There is a constant battle between the light and the dark. The dark energy consumes the light energy and the light energy consumes the dark energy. They are both constantly fighting each other for energy. The twelve angels in the collection represent the twelve zodiac signs which are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. As the Earths energy moves through the energy of each zodiac sign taking a total 25920 years to complete a full cycle the level of consciousness the Earth and human beings experience increases and decreases. These cycles in these levels of consciousness are known as the Iron Age, Bronze Age, Silver Age and the Golden Age. The dark is at its most powerful during the Iron Age and the light is at its most powerful during the Golden Age. The dark levels of consciousness act as a triggering mechanism to increase the light levels of consciousness, ultimately they are both as important as each other.
