“Everyone has a Function. Only the privileged are allowed a Purpose.”

Beneath the surface of the dying planet GTC-4B lies Echelon, humanity's last great civilization—a colossal underground city powered by a failing geothermal core. Here, society is divided by altitude: the wealthy live in artificial sunlight and luxury, while millions of workers spend their lives maintaining the machines that keep everyone alive.

You are one of them.

A routine shift in the industrial Depths leaves you with something you were never meant to find: a dead government researcher, a mysterious executive credential, and fragments of information about a project called the Ark.

Soon, a revolutionary is asking dangerous questions. Your childhood friend is caught between the world you came from and the world above. And one of Echelon's most powerful administrators has taken a personal interest in you.

The geothermal core is failing. Someone is preparing to leave.

And there won't be room for everyone.

Will you fight for freedom, secure your place among the survivors, expose the truth, or simply try to survive long enough to choose?
