The signature
What this decan emphasizes
The storyteller: intelligence becomes expression, warmth, and a social spark.
- The shared sign ruler is Mercury.
- The sub-ruler Sun changes the emphasis without replacing the sign itself.
- Use the decan as a refinement, not a reason to ignore the whole chart.
