Scorpio (♏) — Fixed Water, The Transformer

Scorpio occupies 210-240 degrees as the fixed water sign, traditionally ruled by Mars and in modern astrology co-ruled by Pluto. The eighth house — Scorpio's natural domicile — governs death, transformation, shared resources, and the mysteries concealed beneath surfaces. Ptolemy assigns Scorpio a cold and moist temperament in the Tetrabiblos, but its fixed modality gives this water an intensity unlike Cancer's tides or Pisces' diffusion: Scorpio's water is underground, pressurized, and transformative. The Scorpion, Eagle, and Phoenix form the sign's triple symbol in esoteric astrology, tracing the arc from instinctual defense through elevated vision to complete regeneration.
