Voids Embrace

Voids Embrace is a form of linkalchemy medical operation presumed to be developed by Void Masters(Actually developed by Stellarch using knowledge from Royal Proteans). It turns half-bloods into void walkers(or Air dancers). It is inspired by firedancer methods and some methods of royal proteans.
Naisha was the only country where the Voids embrace could be performed. It wasn't only a medical operation but also was a training to ready ones mind and body to survive to various operations. The exact method remains secret to almost all except First chancelor of Na'thai Itha, shadow king, pillar emperor of Xean, some insalchemists from Avgannah and some other people...
Once the voids embrace is completed the resulting person(kinda) became known as Air Dancer or Void Walker... They'd be bonded to void masters mentaly, their freedom of mind would be restricted, they would speak soo little, remove their bonds with people(In order to be objective), would be feared and respected by public.
Also, once they were risen, world governments agreed to take care of Air Dancers. A global rule was enacted by almost every country(Except in Xean which refused to sign because of the lack of need, in Afrika because of Money wars and in Yahnst because they're insane) to take care of any Void Walker they encountered.
There is a friendly rivalry between void walkers and firedancers. They sometimes compete on various contests and festivals.
Void walkers known to have sex with people, but it ends up being very mechanical rather than emotional.

Utility

It was used to create Void walkers. It's needs were born out of the sheer size of Naisha; The operation met the countries need for scouts and messengers who could scale very long distances in a short while. Void walkers also functioned as riot police, detectives and sometimes soldiers.

Manufacturing

Requires mastery in wardalchemy to produce the runes. Mastery in Linkalchemy to suceed in operations. Mastery in versalchemy to stabilize the patients and monitor the results.

Access & Availability

Voids Embrace is performed in an unknown place, hidden to almost all people and organizations in the world. Yet it's very widely availible. Anyone who kneels in front of a void master might be choosen to become a void walker. The runes are relatively easy to make(Except the prosthetic legs), most of them are easy to imbue, but the operation itself proves to be very hard and dangerous.
The reason for its localization is, for most alchemists in the world it is impossible to suceed in a such operation. It takes years to complete the whole process. Alchemists believed that patients would die from pain shock over and over again through this process.

Complexity

Runes of Perception: These runes, improves ones sight, hearing and smell. They are easy to produce but very complicated to imbue. It's order to imbue changes depending on the patient and if done wrong, could damage the patient in a unexpected way. Runes of perception also enhances the sensitivity to some sounds and sights, link their perceptions to a specific location and allow them to see this said locations whenever they desire, no matter wher they are; Like they could see a schedule standing inside of a building with thick walls.
Runes Of Manipulation: Hard to produce, easy to imbue. They enhance manipulation and reaction of patients to specific objects or materials. They have to be built custom to it's recipient.
Runes Of Control: Easy to produce, hard and dangerous to imbue. These runes provide one to have more control on their own body and physiology. For example, they can slow their hunger rate, alter their body mass' distribution...
Boonaz Ia Plarchan Garkh: This is the most complex and least known parts of the void walkers. They are extremely hard to produce(Its built specific to its recipient) and even harder to imbue. They improve the recipients walking speed and allow them to glide in air. They were practically indestructible and could be replaced if torn off. They'd act like boots one could never take of. Failiure in it's imbuement could result in death, permanent injury or unexpected, unrelated consiquences.

Discovery

The first form of Voids embrace was developed by Royal proteans. Yet their weaker bodies made it impossible for them to survive the operation. But Stellarch, who had access to stream, adapted the technique and mixed it with firedancer operationts for simpler and safer methods; Which Stellarch implanted on the minds of some pillars. This additions of knowledge, change these pillars more than anticipated and made them void masters; Fighters, surgeons and teachers who was half pillar and half person.
