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.
