They go farther, a thousand light-years behind enemy lines to a planet that used to be important. It's no longer the home of the Vestrall, but of a biomechanical race that is little more than drones.

They built and rebuilt the weary and weakened world they inherited, even when it seemed bent on killing them from sheer spite.
