The Underworld Engine: 
The Core

The world did not end.

It evolved.

Far beyond the age of humanity, the Underworld Engine continues its eternal work. Souls flow through forgotten systems. Ancient cities sleep beneath forests of crystal and steel. Machines dream. Gods linger. Something waits beneath it all.

Your are Corte.  Your memory lost.  All you can remember is your name, and a woman's voice..  

Awakening within the Shallow Growth Cradle, a strange nursery where souls are cultivated and reborn, you begin a journey through the ruins of a world that no longer remembers its creators.

Explore vast interconnected regions, battle corrupted entities, discover lost technologies, and unravel the mysteries hidden within the Engine itself.

Every path leads deeper.

Every answer raises new questions.
