Did the Fair Folk somehow overcome or deactivate the Elemental Poles and then pass into the Circle of Earth, the main fortress at the heart of Creation and then were driven back before they could overcome that as well? Were the Poles diminished or did the Scarlet Empress find some way to restore them when she asserted her rule over Creation. Does an elemental dragon have to be at one of the Poles to assure it's stability?
   Where a element is strong it attracts Essence.
    Essence effects each element differently. It follows water to flow in rivers. It spreads from the Pole of Wood and where it spreads forests grow.

   The raging heat of the Pole of Fire is enough to bake Creation dry for a thousand miles in every direction.
   The heat of the Pole of the South and the cold of the Pole of the North are impossible for anyone to survive but are invigorating to the elemental dragons that lived there.
   The contrived nature of the Immaculate Order reflects the approach to writing the game as a whole. Instead of being a mystic order devoted to worshipping the elemental dragons who are the forefathers of the Terrestrial Exalted whose disappearance in a forgotten age has been surrounded by myth, they are deliberately manipulated tools living by the contrived ideology of a third party as is so often the case in Exalted for example the Angry Ghosts. There just aren't any real conspiracies. Perhaps they believe, understandably if incorrectly, unknowing of the Primordials, that it was the Elemental Dragons who created Creation and after their work was complete and they made the Terrestrial Exalted to follow in their footsteps, ascended to Heaven. They pieced together from scattered bits of lore that the Elemental dragons look down on them and select members of their bloodline worthy to be Exalted. After correct conduct during their lives their soul becomes one of the Dragon Blooded and then they finally go to Heaven to join the Elemental Dragons. The world has long since forgotten the Celestial Exalted. The Solar Exaltations imprisoned, the Sidereal Exalted self occulted and the Lunar Exalted driven out of Creation entirely and forced to spend one and half thousand years of exile in the Wyld battling against the Fair Folk as the Primordials once did.
   All that remains are monuments whose purpose has long been lost and tales of the end of the First Age about the hideous cruelty of demons the Elemental Dragons fought against.
   Now everything has been turned upside down. The Sidereals' desperate gambit of removing the Celestial Exalted from Creation forever lest they destroy it and the dragon blooded rule in their stead has failed. The Scarlet Empress has disappeared and the one ruling force across Creation removed the rule of the Terrestrial Exalted seems ready to collapse. The Sidereals themselves having watched Creation from Heaven and only carefully under false identities to direct Wyld Hunts to remove wayward Celestial Exalted are forced to take a more active hand and return to Creation once more. Now that the empire of the dragon blooded is no longer fit to contain them the Lunars can now return to Creation and end their imprisonment outside reality. The Solar Exaltations spill out across Creation remaking heroes the world has not seen for millenia.
   The Sidereals created the Immaculate Order as an ideological bastion to prevent anyone from supporting the Celestial Exalted again. The only remnants of memory of the Celestial Exalted are the Anathema, demonic beings who the Elemental Dragons battled against as they tried to destroy everything the dragons created.
