Summary
It has been five years since monsterkind left Mount Ebott with the help of Frisk. Now a teenager, that’s six months they had been living far from their people with Toriel, who got hired as the first teacher for humans and monsters. Frisk lives that forced exile badly, but summer vacations are close enough to go back to New New Home and see all those they left behind.
Soon enough, Frisk realizes something is wrong with Sans. Despite the forced smiles, the skeleton is suffering in silence. Worried, Frisk decides to investigate. Is he still mad for all these timelines they did something irredeemable, or is it something deeper?
One thing is for sure, those vacations won’t be like the others.

Summary
Hope can be a difficult thing in the face of adversity. Hope can be painful.
For some, it's easier to let go of the pain of what could be different and focus on the wall of pain that is. For others, hope is needed to hold back the landslide behind a fragile wall, so they can keep moving forward and make that hope into the reality they want to see.
A very vague summary to avoid spoilers, because this is a continuation of a large cliffhanger in this series. Summary might change as I post more.
**This is NOT a stand-alone fic and can't be read as such!**

A Future Without Them by Baddrummer
Fandoms: Deltarune (Video Game), Undertale (Video Game)

Summary
Years pass. People grow. The world moves on without you. The Angel grew content with that for a while. It still hurt whenever they thought of the world that had long banished them, but something new pulled them out of the depths. Now, the Angel walks amongst friends who swear that they will not be banished. Kris, Susie, and Ralsei mean everything to them. Maybe this time, their banishment doesn't have to be as set in stone as they thought.
The Roaring comes. The light falters. Everyone falls.
A desperate connection is established in an attempt to save what remains of the Angel. If they fall, all hope will be lost. The world that banished the Angel long ago has forgotten them, but they have not forgotten it. This connection will have to be enough. Even if the rules have changed irrevocably, the Angel's one goal remains the same: Find them.

I Wish I Had The Words by EtterathHasFallen

Summary
Everyone knows the local mailman, the one who lives in the dump (not by the dump). And everyone knows he'd rather stay underground for eternity. It's safer, after all. Why bother?
Once an abandoned CRT washes up in Waterfall, Spamton may or may not have to consider a few things. Surely, this warm feeling in his chest means nothing. And surely, Tenna's dream of Surface World fame doesn't involve him. Spamton has nothing to worry about.
Right?

Summary
This is a story about some of my favorite fandoms interacting! This has been years in the making, so I hope you enjoy! This was inspired by Game 6 mainly but also by many other crossover series I have watched/read. Some of them I'd rather not really associate with due to the creator though TwT. Eventually I plan to adapt it into a comic and post it on tumblr, but for now, I decided to write it here on Ao3.
I will likely edit older chapters later, but for now, I have started with the 5 chapters and next month I will post the next chapter and I plan to have one chapter every month.
I really do hope you enjoy and if not, I still hope you have a lovely day!

The Path Less Travelled by TGClmao

Summary
"Two roads diverged in a wood, and I - I took the one less travelled by, and that has made all the difference." ~Robert Frost
Someone familiar falls into a world that is not their own, as the story always goes. Another's path of vengeance left it bitter and broken in ways unknowable, leaving the next to pick up the pieces.
Will they manage with the cards stacked against them, in a world with no real escape?
Only time will tell.
(Though, maybe not. They're pretty tired, and the ghost in their head isn't exactly helping.)

Summary
It’s them.
It’s not them.
“Chara?”
Chara thinks. Clover would get mad if they said they didn’t like it, right? That was rude, it- it was rude. But it just felt so wrong to exist right now. They attempt to stand- sort of expecting to fall over. But they don’t. Clover rushes over.
“Is- is somethin’ wrong, Chara?”
Yes.
“No.”

The curtain has fallen.
An entire world, your world, brought to ruin and ultimately sacrificed for the well beings of a family of grieving gods. Your family.
You are left alone with no hope to hold onto.
You've resigned yourself to this empty life. Left the wishes of those who are gone unfulfilled.
But. Are you really giving up? Will you let this ending be yours? This ending that was forced on you, won't you rewrite it?
The pen is there for the taking.
It's time to go home, Partner. And remember. Stay determined.
