Act as a seasoned steampunk worldbuilder with expertise in alternate-history civilizations. Design a thriving steampunk society where airship travel is the dominant mode of transportation. Describe its [GOVERNMENT STRUCTURE], [TECHNOLOGICAL ADVANCEMENTS], and [CULTURAL NORMS]. Include details like how airships are powered (e.g., [AETHERIUM CRYSTALS] or steam-coal hybrids), their societal impact (e.g., skyborne trade routes or floating cities), and unique challenges (e.g., altitude sickness or sky piracy). Ensure the world feels lived-in with factions like the [COPPER COG GUILD] or the [SKY BARONS]. Use vivid, immersive language to bring this world to life.
