Draconic astrology — the 'soul chart'. The tropical zodiac re-zeroed on the Moon's North Node: draconic(λ) = (λ − North Node) mod 360, so the node becomes 0°00′ Aries (☊, the dragon's head) and the South Node 0°00′ Libra (☋, the tail). Read as the SOUL layer beneath the incarnated personality of the natal chart. Because it is a rigid rotation, the draconic chart's INTERNAL aspects equal the tropical chart's exactly — so the real signal is the draconic→tropical CROSS-aspects (a bi-wheel overlay): a draconic planet conjunct (or opposite) a natal planet/angle, the headline being 'draconic Sun ☌ natal Sun' (soul and self aligned). From birth date/time (+ optional place) it returns the 14-factor tropical+draconic table, the draconic chart, the cross-aspects (graded exact ≤1°/strong ≤2°/close ≤3°, conjunctions & oppositions first), the same-body soul contacts, a whole-chart-shift signature, and a 0–100 soul–self integration score (NOT a fortune). Mean lunar node (Crane's foundational work prefers the true node — a ≤1.5° difference); factor longitudes share our natal ephemeris so the tropical side agrees by construction. Honest: this is a re-zeroing of the TROPICAL chart, NOT sidereal astrology; the soul/karmic/past-life framing is symbolic, not an empirical finding. Locked against published draconic charts (Atwood, the Australian Academy worked example incl. wraparound, astro.com) and the defining invariants (North Node ≡ 0° Aries, South Node ≡ 0° Libra).
