One of the fiercest Daimons ever created, Zephyra lives to torment humans and anyone who gets on her nerves. She only has patience for her daughter and no one else. She was married to Stryker when they were fourteen years old, but he divorced her upon Apollo's orders. She lied that she had miscarried their child, then raised their daughter Medea on her own. Turned out of her father's house, Zephyra took refuge in a temple of Artemis.

Since she didn’t have Apollymi to show her how to live past age twenty-seven, she conjured a demon, intending to sell her soul to keep Medea alive. Once it fed on her, she killed it and discovered that it made her immortal. Since Jared was owned by the gallu she killed, she gained custody of him as well. Her life is tied to Medea’s. The only difference is Medea can have children and Zephyra can’t.

Artemis eventually ordered her to kill Stryker. The assassination attempt brought the lovers back together and they finally reconciled. Now father, mother, and daughter all live together in Kalosis.
