Beru

Backstory
Beru, younger sister of Ephyra, was born in Medea, a village near Tel Amot. During her childhood her father was often away searching for Eleazer's Chalice. When a plague came to Medea and killed Beru, Ephyra took the lives of every living thing in Medea to bring Beru back to life. They left for Tel Amot, boarding a boat to Charis, where they were taken in by the family of Hector Navarro.

Beru and Ephyra became close friends with Hector and his brother Marinos before Beru fell ill again and Ephyra accidentally killed Hector's family to heal her. They fled, Ephyra becoming the Pale Hand and Beru becoming the reason fourteen people were killed.

Possession
Near the end of As the Shadow Rises, Beru is possessed by the newly reawakened god of creation that the Seven Prophets killed when Ephyra healed her from the brink of death with its esha. Beru manages to control the god but only barely.
