About the the story proposed by Seryan here: https://framagit.org/peppercarrot/scenarios/blob/master/episodes/drafts/the-most-powerfull-magic.md
There is multiple issue:
 Too long dialogs
 Cayenne is a little bit too extreme, but I also like it a bit. Is it possible to smooth her way to talk?
 The ending is weak.
So... what to keep? The start is interesting: Pepper is asking question about Chaosah to Cayenne. Cayenne is asking Pepper to show her most powerfull magic. I think it has potential visually.
