I do remember it having ten elements. It wasn't designed with ten in mind, that's just how many emerged as I was working it all out.
I hope you find it, Jas ... I always find your work interestingly thought out.
Here you go. The earlier elements are similar (but not identical to) the classical elements, so I've written less about them. The later one's I've explained in greater detail.
-- Represents foundation and stability.
-- Water gathers where there is earth.
-- Represents growth and spontaneity. Plants spring up where there is water.
-- Plant respires and creates Air.
-- Where there is air to breathe, animals can survive. This element represents the mind, and consciousness.
-- Animal discovers Fire, and becomes elevated above other animals. Fire represents power and control. Fire is that which the mind seeks. Fire can be either tame or unleashed into something devastating. The mind too can be tame or devastating in how it uses the power it wields.
-- The furnace can smelt Metal, and metal can be made into tools and machinery. As the metal is refined by the smith, the skill of the smith also becomes refined and honed. Metal represents this skillful mastery, art and craft and creativity.
-- Beyond the art of the smith we have the image of the wizard holding his gem encrusted scepter, staring enigmatically into his crystal ball. Crystals and gemstones are rare and unusual things: beautiful, curious, perfect, unworldly even, much like the arcane intellect of the wizard himself. Crystal represents all that is arcane: the science through which advanced materials can be engineered; the processes we can solve and improve by juggling information and running algorithms; or the knowledge and understanding through which we transcend our limitations.
-- With the knowledge and understanding of Crystal, we gain the means to transcend our limitations. We widen our horizons and go forth into new worlds. Chaos represents mobility and expanses, the vastness of the unknown, the frontiers which baffle us, and the mysteries that confuse and torment us. In some ways, we can think of Chaos like separation and distance: the difference between here and there, the difference between present and the future, and the difference between the known and the unknown. As we "advance" ourselves, we endevour to reduce this sense of separation, so making it easier to move from here to there.
-- As we reduce this sense of separation closer and closer to zero, we engage in a nullification process, where aspects of our lives become lost. Null represents the scales of balance, and the equivalency of loss and gain: We solve a mystery, and the mystery loses it's magic. We complete a rewarding challenging task, but sadly don't have it to do anymore. We create faster travel and we lose the experience of the journey, as well as it making the world seem smaller. So for all our efforts, Chaos only gives way to Null. Null is our ultimate nemesis, and also our wisest teacher.
