Aethelburg

FOR CENTURIES, THE SURFACE AND THE ABYSS BELIEVED THEY WERE ALONE. THEY WERE WRONG.
Humanity is a fractured species. On the sunlit surface, oceanic platforms like Harpsong Bay and the frozen fortress of Razor Bay battle the elements to survive. Miles below, in the crushing dark of the abyss, the descendants of a forgotten era thrive within bioluminescent, brass-forged sanctuaries like Aethelburg and Veridian. Divided by miles of deadly ocean and centuries of silence, neither world knows the other still exists, until a single, impossible signal bridges the void.
When surface oceanographers Steven and Tanya detect anomalous transmission from the deep, it sparks a desperate mission of discovery. Far below, Malea and Krystal unearth ancient archive codes that reveal a breathtaking truth: their isolated cities were never meant to survive alone. They were built by the same hands, designed to be the greatest of allies.
Now, the race is on to reconnect a broken world. From the perilous descent of the Saltspire Diver to the construction of the Great Artery connecting twenty-four isolated cities, the pioneers of both realms must overcome the crushing pressure of the ocean and the heavy weight of history.
A sweeping tale of discovery, resilience, and hope, this story chronicles the ultimate reunion of a divided civilization, culminating in a triumphant Festival of Lights where the surface and the deep are finally, irreversibly, made whole.
