OMG.. Blackthorn I thought about this all night and I came up with the same thories you did the 2 opposing pyramid's symbolize the Element and Balance principle, and of course the fire burning round them is a clear indicator of the element principle to me, and they are balanced on one another.. , that one was a no brainer.
Another thing I want to interject her is that I think we all want to make this harder than it has to be, if we just stick to the simple facts we can stay focused on the problems at hand.
And to me the whole of Mt. Kelle'tha represents the Book Of Principles in exactly the way you have described it. All this conjecture of moving pyramids, bringing the floating pyramids down to get at the fire for reading so called invisible words on the pages, catapulting anyone of us up there, walking into the flames..ect.ect. is not needed to find the book, I think we do not need to find the book..it is not there as an object to find, hence the wizards reamarks about sending Akasha in the first place. But I do think the book is there and with the wonderful imagination (principle) of us all, from first incorporating the principles into the MagicDuel game, structuring an evolving game to use them in the creation of magic into the game, having 2 key players seeking the Book of Principles, all this and so many more thoughts turned into actions, all play together with the Principles all involved in it....to create this book from it. And really when you think about it the book is allready created the Principles are all ready there, but just have to be bound in a book and the desire for that has come to being.. .
There is one more thing I want to interject into all of this, since the Transposition Principle was the one I am supposed to be exploring..and really it lead me to this train of thought also. Understanding the idenity of a individual of object, when I started to do that about Mt. Kelle'tha it brought it all together for me. This place is obviously a very holy place..hence all the altars, the magic of the floating pyramids, the slow burning eternal flame, the desire for magic and knowledge of that magic spurred in all of us, the almost irresistable urge to explore that and to acquire that magic and knowledge of it. All this plays perfectly well into the Transposition Principle..understanding the place to begin with, using how we understand it and giving those qualities of understanding to an object and to ourselves. As I understand the Principles as a whole and on there own more and more it is not the Principles by themselves that are magic it is how we use them together that creates the magic for us! And as magic is and of in itself a holy premise what a more perfect place for it to be born than Mt. Kelle'tha.
Now I do have a theory on how the book will look, not that it really matters, and since I don't know how to draw on this thing..sad I know..lol... so will explain .. 2 triangles bound together on the bottom edge of the so called pyramids, so it opens up to form the diamond shape of the 2 floating pyramids on Mt. Kelle'tha. Reasoning for this is the amount of pages found 6 isn't it..5 for the principles front and back used, and the remaining 1 page torn from coner to corner to form the bindings of the book, I am not sure about this but didn't Akasha say that one of the pages was torn on the corner..sorry I need to check her story for me to be sure about this.
Ok this is all just off the top of my head from me as I got up and checked the posts and Blackthorn's therories fit with mine I had more researching to do today on it and havn't done that yet, but I was pretty confirmed in my ideas about the whole thing. And thank you Blackthrone for putting it all so eloqunetly! I will post more later after I have done some checking on a few things.
