(2) Hrrrrm. I see there is indeed the implication of a single, dominant Achura Empire. Ah, well. The tendency to treat entire planets as single countries marches on.
... Wait. Reversing that last grumble, could it be that only one, mid-sized continent on Achura had a civilization worthy of the name at the time?
(1) Considering the infrequency with which the Creator is mentioned elsewhere, maybe we shouldn't consider the Achura monotheistic? The Creator is surely a god, but need he be the god, or even the most important god? Hindu belief is ... complicated, but sees gods within gods within gods (from certain points of view). Buddhist thought allows for the existence of gods, but considers them a part of the world of illusion-- something to be transcended. Taoism, at least in its folk variant, virtually allows for apotheosis.
(Taoist "outer alchemy" involves trying to make yourself an immortality pill-- typically out of cinnabar, which, being as it's essentially mercury, will help you abjure the flesh, all right.)
Anyhow ... as a thought, considering the number of Achur sects, why confine ourselves to one creation myth? There could be dozens.
As a thought, the rod could be presented as a metaphor for the wholeness of the Totality-- in creating the universe, the Creator himself shattered the rod. By breaking the rod, the holistic oneness of the universe was shattered, and disparity came into being. Some sects might regard this as a story about how the divisions that define the universe came to exist. For others, such as the Shuijing sect, the disparity isn't real, and the rod is truly whole-- but only someone who can see past all illusions can see that!
In that case, "To see the rod broken" is to be lost (along with just about everybody else) in the illusions of the world. "To see the rod whole" is to achieve perfect insight into, and unity with, the Totality.
