Summary
In a Multiverse where Ink and Error retire together after falling in love. Dream is now the new leader of the Star Sans and protector of the multiverse.
With Error no longer a threat, Dream focuses his effort in pacifying the other big threat to the multiverse, his brother Nightmare. In an attempt to cure his brother of his curse of negativity, Dream uses a rather volatile serum from a rather lewd AU.
How will this series of events play out? And how will the multiverse fair without Ink and Error?

Summary
Dark Fountains sealed and ancient malice dispersed, the heroes won the day. But the cost to them is clear, their sins crawling on their backs and the loss festering in what remains of their SOULs. As they struggle to recover from their wounds, with the strings of destiny lying limp in the past, they must choose for themselves who they are and who they want to be. Far from Hometown a lone human girl looking for humanity's lost history resolves to explore a mountain, and winds up thrust into the midst of a story long since over. Will her selflessness help to heal, or will her selfishness only cut deeper?
A sequel set years ahead of the original Deltarune with many themes about gender, healthy (or not) relationships, and kink. Oh yeah it also has tons of hot monster [#$@!] with huge [pipis] and a lot of other [HYPERLINK BLOCKED]
This is the 'all chapters in one story' version for people who prefer that. If you want to avoid certain kinks or w/e the series page can be found here: https://archiveofourown.org/series/2552605

Summary
Life is funny like that, you sure didn't expect to pick up an injured skeleton off a back alley(both metaphorically and physically) only to be sent into a completely different universe with said skeleton and his brothers who seem to just hate you with a burning passion! What follows that? Well more skeletons of course! At first glance they seem like a perfect odd family but is a normal family usually filled with emotionally unstable, depressed, ptsd infested monsters who seriously need therapy and a brat energy check? NOPE ! and just when did you turn into a therapist?!

Summary
As a necromancer, you’re used to suspicious stares and whispers of heresy from the townsfolk. It only gets worse after you’re killed and walk Ebott Empire as an undead skeleton.
When you hear rumors of a strange settlement that worships the undead, it’s too tempting to resist. The locals treat you better than you’ve ever been treated. That is, right up to the moment where you’re dressed up and tied to an altar as a sacrificial bride for their skeleton gods.
Despite their advanced technology and magical prowess, you’re doubtful of their divinity. What kind of gods blush whenever they see a bit of bone? -
