Sailing through endless skies, where wind currents turn into invisible rivers, the Hydrovelan travel. Their flotillas of airships and sky-vessels, powered by hydrogen turbines, are wandering cities that drink from the clouds and farm on suspended terraces. They have perfected composite materials and the art of textiles: smart sails that shift with the wind, canvases that capture moisture, fabrics that conduct energy and signals. Descendants of designers, engineers, artisans and poets, they renounced the wars of the ground to embrace the absolute freedom of the air. Their society is a weave of mobile clans, each with its own codes, songs, and technical secrets. For them, movement is life, exploration a duty, and adaptability a virtue.
