Shaping, a not so brief explanation
Shaping is the art, the technique, and the study of the structure by which the laws, concepts, and phenomenon of reality, both physical, metaphysical, non-physical or otherwise exist and work. It is based in the theory that it is the shape of a given reality or universe that determines the structure and function of its laws and other constituents. It is through the study and discernment of the shapes of the laws and phenomenon of reality that one can eventually learn to replicate them.
Shaping is quite a free form methodology for all that it works of the constant of shapes. This is because just as all matter and energy are constantly interacting with each other, so too are the shapes that define those interactions all tied together forming and breaking connections as they define their associated laws or objects. As shapes change objects change and vice versa. As a result of this the actual methodology by which shaping is performed is incredibly variable and diverse. It could be performed through a method akin to the various magics of reality, it could be done through a though process or meditation, it could be accomplished through a skill or technique or bodily movement, it could even be built as a piece of technology. So diverse are the methods of shaping that some shapers may not even know that they are shapers.
This difference between knowingly acting as a shaper and doing so unknowingly brings separates shapers into the categories of Natural Shapers and Knowing Shapers (typically just shapers). An example of a typical natural shaper would for instance be a swordsman who has perfected some part of their stances, form, or movements in accordance with a shape and have potentially further grasp the way of applying their energy to actively manifest the shape. For example a skilled swordsman who's demeanor or mindset allows them to pick what they will cut no matter the force they apply, or more distinctively a swordsman who can give life with a cut of his blade rather than merely taking it (while some of these capabilities are quite possible or even common for non-shapers in the field, shaping effects typically have primacy over non-shaping ones as they exist at the level of natural law or phenomenon at a minimum). On the other hand a knowing shaper knows what it is they have been studying or attempting. As a result of this they often find it more difficult to find a means through which they may actually apply any knowledge of shaping they may acquire but this active knowledge makes what they can do with it much more variable and makes it that much more likely they will be able to progress in the art, scale up their abilities and the effects they can manage, as well as expand their capabilities to shapes distinct from the one they first learned.
Despite the promise of being able to essentially reconfigure the workings of reality with effort and will it is quite difficult to actually learn shapes and even harder to work out a means of actually using them to produce their associated phenomenon. Shaping is a field that has little regard for talent as there are few if any surefire methods to actually learn a shape even with a mentor to walk one through it. Shapes are by there very nature difficult to comprehend and even if one can hold the whole of a shape in their memory, they may very well be missing the most crucial components that make it "alive" so to speak. This is even understating the level of difficulty to even learn the base form of a shape be it through research and experimentation, or through meditation and naval gazing, or other means of study. Shapes are inherently vague slippery things and the variants and relatives of any give shape are without limit.
This difficulty though has done little to discourage people the world over because of the extreme potential of shaping no matter what medium you perceive and perform it through. From simple shaper adepts with exotic effects that are far more powerful than they might initially appear to master shapers who have surpassed the realm of human capabilities and earned the right to trample most gods into the dust, to the utterly incomprehensible grand shapers who can create or destroy entire realities just by the act of existence (though from what few interviews I have been able to find it seems they mostly restrain themselves). The power and capacity offered by shaping is limitless if one has both the diligence and perspective to grasp it.
Shaping begins with the earning of but a single shape, what ever it may be. This is usually tends to be a shape of medium complexity as those are the easiest for those of an unlearned perspective to understand (Nearly all shapes are themselves pieces of other shapes save for the truly elementary shapes which are often difficult to understand for those used to a certain level of complexity without working them out from subdividing an already known shape, which is itself quite difficult. Shapes that cover the whole or a vast expanse of a single subject are equally rare for similar reasons. For more on shapes refer to the sections Shapes, a somewhat comprehensive guide.) The first shape usually has a particularly significant role in a shaper's development as it is the initial lens through which they come to investigate the world.
Initially most shapers, nearly all save natural shapers (who likely do not even realize they are shapers) and those that have a mentor, will be unable to do anything more than sense the shape and expand their perceptions of the world through it. Eventually through practice a shaper will eventually learn to form a sufficiently unaspected energy into the shape by one means or another (the methodology used can be nearly anything so long as it can properly form the shape. After which it is through experimentation and exploration of the capabilities of their shape that a shaper can eventually earn themselves and easier time either expanding upon what they know of the shape towards greater or simpler levels of complexity or learning new shapes altogether. All of these paths of progression are incredibly difficult so every little advantage is incredibly helpful to a new shaper trying to reach mastery.
There are a myriad of potentials even a new shaper can unleash from a given shape. It of course starts with the perception of the world through that shape, and all that is related to the shape through its context allowing one to vastly increase their knowledge of and sense for the associated phenomenon, object, or law of the shape. More active uses of the shape start from the temporary expression of what the shape represents and quickly progresses to the semi-permanent replication of objects, law, or phenomenon in accordance with the shape. As one grows more skilled they may stretch and change the specifics of the shape as they use it doing more than merely replicating something perfectly, to creating their own version of it though it takes quite a lot to actually leave the initial bounds of the shape. Ultimately a new shaper works to progress to the point where they can naturally and quickly string several shapes together with specific details added to each for desired effects producing desired results on short notice, this is the highest capability of a shaper before they achieve mastery for themselves either through awakening or an initiation.
