Neptune became empowered when the Sun entered its sign Pisces at the moment of her birth, lessening the thrall Saturn acquired over that planet when it ingressed into Capricorn five days earlier.
That there are no planets in the hemisphere between Jupiter in Aries and Pluto in Scorpio, whereas in classical astrology asteroids are omitted to avoid clutter, means all activities and subjects portended by those houses and signs is absorbed only thru secondary relationships, ie dispositors! The Jupiter in Aries figure is a great hulking brute who guards her back, while the Pluto in Scorpio placement alone in great power adds a degree of sexuality to the whole.
Mercury in Aquarius inclines the nature toward more elevated thought patterns, and provides a stable emotional environment that compliments her Pisces Sun, as well it sees humanity as a whole neither despising other's aspirations, nor sacrificing her own principles for worldly favor.
Despite it remains on Saturn's terms, it brings independent means and causes constant rebellion against the Saturnine presence, that insists she be part of the fold Uranus which has its own power base guaranteed by the placement of Mercury in its sign Aquarius, is similarly on Saturn's terms in the first degree of Capricorn, Mars in Sagittarius the sign of Jupiter's rulership, in mutual reception with Jupiter conjunct Venus in Mars' sign Aries, super powers her 'scope.
