The Equinox is an old technique of astrology since the Persian/Arabic heyday of reading the stars.
The steps are, beginning with the Ascendant, on 3. 2020 = Sagittarius, stepping12 months = 12 houses. The current month from 12. 2020 - 1. 2021 are ruled by Virgo/Mercury and Pisces/Neptune.
If we know, that Pisces/Neptune = water, so Neptune in Pisces is pure truth, appearing in the inner realm of feeling. As the archetypes in our unconsciousness are covering the whole spectrum, from the best to the worst, they are seizing the unconscious minds as well as they are carrying the conscious ones.
As an occurrence Neptune in Pisces in house 3 = presentation, not only extinguishing the presentation of information, Mercury, as truth as well as lies. Neptune at home in Pisces = the great extinguishment, quasi the pure and total one. Likewise , in the demonic version of the archetypal constellation the extinguishers - the big oligarchs in the background - got to step out of the hiden backgrounds into their truth = Neptune, aka into the foreground of appearance. (Neptune house 3).
Mercury = the information + Neptune's step into appearance are ruled by Uranus' Aquarius (in house 5); Uranus himself is being ruled by the ruler of sovereignty (house 5), the predator Mars.
It is Mars the sovereign predator in state (Capricorn) and society (house 2), together with the ideologue, (Pluto), the universities, (Jupiter) and the corrupted state, (Saturn), swallowing the fifth house of free spirit, Uranus +Venus square Moon, in greed and vanity (Mars + Jupiter).
