One of the things that I expect the kolduns of Swashbucklers of the 7 Skies to do is to attempt to explain how the various gifts interact in an attempt to gain a greater understanding of how stuff works. One of the things I expect that they would do is try to work out how each of the gifts are connected. The following is my second attempt to imagine how a koldun might perceive the interrelationships (the first attempt was a previous version of this entry; in writing it, I discovered further correspondances).
The diagram to the right is the "elemental wheel" of gifts. I'm fairly sure of the base of this wheel, since it emulates the structure of the skies, with the appropriate gift given a central place in each sky. The top part is more supposition. Placing Water/Kappa in the Sky of Mists seems the best fit, given the life-giving properties of water. I felt there was a strong connection between Rock/Kobold and Metal/Cyclops which tends to indicate that they are adjacent. Since this places Metal in the Ghost Sky one could increase the philosophical connection with metal creating ghosts (in the form of weapons). Or metal being the ghost of a rock. Which leads to metal weapons having a spirit of their own. Placing Darkness/Shade in the Sky of Frost pulls in the paler nature of a winter day and the associations with darkness and cold. Besides equating shade and ghost is a linguistic trick of dubious provenance.
The left hand diagram is based on the relationship of the lesser gifts with the hidden gifts, which I shall refer to as the "mystical wheel." A six-fold symmetry was suggested to allow it to emulate the elemental wheel. Beside it allowed Illusion/Faerie to be placed between Shapeshifting/Chimera and Control/Manticore, which I believe is it's proper place. The remaining minor gifts were then associated with the hidden gifts (the pink lines tend to indicate what I feel to be associations). The whole mess was then untangled to provide a 2D-symmetry (since there is a natural tendency for humans to look for symmetry in deep structure).
One wheel lies atop the other, or rather, you could consider the elemental wheel to permeate the mystical.
Anyway, there is no attempt to be canonical with this. It's simply what a koldun natural philosopher (aka physicist) might consider to be the relationship between the various gifts, in situ. Another philosopher might come up with a different arrangement (say, hinging on a 7-fold symmetry). [The Church would probably declare any attempt to categorise the Gifts of Vaoz as heresy (or at least a serious heterodoxy). The Dome isn't at the stage of turning to the Cosmic Watchmaker as yet.]
Although, that being said, at the next conference of my fraternity I attend, where I shall be presenting this paper, I am declaring the missing hidden gift to be called "PERYTON" and shall endeavour to search for it. That should spark some interesting debate amongst my learned peers. <grin>
Addendum: Certain philosphers have postulated that there should also be a central axial gift on the mystical wheel to emulate that of the elemental wheel, and have taken to calling this hypothetical gift "PHOENIX," representing some dubious form of enlightenment. Personally I don't hold with this belief, as there is no evidence for such a state beyond the wish-fulfillment of those who hold to this dubious philosophy.
