The end of Chapter 1, from page 40 onward! I planned that exposition since the very first draft, when it was a novel, and it was always a tough customer to trim it down to stay engaging but still telling the reader what's up. I'm so happy with the result, even if there's way cooler scenes in the future.
For Zack Dragonblade, it’s Chapter 21, “The Great Split”. Having May learn the truth about her village and having a breakdown was incredibly sad, but also very poignant. She needed the truth to deepen her character and start to grow.
For Erik Grave, it’s Chapter 5, “The Telephone Traveler”. I finally get to open the world a bit and show other mediums, which get to open up all sorts of possibilities for the story.
Edit: I misread this as “favorite chapter”. Ah well.
When you do plot twists, there's the risk that the readers may either already have smelled it from a mile away, or just think: "Ah, OK. So what?" In this page however, a major revelation about Captain Camilla provoked exactly the desired "WTF!?" reaction in the comments! :-D
