The signature
What this decan emphasizes
The generous horizon: action becomes faith, courage, and a larger quest.
- The shared sign ruler is Mars.
- The sub-ruler Jupiter changes the emphasis without replacing the sign itself.
- Use the decan as a refinement, not a reason to ignore the whole chart.
