Ok, just some of my own ramblings in the very early morning of an insomniacal night.
1) This [Sunbaneglasses' musings] comes back to the inner-Covenant theory, which might work well with the First Chronicles, but is more difficult when comes the Second ones.
"I think the Land represents Covenants body, and various figures The Creator, Foul, Berek etc represent various parts of Covenants mind."
After the First Chrons., he's sent back to the leprosarium, and comes back for ten years of relative sanity -- even publishes seven books. [Berenford:
"For ten years now he's been stable."].
While back in the Land, little by little, the Land is corrupted, eventually being stricken by the Sunbane.
So how then to explain this in light of an inner-Covenant theory? Or is the Sunbane
caused by Joan's decent into madness -- rather than the other way around -- since she's the other side of their covenant/alliance bound by their wedding ring
/edited [spoilered in view of current Runes novel]:
(did she throw away her own wedding ring when they divorced? these come in pairs... )
2) Another of Berenford's comment (WGW, Ch.2):
"He's right about the first one [i.e. first novel]. It's fluff - self-indulgent melodrama."
That can throw some light on the quality of the content of TC's first novel.
Then why was it a best-seller? Popular common-base fiction? (whatever that means) Rosy fairy-tale fantasy novel?
And when TC hears the tale of Berek, with the Queen and King and all, there doesn't seem to be any recollection of his stories into those early legends. So if the Land
is some extension of his own stories, it must have drastically changed quite early on -- even before the Land was populated by men, before the axing of the One Forest, heck, even before the One Forest.
3) Would it be possible that the Creator -- a being that would be independant of TC essentially -- searched for a 'champion' whose life struggles and mentality would be similar and adequate for the Land?
So rather than try to see the Land as an extension of TC by some sort of creative connection, one could 'explain' these juxtapositions not as accidental, neither as a direct causation, but as a choice after the facts, by which I mean something akin to someone placing side by side two stories independently made but with similar themes, for comparison or other purposes.
The Creator then would have chosen someone who
might understand the Land's needs, at least for the
present urgent problem; and who better to understand than someone whose inner- and outer-problems reflected the Land's plight along its historical development -- loss, despair, law, oath, with the ever constant threat of despair/despite, be it in the form of Foul or that of people who don't want you to come to town to pay your phone bills.
(And of course, that person would have a white gold ring.)
This is of course a very 'down-to-earth' 'in-your-face' interpretation -- not a personal favorite by any means -- devoid of that fantastic metaphorical connection between Land and Covenant that I personally love so much, in spite of problems. But nevertheless one can wonder if that is all that SRD wanted us to read.
4) About white gold/ring/Covenant: reading the above, one might say that it doesn't fit with the 'fact' that Thomas Covenant
is the white gold.
We are so certain of this, but where does this come from? Lord Mhoram told TC that he was the white gold. And TC somehow also came to interpret what Mhoram said, taking some force (for lack of a better word right now) from this 'knowledge', not only in the resolution of the First Chronicles, but also in the Second.
BUT: this was only Mhoram's understanding, and eventually Covenant's, and they are limited beings who's opinions might well be wrong, or rather not altogether truthfull/right/adequate,
notwithstanding the success this realisation had on both Mhoram and Covenant.
Did the Creator
ever confirm that Covenant
was the white gold? (And if so, did TC really need to have a white gold ring literaly??)
Is there any indication, other than from mortal limited fallible beings, that Covenant is
the white gold
itself?
Anyway, sorry if all these have been considered before, too lazy for now to read
all that has been said in the Land Dissection years before us newbies came

/edited: and also some of these questions might be moot in view of the Runes novel which I haven't read yet.
