The signature
What this decan emphasizes
The interpreter: feeling becomes language, observation, and protection through understanding.
- The shared sign ruler is Moon.
- 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.
