters were ecstatic. Finally they’ll be free to wander the surface and feel the sun and the rain again! But unbeknownst to them, they have become even more trapped than they had before. With each reset the monsters were forced to live the same day over and over without anyone knowing ... .Well, almost everyone.

Summary
Spanning over ten years, this huge fic will be split into ten parts for each year.
This fic is Alphynecentric, with Alphys at the helm. This is a fic that came outta nowhere (as they all do) and hasn't quit since I started. I have no idea where this will go. All I know is that it is very emotional, romantic, and rather silly.
Just enjoy. This may be my last fic for this fandom.

Summary
The Multiverse was frozen.
Deep, black ink dripped from the code of AUs.
Nothing new was being created, and nothing could be destroyed. Everything felt definitively fuzzier at the edges as the balance of energies refused to tip for anything...The entirety of the Multiverse was decaying, slowly but surely, and it was all because a certain Creator has gone missing...

Summary
The Barrier is down, monsters are walking the streets, and reality just got a lot stranger.
Rhea is human, unprepared, and stuck in a house full of wildly different, unpredictable skeletons. Some are warm, some dangerous, all impossible to ignore. Pulled through by a mysterious machine, she’s trapped under their watchful eyes while the multiverse starts leaking into her life.
Rhea navigates the household of chaotic, flirtatious, and often deadly skeletons, while trying to come to terms with her new fantastical, but very real reality.
Darkly funny, magically strange, and dangerously charming. An urban fantasy reverse-harem story about survival, trust, and learning to live among the bones. -

Summary
Noriko works for the Ebott police department in the newly established special bitty unit, her first assignment to go undercover to get into the bitty fighting rings now that the government has given the small monsters all the same rights as their full sized counterparts. What she didn't expect was for her first assignment to have a hiccup in the form of finding something unexpected in an ally on her way to make contact with her in into the rings.
Life in the rings was hell, being sold off to be a breeder was probably even worse. Though dusting in some filthy ally by the jaws of a mangy mutt was not the way he expected his great escape from hell to end.

Summary
“Thanks, Paps.” Sans replied, taking the blanket and dropping it over the sleeping human. Proceeding to give the child an affectionate pat on the head. The sight made Papyrus think of when he and Sans were younger.
Seeing his brother in such a state filled Papyrus with his own feeling of euphoria. After all his brother has done for him, even including all the times he has annoyed him with the puns, Papyrus felt that Sans deserved his own bit of happiness. His own chance to have the life he wants.
Or essentially five times of others witnessing Sans acting as a Father towards Frisk, the one time he admitted it.
