You are free to make fan-made content for Deltarune: Beyond the Prophecy. I want people to be inspired, but not restricted by it being an AU made by me. In this game, you have taken the Normal Route. You have also fought all secret bosses and found Starwalker. The armor you have equipped upon starting is the "Ultimate Mantle." It is the final Secret Boss item when you fight Seam in Chapter 7. The Vessel has not been found yet as of Chapter 8, but you have met Gaster. Kris' motivation for opening the fountain was to prove the existence of Dark Worlds to Undyne. Chapter 3's main boss is "Castle." (chapter 3's secret boss is Tenna) Here is a list of all the main bosses. (and secrets)

Chapter 4: None - None

Chapter 5: Bishop - Darkhorne (The Darkner of Kris' lost horns)

Chapter 6: The Knight (Carol Holiday in this AU) - The One (A failed experiment from Gaster)

Chapter 7: The Roaring Titans - Seam (seam)

Chapter 4 has no dark world, Chapter 5 takes place in the church, Chapter 6 takes place in the bunker, and Chapter 7 takes place in Hometown. Yes, you have met Dess.

Here are the dark world names and themes:

Chapter 3: Homeworld (tv, what do you think?)

Chapter 5: The Holy Land (books)

Chapter 6: THE PROPER (a pure fountain)

Chapter 7: Metropolis (festival)

Bye!
