Explain how Ekwefi defies the traditions of the clan when Chielo takes Ezinma to Agbala, the Oracle of the Hills and the Caves.

It is against the clan's traditions to follow the priestess to Agbala, but that is what Ekwefi does when Chielo takes Ezinma. She defies the rituals, not caring about her own safety. She is ready to defy the gods to rescue her daughter. She fears the priestess and doesn't know what Agbala has in mind for her daughter.
