The problem is that she is atm a canon deity in the sense that she answers to no higher will other than her own. Naaru follow a cosmic force with no defined leader. Elune is unrestrained and is related to multiple alignments: arcane, light, life, and shadow/void magic. There is also no other known equivalent to her.
I guess loa/wild gods could be considered deities too, but I see them primarily as spirits/lesser deities at most.
