Element, modality and ruling planet are standard attributes of Western astrology; the personality, keywords, strengths and weaknesses are traditional associations commonly linked to the sign. Decans use the traditional triplicity method (same-element signs sub-rule each 10° third). Compatibility uses classical element harmony (same-element resonance, Fire×Air / Earth×Water complement) — no invented scores or fortune claims. About our data
