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
It isn't fair. It isn't fair that Papyrus has so much HP, and Sans has so little.
If only Papyrus could give his brother some of his own strength; his own health! He had plenty to spare! If only he could give Sans just a bit of it!
Or... perhaps more than a bit.

Summary
“Sans!” Papyrus’ voice broke Sans from his thoughts and he turned around to see Papyrus holding a tiny fluffy animal on his lap which they’d learned was a “kitten.”
Papyrus’s eyelights were heart-shaped and glowing and a wide smile stretched across his skull.
“Sans! It is adorable! This little creature immediately approached me and started rubbing its face against my rib cage. All while making the most peculiar rumbling sound. It likes me! I think it wants to come home with us!”

Summary
“As always, humans first.”
The crowd was silent, clearly unenthusiastic. You tried not to think about your odds — it never did you any good. What was six slips of paper as opposed to hundreds?
With a shaky breath, you quelled the hammering in your chest. It will be okay. You do this every year, right? Every year, you come to the square, watch two members of your community be sentenced to certain death, then go home and silently contemplate the conditions of your world. That’s how it went every year, and you were certain that is how it would go this year.
So when the cold metallic voice announced your name over the loudspeaker, you could feel your heart stop.
Ice shot down your veins and a ringing filled your ear. You thought you could hear your mother scream, but she sounded so far away, you could barely register it. Was it really… it was you?
Another announcement of your name, followed by a sing-song, “come up here, darling!” confirmed yes, you. You were the human tribute of District 12 in the seventy-fourth annual Games.

Summary
It's easy to think about those who are important, how they would interact with eachother and in new situations...
But what about those outside of that box? Who are more free to move, do, and be as they please? What about relationships unmentioned, unwritten, unexplored just because they simply are not important to who perceives it all?Perhaps what can be said, be seen, be experienced...Are still not that important. Not real. Just things that seem like fantasy.
But still...New things can be considered, if you simply take a look from a new angle.A collection of disconnected writings from the perspective of a mere background character, Doggo.

Summary
A fanfiction set after the Pacifist route. The characters you love are here : growing, evolving, finding their place on the surface. But with change comes the unexpected. And nothing will unfold quite the way you imagine.
New faces will appear too, including a young human woman who gradually becomes part of the group, discovering them, and herself, through fresh eyes.
This is an immersive story. Unpredictable. Sometimes funny, sometimes emotional, sometimes unsettling. Chapters will shift in tone and length, often illustrated, and with interactive moments where YOU get to decide what happens next. Just like in the game, you’ll have power. Or at least the illusion of it.
Forget what you know. Forget what you’ve read. Set your expectations aside and take the plunge.

Summary
If you were to be asked whether or not you liked your simple, isolated, peaceful life, you would say yes, you did. If you were to be asked whether you would ever like to leave your home and travel the greater world, you would say you weren't sure. If you were to be asked if you would like to stay in your home for the foreseeable future, however, you would say yes, you did.
Unfortunately, the infamous captain Sans Font wasn't going to give you a choice in the matter.
