Summary
Ink is killed, one day, somewhere in the multiverse.
He returns a month later and life continues.
Two years later, Dream is mortally wounded in battle, leading to an imbalance between good and evil. Blue is in too deep, Nightmare is reaping the results of his actions, Error isn’t acting quite right. Morality stops being black and white as lines start to blur. A deeper force begins to seep into the constant battles, exposing the multiverse's rotting core and foreshadowing an era of darkness, the likes of which haven't been experienced since the X-event.
Ink was killed, once, planting the seeds of something greater than he could have ever imagined, and bringing him closer to the one person he never thought he'd truly understand.

Summary
"Resets", which you only actually learned about this morning, were a freaky time phenomenon which allowed something to travel to the past repeatedly. That "something" was a human, and that human wasn't actually human at all. That was what your journal explained to you.
(Or, Sans doesn't remember the resets, but he knows about them and he has to deal with it.)

Summary
Then they appeared. Three figures, emerging from the shadows, their forms dark and wraithlike in the dim blue glow.
At first, they seemed like nothing more than silhouettes. But as they stepped forward, more details emerged, each one more horrifying than the last. One of them - no, two of them - moved like animals, low to the ground, and one even crawling on all fours. Their bone-clad bodies shuddered, their movements unnatural, and Cross’ stomach turned. They were covered in a strange, greenish-black substance that glowed faintly, like algae festering on dead flesh. It clung to their forms in long tendrils, the sickly lichen-like growth looking as though it was the only thing keeping their decaying skin from falling off entirely.
After his disownment, Cross finds himself wandering the world alone, until a skirmish with some wolves leaves him falling for some creatures leaving in an abandoned city inside a Hollowed Mountain.
And they're just as loving as they are terrifying.

Summary

Summary
Frisk has faced danger and death many more times than any child should ever have to, but they aren't out of the woods yet. Being the first human in who-knows-how-long able to use magic has shoved them back in the spotlight. And just when their life was settling down into whatever counts as "normal" for the town of Ebott's Wake, where monsters sell ice cream and the gym teacher thinks anime is real.
It's nothing they haven't had to deal with before at this point, but that doesn't mean it's going to be easy, even with Papyrus taking over as Ambassador and the Finest scientific minds in the town working on a way to help Chara. After all, the first fallen human climbed Mt. Ebott for a reason, and it wasn't a very happy one.
And now, that reason knows about Chara too.Series

Summary
A field filled with dust and dried blood. A field where the last words and cries for help were drowned by the hits of sword blades.
The war between monsters and humans is underway. Started with fear and a feeling of insecurity, and it could end in any way. Both sides having only one goal: to save their home, from people they once called their friends.

Summary

Summary
Sans looked at the ceiling in pure boredom, unable to sleep as he listened the guards opening the gates of the inmates one by one. It didn't take long for him to hear a guard slamming his club against the bars of his cell.
He'd been told a doctor wanted to do check up on all the inmates, so he didn't really question it when he was forcibly pulled out of his cell so early.
Being pushed around wasn't fun, but at least it was exciting to meet new people that weren't convicts. They had a tendency to be assholes and not appreciate his humour anyway.
"Sans?"
He saw you, with half on your face covered by a mask as your eyes squinted in curiosity.
You were looking at him so intensively, it almost made him feel uncomfortable.
"Please, have a seat."

Summary
December 25, 2015
Mysterious black briars destroyed the whole of Ebott. Every inhabitant was lost except for a pair of brothers. Not long after, a tragedy claimed the younger one.
Since then, the sole survivor did everything he could to prevent the calamity from spreading further.
This story will use the following three premises:
- Soulless Post Pacifist
- Post Apocalypse
- Modern FantasyThis work is distinctly not the regular Dust Tale. It is an AU that strives to create a similar result using a path vastly different from the original. If you're looking for the true original, please go to their Tumblr blog at http://ask-dusttale.tumblr.com

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.
