Hydrothia

Hydrothia, the proud founders of hydro-powered technology, is a dazzling marvel of engineering and isolation—an archipelago of sprawling oceanic cities that harness the very force of the sea to sustain their greatness. Built upon intricate systems of pressure turbines, current conductors, and underwater channels, Hydrothia’s cities gleam like jewels upon the waves, their towers fueled by the ceaseless rhythm of water itself. What began as a small experimental settlement in the heart of the ocean has grown into a bastion of prosperity and innovation, where the power of the tides drives not only machines but an entire way of life. Its citizens live surrounded by the hum of flowing energy—vehicles, tools, and weaponry all running on the living pulse of the ocean.

Yet with this brilliance comes secrecy. Hydrothia guards its technology as fiercely as a dragon guards its hoard. While hydro-powered inventions have quietly spread across Thalas, they are often the result of leaks—blueprints smuggled out by rogue insiders or stolen fragments of knowledge that only hint at the full scope of Hydrothian mastery. The true workings of their underwater engines and city foundations remain locked away in archives known only to the highest engineers and governors. To outsiders, Hydrothia appears as both a paradise and a fortress: a glittering empire upon the sea, thriving in luxury yet ever wary of intrusion. Its borders are heavily defended, and its people look outward with both pride and suspicion, determined to keep the rest of the world from claiming the secrets that make their cities thrive.
