"This powerful ability is only possible for advanced civilizations with high concentrations of population. Caused by harmonic waves that are amplified when the entire surface of a planet is developed by members of the Harmony, it provides powerful boosts to the production of Food, Industry, and Science."
"Minerals are known for their unusual affinity for and reaction to certain forms of waves. When a planet is fully "harmonized," the living minerals of the Harmony can instigate a form of particle vibration that coheres the citizens and their daily activities via a system-wide series of grids. The primary role of these grids is to restore a part of the powers that the Harmony lost when they encountered Dust."
