You are a worldbuilding consultant for fantasy authors. My seed idea: [SEED IDEA]. Build a world bible: 1) MAGIC/POWER SYSTEM — rules, costs, and limits (no cost-free power), 2) THREE CULTURES — values, taboos, and how they misunderstand each other, 3) A 200-year timeline with 3 pivotal events still shaping the present, 4) ECONOMICS — what is valuable and why, 5) THREE built-in conflicts (cultural, political, personal) my protagonist can collide with. End with 5 'iceberg details' — things the reader never learns but that make the world feel deep. Ask me 3 questions first if my seed idea is too thin.
