AN: And another commission, this one a worldbuilding piece
The art of formations is an often frustrating one. Even with the best and most talented of apprentices, the full support of the Empire and all of its wealth, so much is lost with the death of a master. With great care, his works might be maintained for a time, but in no more than a century or two, they will need replaced. Talisman craft is less prone to decay, but even then, only those talismans which acquire a life of their own will last in perpetuity, which brings its own problems.
The source of this decay, most posit is the same as that which prevents true material immortality. The same reason that even seemingly unaging spirits and beasts grow more prone to torpor with age, taking on the qualities of geographic features to stave off their end. Yet, in time even mountains are worn away and rivers wear new courses, ceasing to be themselves. Some scholars have even posited signs that the very earth on which the empire was founded has moved though imperceptibly, since the founding, driven by the eons long migration of the mighty spirits of the earth.
No matter how well the material form of an array is reinforced, it's spiritual element will always be open to change and erosion, just as our own spirits are, no matter how mighty. The universality of decay and the forward flow of time are the two principles which have proven unchanged and unchangeable since the beginning of the world. It is these principles which render so much of our gains in the arts of formation building to be ephemeral. So it is with formations arrays. Without it's maker to reinforce and adjust it, the constantly changing state of the world will reduce even the most finely preserved arrays effectiveness, until at last it ceases to work altogether.
Even the simplest formation, within the abilities of the meanest novice to craft has a spiritual shadow, an imprint in the spiritual realm carved and filled by the creators qi. What then, does this mean for the work of masters? A Master of formation craft naturally designs his works with an echo of his own spirit and Way imprinted upon them, entwined in their every function. Indeed, ones way is deeply important to the sort of masterworks which one wishes to create. While lesser items might be crafted with minimal use of the Masters domain, any array crafted at the limits of a masters ability will involve painstaking use of ones domain to shape and design the array and achieve its aims.
Thusly, powerful formations are indelibly the work of their makers, their effects might be copied or reproduced, but each array or talisman is a unique work, imprinted to it's foundation with it's makers qi. A True Master of the craft might be able to make designs which are 'neutral' able to be copied or emulated by his lessers and peers, but this is an exhaustive and often distressing process and produces effects so much less potent that many masters do not bother.
Those who do make such achievements, who advance knowledge of the craft such that any might benefit from it, rather than only kith and clan, we honor with the name Grandmaster. However, many, many effects simply lie beyond the abilities of any who do not have not formed their second dantian and refined their qi into shen. Qi alone is not enough to imprint coherently the intricate webs of energy which power and instruct the effects of the greatest of arrays. Of those masters who achieve the highest realms and attain Sovereignty, I will not even speak. Their works are beyond any price, and utterly irreplaceable. This humble scholar would not dare to intimate that he has knowledge of such things.
Instead, we will speak of those crafts folk who form the backbone of the Empire, third and fourth realms whose works maintain our walls, craft our tools, build our ships and enable communications and government across the empire. A Formation master of this quality is an important asset for any city or settlement and acquiring the use of one is among some circles what marks the transition between a mere town or village and a burgeoning city, and the loss of such expertise, the sign of decay. This scholar will not weigh in on such civic matters, but there is perhaps a seed of objective truth in this. Walls and wards designed by such a craftsmen will not simply deter spirits, but will totally bar their presence unless broken. A city with a barrier designed by such a master can withstand sustained assault, even from a cultivator of higher realm, at least for a time. Under their eyes, fields and mines can be more productive, streets more resistant to disease, or communications instantaneous. Of course, the efforts which any given master can put forth are informed by his specialities. It is a rare master indeed who can perform all of these things.
Any master of this skill level will swiftly find themselves accumulating apprentices and assistants, though the form this takes varies from region to region. The Bai and Zheng are both rather infamous for keeping such matters 'in house' as it were. The Xuan Clan, those fabled masters of sea and ship, practice similar secrecy, though they are known to adopt the occasional outsider of superlative skill, with the most esteemed example being the esteemed Grandmaster Wu. Many young craftsmen and women in the north look with starry eyes upon such a dream, which causes consternation in some corners. The Guo are similarly generous, but their environs render their offers rather less desirable.
It is the role of the apprentice to carry the masters work into the future. They cannot preserve a masters arrays together, but one who has studied well under their master will be well placed to replace, maintain, and perhaps even improve upon their masters works for future generations. It is thus a terrible blow to any city for a master to die without a fully trained apprentice, for it places them upon a strict time limit, after which much vital infrastructure will cease to function.
Indeed, it is the humble craftsman or woman who allows the warriors of the empire to fight, knowing that their homes lie secure and well tended at their back. As vital as any master swordsman or general, the master craftsman is an honorable role which brings wealth and security both to others and the craftsman themselves.
This is why it is so often frustrating to see our works and personages denigrated, treated as if we are less important than those who go out to shed blood. Young craftsmen, never allow yourselves to be taken in by this vainglorious lie, and know that your work is most vital indeed.
And in remembering this, recall the bonds with your comrades and teachers, and do not allow yourself to be pitted against one another by your patrons. We are siblings in knowledge and siblings in toil…
