Theia

Theia is the Amestrian name for Cybele, the only currently known planet in the universe of Clymene (see also: Aion). The name's cultural origins and meaning are so broad due to Savoy's need to appeal to the various cult-based religions found throughout the empire.

The name is derived from the ancient Greek deity Theia, the goddess of sight and the shining light of the clear blue sky.
