Civil War looms over the Underground.

Note: This is NOT a story. This is an archive containing information about my AU, Desert Sanctuary. I might write a proper story in the future, but for now, this is where you can read about the narrative, the characters and how this massive change affects Frisk's journey.
Fanart and other fan works based on Desert Sanctuary are welcome and encouraged

Summary
A sweet little series set in a world where monsters had been captured from the beginning instead of shoved underground.
Eventually, as the years and generations pass, both humans and monsters slowly forget the monsters were ever free.
We follow the story of an aging little zoo hoping to expand and take in a few monster pups. And the stories of several monsters who find themselves being transferred to the place.

Summary
The background stories for the Bitty Murder Time Trio from my story "Sir These are Bitties".
Think of the Murder Time Trio as Bitties, with their stories altered to fit that theme. Pet abandonment, fighting rings, etc. For example, a main core theme in most fanfiction/fanworks have Dust kill/tragically lose his brother. The main focus of Horror is famine.
That is why I will have their background stories in this collection and not directly in the main story of "Sir These are Bitties", the main story is a lot more light hearted. But I think the backstories are important, it shows why the Bitties are so loyal to Nightmare, plus it's interesting to explore.
Added relationships tag of Sans/Sans, in the main background storylines, it starts as a crush. The main Sans/Sans relationships are in the main sections of the "Sir These are Bitties" and the rest of the story collection.

Summary
Another Genocide
Sans had not known why the Human continues to do this. He doesn't think he wants to know. After seeing from their expression that he had dunked them multiple times, he truly started to feel disturbed as they relentlessly continued again and again to get him to the halfway point where he would offer mercy through death.They had accepted.
They were dead once more after professing their love.
He rested against the pillar, steadying his body against it as he slept. And when he awoke, he was far gone from the Underground he had learned to accept as somewhere he was going to be stuck in
"this... this can't be good, right?"
You're right funny bone man. You're right.
TL;DR: Sans is taken to Re: Zero alongside Subaru Natsuki. Chaos ensues with the funny bone man there to haunt them all.

Summary
Imagine if the person who fell to the UNDERGROUND wasn't Frisk? What if it were someone completely different, someone in control of not only their choices, but their powers as well? Meet Grace, a young adult who just happened to be walking through the woods the same day Frisk decided to fall. Grace managed to SAVE Frisk from their usual fate, but only in exchange for hers; Grace falls down into the UNDERGROUND. As she makes friends and walks through the UNDERGROUND, read to see how a different character might have made her decisions on the same path an innocent child took - and how she might ruin it.

Summary
Frisk was the light of your and your grandmas life. You always spent time with them with any free time you had, and if you didn’t have any you would make some. Then suddenly while stuck at work you got a call about Frisk’s disappearance from your grandma.The police force had no leads whatsoever, leaving you with guilt, what ifs, and sleepless nights.
Two months later you had arrived to your house to frisk wrapping around your body, crying. You were as well. But you guys weren’t alone in the room. Monsters were within your house, they were actually pretty nice. Talking goats, a charming short skeleton with an enthusiastic tall skeleton brother, a strong, loud, and happy fish lady, and a shy nerdy lizard scientist.
They spoke of magic. A whole kingdom underground, beneath your feet. And how Frisk came to save them all.
If you ever told your past self you would be falling in love with a skeleton, she would’ve laugh in your face.

Summary
DreamTale collapsed centuries ago, one of three entities for the fundamental building blocks of the multiverse, gone and rotten.
But what of the pressed leaves and blossoms, kept as a desperate attempt to hold onto what once was?
What of the AUs collapsing in on themselves seemingly at random, with little to no trace on why or how.
What of the small monster running around Nightmares dungeon, not quite a Sans, and yet so strikingly similar to one?

Summary
- THUMP THUMP -
There it was, the unmistakable sound of Kris’s SOUL trying over their movements, their actions, their emotions…
‘No… not now please’ Kris thought to themselves, begging the SOUL to not make them stay, to make them suffer here alone in this empty room.
- THUMP THUMP, THUMP THUMP -
The SOUL beat in their chest louder, the rhythm picking up like a cars engine trying to start.
Sweat began to trickle down Kris’s forehead as they fought off the sensation of numbing that came on when the SOUL would take over. The cloud of fog within their brain that washed over them when they couldn’t do anything.

Summary
One moment, you’re living a dull life, following the same routine day after day. The next, you wake up trapped in a cold, unfamiliar place, surrounded by bars and creatures that aren’t human. Your purpose here? Maid. At least, that’s what they say. But there’s more to this dark, twisted world than simple tasks. The figures watching you from the shadows have their own plans, and you're nothing more than a pawn in their game.
is this good enough or what? JUST READ IT ALREADY!
