The "Seven Luminaries" represent the sun, moon and five planets in ancient Chinese, much like the ancient Greeks and Romans referred to them as the Seven Planets. They are also known as the Sacred Seven Luminaries and the Seven Classical Planets which were the seven non-fixed objects visible in the sky.
In Alchemy, the classical planets of the solar system were each associated with one of the seven metals known to the classical world and were referred to as the Seven Planetary Metals. Before you can rule over this puzzle, you must have correctly solved the puzzles for each of the seven metals associated with each of the "Seven Luminaries" - Copper, Gold, Iron, Lead, Mercury, Silver and Tin.
