(Has been rated #1 in Frans more than 10 times since April 2018) 
It's 210x, and nearly eleven years after Sans' " ignorant " deed. Little did anyone know it would be the year when the human has mysteriously fallen again, though the  seven human prophecy had supposedly been fulfilled. "Seven humans shall fall... Only one will enter and exit alive." 
By this time Frisk is a growing young lady and Sans is a young man, now working as head scientist for the royal family, along with Gaster and Alphys as his assistants. He is more than happy to see his old friend and she is welcomed with everyone's opened arms. That is...Until she is proven to be something a little more than she appears to be.... 
Join Frisk as she slowly uncovers the underground's forgotten past and her own dark side, hidden deep behind her DETERMINATION.


((This is an original AU by EkoingSkies. Warning! The main ship in this is Sans and Frisk! If you wanna read this, be sure to keep that in mind. This is my first book, so I would love to hear your interpretations of it!

What if there was an anomaly in the Underground? No, not Frisk. Not Chara either. Someone else entirely. How could a few measly children stand to this supposedly immortal foe and save the Underground from destruction? Is it even possible to do so? Only one way to tell... ~o0o~ Disclaimers before you start! •There is NO fanon ships. That means no Soriel, Papyton, etc. The only ships are Torgore (in the past) and Alphyne. •This is NOT an x reader. I heavily dislike those types of stories. The reader will have no part in this. •This exists outside of canon to an extreme. For example, Frisk is the second human and not the eighth. •There will be OCs, but only for a few humans and they still technically exist in normal Undertale. •There is a sequel. I'm planning on rewriting it after this one, as it is much more random and definitely needs it. Clanky, plot holes/retconning, etc. It's more of an OC thing, to explore them and their issues, than an Undertale thing, but it has its similarities. •There will be some explicitives. It won't be unnecessary or excessive, only when it fits the situation and character. I will not be using any slurs, as that's just plain disrespectful, even if some of them apply to me. Credits: Undertale, obviously, created by Toby Fox and Temmie Chang. "The Time Before" by ANinnyMouse42 is the backstory for Sans in this AU with some adjustments (mainly since that was very close to my original idea before I read it and I don't want people to think I copied their masterpiece or smth, if you haven't read it please do so, it's really good). Some things will be in reference to the other books in the trilogy or "From War to Science" by Emotistic-optimistic. If you haven't, read that too. It's really good (along with its sequel). The cover was made by me! Have a good day! (Also, the title is a placeholder, if anyone has any ideas that make more sense, please let me know. I do have some ideas, which are going to be mentioned at the A/N of C

(I DON'T OWN UNDERTALE. The only characters I own are Bailey and Creame.) All the monsters live happily in the underground: until one human ruins everything. Bailey Hill is a normal, 11 year old girl- until she trips, and falls into Mt.Ebott. Quick to befriend the monsters, Bailey is instantly loved by everyone. When monsters start mysteriously disappearing, Bailey is on the case. What she doesn't know, though, is that a small team, co-led by Undyne and Sans, are working as secret spies in the background. After hearing about the disappearances, Bailey thinks she can solve the mystery- but when Bailey has a shocking realization, she realizes that she might not be so innocent after all. ------------------------------------------- Changes: IMPORTANT: Frisk and Chara don't and never exist(ed) Monsters don't mind the underground, so Alphys never did the experiments. Still Relevant: Mettaton never left, and Napstablook is constantly being featured on his show The amalgamates don't exist since those monsters never fell down. Napstablook and Shyren are now younger than in-game, Napstablook - 12 and Shyren - 14. More on Napstablook- Since Mettaton never left, Napstablook is just shy. Everyone knows each other Alphys x Undyne- Already a couple Frisk and Chara don't and never exist(ed) ------------------------------------------- A note from Emma- Hi hoomans! I hope you enjoy this AU I came up with! Happy reading! 😊 10/4/2020: There IS a sequel coming soon! :D
