Another very cool, and very intriguing perspective! So chaos is at the heart of Mundus? I guess that makes sense; after all, the Daedra Princes and their realms never change. The Daedra cannot be killed, the realms cannot be destroyed (actually, is that true about their realms?). Then again, if Padomay is also a pioneer of change, was Anu one of order and constancy? Or would Anu have changed things as well, just in a different way?
Anu is the primal force of Order, and Padomay that of change/chaos.
If there was only Anu, there'd be nothing but Anu(order). Stillness, un-life, void. However if there was only Padomay, there'd only be Padomay(chaos). Raw meaningless chaos.
It is only through the interplay of both forces that life and purpose can be birthed. In a shell of order (Planet/Body) a flame of chaos is lit (life). Without the order that it takes to maintain shape and forum, there'd be no vassal to carry the chaos which burns like the life within.
Whenever there is too much chaos, or too much order, is when the world turns to ruin. The balance must be maintained. The People/Gods of power do not like chaos or change, because is disrupts and potentially harms their monopolies. The et'Ada were happy with the status quo, allowing the universe to slide into order..into unceasing drudgery. It was at this time that Shor became an agent of change. He convinced, even tricked, some of the et'Ada to do the absurd - to sacrifice of themselves, for something else.
And to that purpose they created Mundus in the Grey Maybe. By fertilizing themselves with the idea of change, they gave birth to Creation. The price they paid was steep though, to become the Earthbones...
Even then the old ideals of Order slipped into their thoughts, as the Aedra became the champions of the Aldmeri they again preached order, control, stasis. Subjection and status quo.
And once more Shor took upon himself the mantle of change; the defiance of the established. With his beloved humans he injected changes and chaos into the world. Short lived men with mighty aspirations and little time to waste, each one a fragment of Shor's purpose, his will.
Meanwhile the Daedra, the infertile and barren, the creation-less, watch from their pillars they refused to surrender. Demanding worshipers, craving followers from the children they never had. The Aedra might have turned upon poor Shor, they might have shattered him for his 'crimes'. But the gift he gave is the greatest of them all, and all those who did not bleed for it.. envy those who did.
