(I have waited over six years for the author to update, I accept they have moved on, but like Plato to Socrates, I can not just let this fic die. I wrote most of this cont' like 3 years ago and So I will upload as much as I have done and work from there, deltarune reminded me. not my first time writing a fic but it is my first time writing on a03 so expect issues, I will update formatting frequently. If the original author decides to return I will private this, until then this is my Fan cont' of the work. I hope I was able to recapture the feel of the original)

Summary
The surface has never been the same since monster emerged.
The humans weren’t prepared for the attack and were quickly brought to their knees.
Those closest to the barrier when it collapsed were either killed by the shockwave or were unlucky enough to survive and become feral beasts.
The humans farther out were irreversibly altered. Some grew gnarled horns. Some sprouted animal like tails and fur. Some grew massive fangs and deadly claws.
And some lost it all.
She was nothing but bones and magic now.
Or: Post apocalyptic mash up of the UnderFell, FellSwap Red, SwapFell Purple, and FellSwap Gold universes on the surface where Pitch, a skeleton Altered, does her best to survive and keep hidden along with her growing number of dubiously acquired goat Altered children. But things can only go unnoticed by the Monsters for so long…

Summary

They would spend the rest of his nature life cooped up in an enclosed cell with the wall to keep them company.
OR
Frisk decides to take a one last leap of faith to get even for good.

Summary
Following the end of the war between human and monsters, Asgore, the King of all monsters, sealed the humans under the mountain with the help of seven human souls. Centuries, perhaps even millenia later, the humans, boiling to the brim with anger, complete and utter resentement for their captors, sent up their only chance for their freedom and salvation through the barrier. Frisk, as she's known, is expected to find a way to destroy the cofounded barrier that has kept her people from realising their potentiel.
Yet, any and all plans never survive contact with the enemy. Rather, she meets not vicious creatures who want to eat her whole, but rather a mixture of likeable and despicable characters of all shapes, type and sizes... litteraly. The journey will be long and ardious as she will have to face not only physical obstacles but also some unforseen complications.
Despite all of this, one thing is for sure, Frisk will not come back the same person she was when she left, for better or worse.

Summary
Changelings.
They were the only monsters who escaped the Sealing.
They hid amongst the humans, blending in almost too well.
But humans are clever. They hunted them all down for thousands of years.
In fact… rumor has it that only one survived.
Back underground, changelings had slowly become the stuff of legend, since nobody had seen one for thousands of years. Over time, the stories of their “betrayal” to the monsters evolved into the belief that all changelings were evil, demonic entities.
But now…Inspired by an AU idea from Dawnbie. Made with permission.
