Hellen was a Delphic priestess who was wed to Stryker in a marriage arranged by Apollo. Their loveless marriage produced nine sons and one daughter. She lived in Kalosis for as long as she could until it was too dangerous for her as a human surrounded by hungry Apollites and Daimons. She moved to the mortal world and began a relationship with a human man named Memnus. They were both slaughtered by anti-Apollite humans.
