Why did I choose Astraea?

Astrea was the code-name that Aphra Behn uses as hers when she was working as a spy for Charles II. During the war with the Dutch, she supplied information to the English government. When she returned to England she was taken to jail briefly for debt.

In Greek mythology, Astræa or Astrea (Ancient Greek: Ἀστραῖα: "star-maiden")was Zeus and Themis's daughter. She was, as her mother, a goddess of justice.
