Ok, now to address Griff's points directly.
Transplant complete!
1) Is each Mantle an individual Aspect/Aeon?
I liked using the term "quasi discrete" because they still have ties back to upper tier Aspect/Aeon and to their sibling (for lack of a better term) Aspect/Aeons. Sorry that's kind of a non answer...
2) Clearly Vadderrung has two different Mantles, and they remain separate from each other. They don't seem to manifest at the same time, but they're held by the same being. Is their compatibility due to their varied nature, and the WK/SK incompatibility due to their similar, opposing nature?
Interesting question. I actually have a side/related theory that the Odin/Kringle duality was needed because when Mab took over at the Outer Gates the action offended (I am a fan of the theories that the Aesir were the guardians before the Fae). The duality ended up becoming necessary to allow a pissed off Odin to set that grudge aside when necessary by putting on a faerie hat of his own. Thus when it comes time to take care of business that reality hinges on and stuff, he has a tool in his toolbox that makes that possible.
"You're here as Kringle, seriously?" I asked him.
Kringle winked at me. "The Winter Knight called for me in his official capacity as an agent of the Winter Court. Mab has the right to summon Kringle. If she'd called for Vadderung, I'd have told her to get in line."
[/snip]
"But you and Kringle are the same person," I said.
"Legally speaking, Kringle and Vadderung are two entirely different people who simply happen to reside in the same body," he replied.
"That's just a fiction," I said, "a little game of protocol."
"Little games of protocol are how one shows respect, especially to those with whom on does not get along famously well. It can be tedious, but generally is less trouble than a duel would be."
So either the powers that be allowed a little bit of Fae Power to get fashioned into an extra bit of mantle to placate Odin for whatever causes him to not get along famously well with Mab over, or Mortal Belief provided the framework for that odd bit of duality, or Odin sliced it off himself on Halloween or some such to please his own needs, or some combination of those... but somehow he got it, and it sure seems to suit his purposes when he wants.
I'll post this and then start editing in my responses for the rest of your comments.
3) Are human Souls a Mantle? From a certain viewpoint, a mortal shell/being is given an immortal power source to use for a time, and when the shell dies, the power source departs, continuing to exist elsewhere. Its almost like a Mantle, albeit not apparently reused, at least in some beliefs.
Hmmm, deep. And apparently the kind of question the gnostics loved to examine. In fact, I believe for some of them, they believed that upon death, the soul was finally released from the imperfect and impure mortal reality and was finally allowed to reunite with the upper levels of existence.
So I'd say this certainly seems like a valid interpretation of GUCMT, but that we can't really be sure of the true nature of the soul.
4) If a Soul is an Aeon/Aspect, then wouldn't it mean that it would remain separate from the Mantle, and not be destroyed? There's been speculation by some that a host's Soul is slowly absorbed by the Queens Mantles, merging with them. But the Aeon/Aspect theory combined with the dual nature of Vadderrung's Mantles would imply that Aeons coexist and remain separate. Would that be the same for Souls, or are those Aeon's too weak to survive alone? I think there was a WoJ talking about how Mab lost her Soul. Did it just move on, since the Mantle Aeon pushed it out?
Hmmmm, I know you are familiar with
WoJ #14 which is the best I have for answering this train of thought. I think a better analogy for what may have happened to Mab's Soul would be that it withered and died due to maltreatment/malnourishment or something...
Interestingly, we have a WoJ that the fundamental reason why Harry couldn't have ended up with Maeve's Lady mantle isn't just that he isn't the right gender, but because as a vessel for mantles, his is too full. I'll have to add that to the multiple mantle section of reply #2.
5) So Mister is Ferro? j/k
6) Seriously, why hasn't Harry used Mister in a joke yet? "Mister Dresden?" "Mister Dresden is my cat. Call me Harry."
How have I never heard that one before? Hillarious.
7) Could the inherent incompatibility of the W/S Mantles be due to the fact they were one Aeon/Aspect, which was then unnaturally divided into six/eight, rather than "pooping" out sub-Aspects? And if re-merging the WK/SK Mantles is such a bad thing, wouldn't it have been almost as bad for the SK Mantle to go to Winter in SK? For that matter, any of the six/eight Fae Mantles joining with any of the opposing side would be bad.
I spent some time answering this in the multiple mantles section of Reply #2. I think I came up with an excellent response.
Souls are the perfect memories and sums of the lives they've led. But the mortal isn't aware or familiar with that perfect knowledge, nor even sure of its existence. Could the same be said for the Mantles/Aeons and their hosts? Upper echelon Aeons like Uriel might be self-aware of their Aeon/Aspect power and existence, explaining their inability to act; becoming aware of the situation in some way would limit their interaction. The Queens are partly aware, on three different levels, which allows for them to interact with events on three different levels. Mortals, being the least aware, are free to act.
I'm not sure what I am supposed to be answering here... Generally for GUCMT, it seems that the more powerful the being, the more reality spanning, and more aware of their spanning of the reality spectrum. I do like how this ties the non wetware storage of mortal experiences to GUCMT though. I would say that the more powerful beings (I'll use that term for Mantles/Aeon's and their hosts together) apparently have access to this data storage. Either by watching it play across a Ghosts being, or some other means like with Lasciel's shadow.
Interestingly enough, a freaking Soul Gaze does this. That's right a Soul Gaze ties neatly into GUCMT. In fact, the Molly Soul Gaze is a perfect example of how a Soul Gaze can look across possible future realities to show how her decisions could result in her becoming a different person. And it gets etched into Harry's memory.
9) In that sense, the whole purpose of mortals is to be the foot soldiers and pawns of upper level Aeons. Since they are unable to act, everything has to be fought on mortal plane. Obviously some battles are on other planes, like the Gates in the NN, but the eternal struggle between the two Poles is not fought at the wall, but on Earth. The wall and Gates are simply to keep the game board from being overrun.
10) How does corruption play into the Aeon/Aspect theory? If TWG is one Pole, or so high/close to the 'Order' Pole that Its practically the same thing, then everything It created/"pooped" would be a lighter/ordered Aspect like itself. But clearly higher level Aeon/Aspects can be corrupted, like Lucifer. Luci should have been very high up on the Lightside, but Fell to the Darkside. Was that corruption due to something like Nemesis, or an inherent ability of Aeons/Aspects to change?
Meh, this gets kinda deep, and I'm not sure if I can address it. In the Amber Chronicles, it becomes an issue that at one point there was only one pole, and a prince of that pole actually struck out across reality and established the other pole, and somehow that act is what instituted all other reality. And part of the nature of the original pole is the need to destroy and subsume the opposite pole. But wait, if that were to happen, all reality would be destroyed. But then how could it have been established in the first place. And the egg and chicken need to be destroyed (that's me taking the conundrum and getting silly)
So maybe things weren't interesting until the "Fall" anyways. And maybe because they weren't interesting, they were unstable and the "Fall" was an inherent characteristic of this instability.
I'm not sure where corruption comes in in this, although in the Amber Chronicles, there was a major plot line where the Chaosians cut the crap and blazed a corrupted trail across all reality in an attempt to assault Amber directly.
And that I am not limiting my internal model to a binary duality of the universal cosmic forces like in the Amber Dipole Model.
Time to walk the dog, I'll edit in more responses later.
11) In SG, Uriel gave up his Grace, which in this theory, would be the equivalent of his Aeon. Had Michael acted poorly while wielding it, what would have happened to the Grace/Aeon? It doesn't seem like an Aeon could be destroyed, so it would have to go somewhere. Would it simply Fall to where Lucifer and the other Fallen Aeons are kept? Would Uriel remain a mortal, bearing only a mortal Soul? Would he have no Soul? And what about Luci? When he Fell, did he take on a mortal form, to live out his days as a human, and his Aeon/Mantle/Grace was put away in a lockbox? Or was did his Soul remain with the Aeon/Mantle/Grace?
Hmmmm, well seeing as to how it was a Mortal who would have made the critical decisions, it might only apply to the local reality or set of realities. Or since it's involving such a heavyweight "Aeon" it might span a lot more if not all of the reality spectrum. As to what would have happened to the mantle and Uriel, I suppose that would depend entirely on how things shook down. Which means Jim would have to write it and see.
As for Lucifer, I think he didn't split from his mantle. The Angelic mantles are a little odd to me... Are Rafael's lieutenants emanations of himself, or were they created from whole cloth when Rafael was created by or emanated from the Creator? And thus could Lucifer poop out sub mantles like seems to have happened to the Fae left and right.
The best example we have of "lesser" fallen effecting the mortal realm are the Denarian's who apparently fell along with Lucifer, and then much later in some major turning point event (probably hinging on Free Will, like the choice to betray the White Christ) they were bound to the Denarian coins and thus were apparently cast out of Hell, but given a measure of influence over the mortal realm.
Oh. Hey look at that! We have a rather recent example of one of those emanating out a hybrid aspect with a relatively significant Mortal. And hints of something similar happening in the past (Bob).
12) Is it the Soul that can be corrupted, rather than a higher level Aeon/Mantle/Grace? Do all beings, high and low, have a base ingredient Soul, which can be manipulated? And that Soul is what causes higher beings to Fall? In theory, to be mortal, Uriel would have to have a mortal Soul. If he had one, then Lucifer should have too, right? So is that Soul still tied to the Aeon/Mantle/Grace of Lucifer wherever it is? Is that twisted Soul what is causing the Grace to act out of character? And if it were separated, would the Aeon/Mantle/Grace appear to be corrupted/Fallen, or would it return to its normal Lightside state?
Hmmmmm... I'm not sure what to say about the Soul/Mantle comments other than your pointing out that Uriel seemed to be able to differentiate between his Grace and his personhood(soul?) which is good evidence that they were separate.
I will say that nobody seemed worried that the nemfection would pass from Maeve to Molly with that mantle though... Heck... ok with that perspective we might be able to make some applications of GUCMT... We know the cosmic powers can't change... Although how they manifest or are understood can change. And Per GUCMT, part of how they manifest is the emanation of Aspects. Mostly it would seem that those Aspects/Mantles only change in how much influence they end up having due to Free Will choices, and they probably can't change much without getting reabsorbed back into the upper echelon Aspect first, although that isn't a sure thing... Still if we assume that, and we assume that Archangels have personhoods that can be held distinct from their power/Aeon/Grace/Mantle, then a Fallen Angel's internal change and corruption is probably only only associated with that distinct personhood, and not the actual Mantle itself.
Which isn't to say that the power of the mantle isn't now being used by that corrupted being for some gawd awful stuff. A hammer can be used to build a house or bash heads in.
13) Or did Uriel separate himself from his Grace on purpose, knowing that if he Fell, the Aeon/Mantle/Grace would remain unblemished, while only his mortal Soul would Fall? If so, is the issue with the Fallen that they didn't separate from their Aeon/Mantle/Grace before being corrupted? And is that corruption in both Soul and Grace, or only the Soul? And would both need to be redeemed, or only one? Clearly Uriel could separate from his Grace, but maybe he couldn't have separated Lucifer from his; its a decision of Self. That would mean that if the Soul of Lucifer decided to relinquish its hold on its higher level Aeon/Mantle/Grace, would that power be restored to the Lightside, and could it be re-assigned to a new Soul? A new Lucifer, on the side of good?
Sorry, I've spent enough brain power on the angelic grace angle today... *fzut* *sputter* *kaput* overload, no more no more.
14) Taking it the other way, are the Outsiders upper level Aeons working without Souls, which is why they can't exist or interact with the mortal plane? They should be restricted from reality, and unable to work there, just like the other Aeons. But their nature is Chaos, from the other Pole, and therefore not following the rules is their natural state. So if they get through, they would be pure Aeons existing where they shouldn't?
No clue sorry... My best attempt at interpreting the Outsider role, is that they could be from a separate reality spectrum subject to a totally different form of splitting regulated by something only mildly related to our concept of Free Will.
I am just now reminded of a WoJ I think I heard in the past month or so that I need to hunt down...
