Story-world rule: the Four Crowns are fictional royal authorities within the series, not claims about real modern nations. Whenever a book enters real history or culture, the exact place, people and period are named and fact-checked. The adventure emphasizes cooperation, curiosity, logistics, science, culture and problem-solving rather than conquest or war.
