@cfusion25 they received other useful information at the start as well. The first chapter stated some unnamed weakness, The second was a powerful weapon's location, low guard count on wednesdays in the 4th chapter, and prefered terrain in chapter 7. All of this is useful information.
@Granitefish The "preferred terrain" in Chapter 7 wasn't about terrain at all, she just meant that the King likes Tokyo Disneyland more than Disneysea (although I have no idea who in their right mind would)
