Azir
From Marillia
Azir, often known as the Demon, is the chief adversarial figure in the Lucianus.
Meta
Azir is referred to as "the Demon" in roughly the same way that Satan in the IRL Christian world is referred to as "the Devil."
Identity
Some Lucian theologians claim that Casir (the Saphorite god of the desert) and Ahuraiya (the adversarial figure in Mazdana) are guises of Azir.
