Athenas is Maya's planet of origin. According to ECHO Recorders obtained by Angel, the planet is ruled by a monastic order known as the Order of the Impending Storm. When Maya was left with the Order as an infant, the monks raised her and used her reputation as a Siren to scare the populace into obeying them for 27 years. When Brother Sophis, a leading monk of the Order and Maya's caretaker, attempted to force Maya to execute several 'criminals,' she realized the Order's deceit and killed Sophis. Maya then left Athenas to find answers about her heritage on Pandora.
Between the events of Borderlands 2 and Borderlands 3, Maya returned to Athenas to learn more about Sirens and to protect the Order. She would eventually find and train Ava as her apprentice.
