The vibrant sunsets over the Zora Mountains signal the shift from active solar power to battery backups. Breakthroughs in sodium-ion technology and biological photovoltaics have made it possible to fuel the city solely with organic materials from its surroundings, like saltwater and algae. The Zora believe in returning value to the ecosystem rather than extracting from it, so they have created beautiful biodynamic gardens where anything can grow and flourish. The largest of their iconic spherical structures, known as Zorbs, is even said to house the greatest seed vault ever known.
