The signature
What this decan emphasizes
The inventive analyst: systems are examined, questioned, and redesigned.
- The shared sign ruler is Saturn and Uranus.
- The sub-ruler Mercury changes the emphasis without replacing the sign itself.
- Use the decan as a refinement, not a reason to ignore the whole chart.
