The signature
What this decan emphasizes
The radiant middle: confidence learns to lead without flattening the room.
- The shared sign ruler is Mars.
- 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.

In practice
A more useful question
Where does Aries's fire nature become more sun in your ordinary choices? Look for patterns in how you begin, respond, and recover.
