When a system achieves system light and life, Planetary Sovereigns join the system conclave, forming a self-governing administrative body subject to the Constellation Fathers' veto, with a system legislative assembly on the headquarters world and courts on each planet's capital. [1]
Upon the inauguration of the era of light and life, the Planetary Princes are elevated to the position of Planetary Sovereigns, marking the culmination of their service and the beginning of a new order of world administration. [2]
The Material Son and Daughter are the visible rulers, while the Prince-Sovereign is only seen in the morontia temple, making them the true heads of the planetary regime. [3]
