Yea elune seems to be something akin to a void lord (void god?) but on the side of creation.
I find it curious that Naaru magic is often pure yellow light akin to the Sun, but Elune always uses the blue moonlight.
Her constant ties to the Moon is what i find interesting... why Moon and its light specifically?
Moonlight is, in our universe, the sunlight reflected upon the moons surface.
What if Elune herself is a reflection of something?
Perhaps she is something between a "void lord" and a "light lord"?
Either a mix of both or perhaps in a phase where she moves from one side to the other, similar to how naaru can change between light and void?
