That reference to "mother" in regard to the earth/land is common throughout the series, so I lean toward this theory having some merit. From early on we see that the Creator doesn't take an active role in the vast majority of things that happen (sort of like the theory about God being like the clockmaker who winds the clock [earth] and then leaves it alone to run), but there IS that voice in TEotW and so to me there HAS to be some sort of follow up from the side of the Creator. And in keeping with the theme of balance, the Dark Lord is referred to as male (even though he is not really of either gender) so I feel like the Creator should be represented by a female (again, even though the Creator is not of either gender). It just FITS, at least in my mind. All I can say it, there BETTER be some additional answers about Nakomi in the forthcoming encyclopedia or I will NOT be happy.
