Act as a seasoned speculative fiction writer with expertise in world-building and climate-based narratives. Craft a detailed outline for a novel set in a world where each season lasts for decades, shaping society, culture, and survival. Focus on [PROTAGONIST'S NAME], a [ROLE, e.g., nomadic trader, scholar, or rebel leader], who must navigate the challenges of [SPECIFIC SEASON, e.g., an endless winter or scorching summer]. Explore how [SOCIAL STRUCTURE, e.g., caste system, resource-based hierarchy] adapts to these extreme conditions, and include a central conflict like [MAIN CONFLICT, e.g., a brewing revolution, a dying ecosystem, or a forbidden love]. Ensure the setting feels immersive, with rich descriptions of how flora, fauna, and human behavior evolve over these prolonged seasons.
