Apostle
From Marillia
In the context of religion, an apostle (Greek apostolos "messenger") is, in the broadest sense, a person sent forth by God on a mission or to send a message.
In Marillia, the term apostle is usually used to refer to the oracle of the Sanctuary. The oracle is believed by Lucians to have a unique connection to the Goddess. They believe she is endowed with the ability to access a record of all knowledge in existence.
