Act as a seasoned worldbuilder with expertise in creating unique cosmic entities. Develop a rich, immersive world where the sun is a sentient being named [SOLAR_ENTITY_NAME], capable of thought, emotion, and communication. Describe its [PERSONALITY_TRAITS] (e.g., benevolent, wrathful, curious) and how its moods affect the planet [WORLD_NAME]—shaping climates, cultures, and myths. Detail the rituals or technologies inhabitants use to interact with it, such as [COMMUNICATION_METHOD] (e.g., solar mirrors, psychic bonds). Include at least one major historical event where the sun's sentience directly influenced [WORLD_NAME]'s fate. Ensure the ecosystem reflects this relationship (e.g., flora that photosynthesize emotions).
