A major mining Age written by the D'ni people. D'ni machines were established there, ran by natives.

In 4334 a native made a mistake operating the machinery and the Age was halfway destroyed. Families were forced to evacuate and, in one particularly odd case supposedly a child was born while his mother had been linking back to D'ni City; that child was the Watcher.

The destruction of the Age was another cause of argument for those who wished to seal themselves off the Outsiders. King Loshemanesh argued that the accident could have happened regardless of who was running the machine.[1]
