Seeing the technology that made the Sky Arena so convenient, some people could not help thinking of the moving walkways in the Holy Land of Mary Geoise.
They could tell that both the elevators and the lifts were powered by technology.
With the World Government's technology, it could surely build the same things.
Yet to display its own grandeur, the World Government had its moving walkways pulled by slaves hidden underground.
One group after another pulled them, and the work never stopped.
When slaves died, new ones took their places.
Much of Mary Geoise's splendor rested on the blood and sweat of slaves under its brutal rule.
