Summary
Or: The one where an adult Frisk wakes up after their funeral, back at the beginning of everything. Of course, they know how to navigate all their adventures underground, but... Does anyone want to tell them what kind of sin they committed? After waking up each time, in different timelines, some of which they even know they generated, and others that they themselves didn't commit? Yeah, this isn't going to happen (it happens anyway).

What's even the point?
They tried everything.
It's hopeless.
They should just give up.
*But it refused.

Summary
Papyrus knew something was wrong with his brother—people didn't drop their HP Cap for good reasons, after all. But last he'd checked it was much higher than ONE. With terror in his marrow and his brother staying stubbornly silent about whatever was going on, Papyrus decided it was time to call in the cavalry, because he would be damned if he stood back and watched his brother Fall Down and Dust without doing anything.
OR
Papyrus realizes that being on the Surface hasn't helped his brother's crippling depression, because his HP is still 1. So he decides to bring the others in on his brother's stats to try to help.

Summary
"Amaranthine: Immortal; Undying; Unfading."
2 Years.
2 Years since they fell into the ruins.
2 Years since they had freed all monster kind and managed to have brought back Asriel and Chara.
And 2 Years since the beginning of a new era.
Frisk and Kris, the siblings that were adopted by the Dreemurr family, have started a new life in Hometown, Humans and Monsters finally at peace. It was great. In general really. However, Asriel and Chara had gone off to college, and Kinnsley, the duo's sister, was being homeschooled as per her request. The Dreemurr siblings wouldn't exactly call their life bleak, but it was like any other normal school.
Jared and Jenna Tumbles, a pair of twins that have recently moved into Hometown next to Frisk's and Kris's house, have met the siblings before when their parents had met up in a playground. Now, they got along just fine!
Until Jared and Kris might be wondering if they're falling for the other.
With school life, the upcoming festival, and the realization that they'll have to tackle their trauma soon, the kids make some unlikely friends along the way-both lightner and darkner.

This is not a tale of slaughter for the so-called "greater good".
This is a tale of one who has grown tired of such slaughter, bringing justice to so-called mistakes of the multiverse. A tale of a faceless killer... of "Dusttale's Endbringer".

Summary
The arrival of monsters from Mt. Ebott threw society into disarray. Not only was a previously unknown species discovered, but the shattering of the barrier released centuries of magic back into the world. As society struggles to move forward from their bad history with monsters, MOPA, “The Monster Obligated Placement Act” was formed. As such, all mages must provide housing for a minimum of one year for a MOPA designated monster family.
Having jumped through enough hurdles to kill a horse, you are finally forced to house a family of your own.
Between eight skeletons of varying color schemes, your reluctant past, forgotten dreams, and a desire to make up for your sins, you are forced to use your wits in a world breaking at the seams.

Summary
She’d stared at the yellow petals in her palm. Buttercups. Harmless-looking. Beautiful. Poisonous. She chewed slowly. Her hands didn’t tremble. Her heart pounded. Asriel had begged her not to. She’d smiled through the pain. “I’m not afraid,” she had told him. But she was. She was terrified. Still, she whispered: “Somebody had to do it.”

Summary
After years of lock down under Mont Ebott, the Monsters thought that Frisk's fall would finally put an end to their miserable life. Because they was pacifist, everyone thought freedom closer than ever. But Asgore's murder deadly hit every last piece of their hopes and dreams.
The events are getting out of control. Undyne and Toriel engaged a no-mercy fight to get the throne, each one with extreme opposite ideas. If the old queen wish for peace to come back, Undyne, traumatised by her mentor's death, only wants a war that would sign the end of humanity.
Far away from all these politics, Sans is waiting. He knows that Frisk never would have kill Asgore on purpose and that they are far from the horrible monster described by Undyne in her destructive propaganda. For the first time in a while, he's still holding on the promise the kid made : coming back to break the Barrier. That dangerous way of thinking might cost him everything he ever had down here.
But the day the CORE stopped working, all of them will have to make dangerous choices despite friendships and betrayals. Down here, it's walk or die.

Summary
Over the past few months Frisk has become more withdrawn, spending less time with their friends and family and more locked away in their room.
Feeling as though she failed her child, Toriel wishes for an explanation, so that she might understand her child's pain. Fortunately for her, that explanation arrives just in time.
"Oh yeah," thought Chara, bitterly, "because nothing is better for a child's mental health than having everyone witness their trauma in HD."
