A name that spanned the eons
There has been a Saz Vok'Chi within the clan for generations, as old as the clan has been there has always been a member of the family who was dedicated to the creation of armour and helmets.
So much so, Vok'Chi family historians have worked back through the generations of family tellings, historical documents and folklore to discover that the meaning of Saz (a rather perculiar and unique name within mandalorian diction) was infact the marrying of the words Cyare buy'ce (Shah Ray Boo chay) shortened to Cya'ce (Shah Chay) and eventually being softened to Saz. Many phonetic historians believed that Saz became a pet name based from "Shach".
Several documents reveal that the first recorded Cya'ce Vok'Chi was a Taung who stared into the very soul of the ancient dragon that lived in "the dusty sun" (believed to be Tattooine). Cya'ce Vok'ce (Vok'ce was the Taung spelling of Vok'Chi) stole the soul of the dragon and his lineage passed on this soul from father to son.
At some point the Taung lineage moved over to human, as there were few documents pertaining to actual Taung Cya'ce, however, it was clear that, to prove their lineage was just as strong, a ritual developed for the young ones to take on the name of Shach if they were able to defeat a Krayt dragon on the desert world of Tattooine.
It was believed that Shach was a title of honour in the Vok'Chi clan, to be a helmet maker, one must steal the soul of the dragon and be renamed Shach, many Vok'Chi tried for this honour, but died in the attempt. To succeed would mean that the honour of having a Krayt tooth or claw at one's belt would signify a Shach Vok'Chi, some also wore a facial tattoo over the left eye of a Krayt crawling across the skin to signify their name when not in armour.
In some rare documents found of one early Mandalore, it was said that Shach only pass on their skills to another Shach, they are adopted as sons, brought into a secret clan of only the best helmet makers.
It was also said in one folklore that a Mandalore "killed the Shach" so his armour would remain unique.
It may have been this event that led to the adoption of Saz as a name, as some historians contraversially theorise that the Mandalore didn't kill the maker of his armour, but prevented anyone being named Shach, so that his armour would have more distinction to the individual. As the last mention of Shach historically, this could well be the case, we will never be sure.
We do know after that period the first documented use of the name Saz was around 4000 BBY, around the time of Mandalore the Indomitable, though the Vok'Chi followed the ways of the Neo crusader, the honed skills of armour making were being moved away through repetition and the need to churn out armour, left no room for the love of creation, Saz Vok'Chi was believed to have criticised Mandalore the Indomitable for his lack of care when it came to the Neo Crusader armour designs. This earned Saz Vok'Chi a place on the front lines, where he was killed in combat.
There was also a Saz Vok'Chi around the time of the Mandalorian Wars, this Saz Vok'Chi worked with Canderous Ordo (Mandalore the Preserver) to help rebuild the Mandalorian culture from the ground up.
A Saz Vok'Chi was also mentioned during Mandalore the Uniter's reign in 1051 BBY onwards, it was during this point that the traditional Tattoo was made into a distinctive helmet for warriors who had proven themselves against the Krayt Dragon, only 20 warriors managed this feat and the 20 helmets made during this period were passed down through clan families as heirlooms.
The distinct dragon helmet became the mark of Saz Vok'Chi, it was his mark as a maker of armour and a holder of the Krayt Dragon's soul.
As for the request for knowledge as to whether a Saz Vok'Chi exists today? I believe it to be the case, last known Saz Vok'Chi was killed with his wife during a Death watch Massacre in and around 60 BBY, but his son was found to be missing. Now, I know that skills are taught early in Mandalorian culture, so there is a good chance that, should this son have survived, he will have the knowledge and will probably take up the mantle of Saz. That is of course if he hasn't been killed in an attempt to steal a Krayt Dragon's soul.
Unproven claims made around the Saz Vok'Chi name
To ensure I have a fully covered your request Senator Palpatine, I thought it prudent for you to look at these unprovable snippets of information gleaned from my research into the Saz Vok'Chi armour making lineage.
1. It is said that a Krayt Dragon will "always bow to a Shach" prior to combat to acknowledge that they own a dragon's soul.
2. It is rumoured that a Shach was involved in the making of the original Mandalore mask, or perhaps made custom helmets for important Mandalorian members in society, of which the Mandalore was always one.
3. We know that the Vok'Chi clan wholly refutes a claim that a Saz Vok'Chi made the distinctive Deathwatch helmet and that the Saz Vok'Chi was murdered to prevent him from revealing any secrets or flaws from the helmet. Indeed, it would have been more likely that the Mandalorian known as Jango Fett would have been involved in the killing, had the Saz Vok'Chi of that period been involved.
4. The Saz Vok'Chi lineage are the only ones who know how to "bend" Beskar, I think this is claiming that a Taung Shach was the first to work out how to fold the unique metal into armour that even a Jedi's lightsaber couldn't penetrate.
The true tradition of Shach (Saz)
Passed down throught the Vok'Chi clan is the rite of Shach, it is a tome written by the old Taung elders of the Vok'Chi clan and is passed from clan leader to clan leader. It tells of the voluntary rite of passage that every Vok'Chi armour smith might go through to prove that they are also a warrior.
To be the one named Shach you must go to the co-ordinates provided and make a pilgrimmage unto the desert, there you will encounter many of the dangers, should it be scaled, tall and horned, you will have found your prey. Kill it and drink of its blood, the dragon will render its soul unto you. - Excerpt from the Vok'Chi Elder Tome.
Should a Vok'Chi armour maker prove himself in combat by killing and drinking the blood of a Krayt dragon (As well as bringing back the creatures tongue as a gift to the clan leader), then that armour maker would have the right to name himself Shach, later to be changed to Saz.
There may be only one Saz per generation and the son of a Saz may not necessarily survive the ritual, which meant that the Saz of their time tended to have many children (including adoptions) in hopes that their skills be passed on and continued.
Any child that had the gift of building armour were seconded to be trained by the Saz Vok'Chi of their generation. Many who did not take up the name, still had great careers as Mandalorian builders, though only the name Saz was synonymous with armour maker and a warrior.
Saz Vok'Chi vs Mandalore the Indomitable
Though it was documented in history that Saz Vok'Chi was sent to his death by Mandalore the Indomitable, the truth was actually nearer the bizarre.
It was true that Saz Vok'Chi of the time was not keen on the armour, citing several flaws and was desperate to advise Mandalore the Indomitable on the potential weaknesses. The Saz Vok'Chi had already fathered 15 sons and felt that only a true demonstration of the weaknesses could become clear if the Mandalore could see them for himself.
Saz Vok'Chi sneaked onto the front lines and communicated his intent to the Mandalore, who watched Saz Vok'Chi singlehandedly fight off 4 Jedi, right up until what seemed to be an innocuous blow felled the warrior.
Indomitable looked through the pre written message to show the Mandalore where the weaknesses were in the armour, indeed in the exact spot where Saz Vok'Chi was cut down was where he warned Mandalorians could fall foul to the Jedi.
Designs were updated to account for the weakness and Saz Vok'chi was honoured in a warriors poem:
Saz Vok'Chi helps Canderous Ordo
When Mandalore the Preserver came to unite the clans, the Saz Vok'Chi of the time was in full support, the Vok'Chi clan had fractured and was lost amongst the members of the galaxy.
Fully intent on bringing back the clan to a central location, Saz became increasingly vexed by Canderous' insistence on renaming the current members Clan Ordo.
It is when the famous Saz Vok'Chi phrase "I am a Vok'Chi and that's all you need to know!" came about, it was when Canderous questioned Saz's resistance to becoming a member of clan Ordo.
Once it was clear that Canderous and Saz were at odds, Saz left the group to search for his clan members in a hope to return them back to glory.
Rise of the Krayt Buy'ce
It was this Saz Vok'Chi who really cemented the name into the annals of Mandalorian folklore. Many had known the tradition of the shach and chose to honour this tradition within their own clans, though never taking the name, the Saz Vok'Chi of the time offered to build a helmet to all members who took the soul of a Krayt, one that took allegiance to the ancient facial tattoo of the Saz lineage.
In all of Saz's lifetime, only 20 managed to return with red lips and a Krayt tongue, true to his word they received the helmet as a mark within their family. Some still exist even after the battle of Yavin.
Saz's own personal Krayt helmet was unique in the fact that it managed to mix different quality and shades of beskar to have a bronzed Krayt on a silvered beskar helmet. This helmet was passed down as a rite of passage to each successive Saz Vok'Chi, it was the only one made with multiple techniques of beskar and has stood the test of time.
Killed by the Deathwatch
Clan Vok'Chi were amongst the many Mandalorian who refused to rid themselves of the warrior way, banished to Concordia, the clan began to break apart and the Saz Vok'Chi of this time eventually moved away from Mandalorian space, drifting away from his Mandalorian heritage and settling down on a colony world within the Outer Rim.
After several generations of Saz Vok'Chi's, in around 63 BBY the Saz Vok'Chi of that time was approached with making the design for a new helmet, this would be for a superior race of Mandalorians known as the Death Watch. Saz Vok'chi did some digging and found that the Death Watch opposed the way of the Supercommando and promptly refused.
In and around 22BBY the Death Watch returned to Saz Vok'chi's home planet and, as revenge for an insult 40 years in the making, wiped out the whole colony. Saz's youngest son Vencuyot Vok'Chi was away fishing with his young friends, they had the sense to stay away from the fighting, but Vencuyot was orphaned and alone.
Waiting for the Death Watch to leave, Vencuyot gathered his father's remaning possessions, his old armour, helmet and diary instructions for his sons, should he be killed. The young Mandalorian left the protection of the colony to seek out the members of the Vok'Chi clan to pronounce his intention to become the next Saz and have some vengeance.
A Son's revenge
The Mandalorian known originally as Vencuyot Vok'Chi grew up in a loving family, Vencuyot was very young when he was first taught how to hammer beskar. His father had told him about the Rite of Shach and how he too would become the warrior armoursmith known as Saz.
2 days before his 10th birthday Vencuyot and his friends witnessed the decimation of their colony by the Mandalorian splinter group known as the Death Watch.
Vencuyot had been prepared from a young age by his father to deal with losing his family and honing his skills not only as a blacksmith, but as a warrior too.
When Vencuyot was 15, following the instructions from his father's diary, he made his way to Tattooine and, using cunning, guile and a lot of cover managed to take down a Krayt dragon in combat. Once Vencuyot drank the dragon's soul he knew he would no longer be Vencuyot by Saz Vok'chi.
Saz Vok'Chi donned the dragon helmet and somehow sensing the Krayt Dragon's blood on his lips, the database opened up and all the secrets of the generations of Saz were opened up to him within the helmet's Heads up display.
The young Saz presented the Krayt dragon tongue to the Vok'Chi clan leader and offered his services and loyalty as long as he was able to find out who killed his parents and for him to take vengeance.
Much of the Clone wars campaign was dotted with sitings of a Mandalorian with a dragon on the helmet taking out members of the Death Watch as each member involved in the massacre was killed at the hand of Saz Vok'Chi.
A senator's interest
Long before the events of the Clone wars, under the disguise of a Naboo Senator, Darth Sidious began researching into his master plan to destroy the Jedi and bring in a Galactic take over by the Sith.
It wasn't long before the properties of Beskar and the people who could manipulate the aloys and turn the metal into pieces that could deflect even lightsabers came to Palpatine's attentions.
It took a while for his spys to locate Saz Vok'Chi, but little did he know that Death Watch would wipe out his entire family before he could bring the Mandalorian in to "advise" the Republic on how to make the metal so indestructable.
As his machinations carried on, the suspicion that a son may have risen came clear as members of the Mandalorian Death Watch were ending up dead across the galaxy.
Keen to gain the knowledge, Palpatine had his officers lay a trap for Saz Vok'Chi where he accidentally (and unknowingly) killed Republic citizens. Becoming a hunted man, it wasn't long before a group of Jedi and a whole legion of Clone troopers surrounded him. Undaunted, Saz Vok'Chi surrendered to the Jedi, not knowing that the charges would get trumped up and he would be held by the Republic for most of the war.
However, before he was captured, Saz Vok'Chi passed on information through to the Bothan Spy network which implicated that Chancellor Palpatine was deeper into the Clone Wars than was first thought. Wrongly suspecting that this was an attempt to keep him silent, Saz Vok'Chi became a violent prisoner, being subjected to beatings and tortures behind the scenes whilst Republic interrogators and Jedi were unaware.
However, somehow a message came to him that his clan had discovered his whereabouts and were attempting a rescue, during some of his final interrogation tapes he revealed that he was going to be rescued, he knew where his armour was and, on the last interview tape, it could be heard that his fellow Mandalorian clan mates performed a daring rescue.
Once the Empire was declared, Saz Vok'Chi was all but forgotten in the red tape, spending the rest of his time as a Mercenary and a Bounty hunter being one of the few to take great pleasure in hunting down the Jedi, as he wrongly thought that the Force users were the ones who requested his torture.
Saz Vok'Chi lived through the Empire period pretty much unscathed, he kept away from allegiances, only money, though the Empire paid greatly, sometimes his dragon helmet was spotted working for the Rebellion.
Though living the quiet life after the destruction of the second Death Star in 4ABY Saz Vok'Chi continued his armour making.
When the Yuuzhan Vong eventually bombarded Mandalore, though not a protector, Saz Vok'Chi rose to the call in the counter attack, where he died fighting hand to hand with a Vong commander.
Saz Vok'Chi's helmet was returned to his wife by the Vok'Chi clan leader, ready to pass to one of his sons should they choose to take the rite of Shach.
However, the majority of the Saz Vok'Chi's that have lived through the ages have been dark haired. Adoptions have brought in a couple of blond and even a red headed Saz Vok'Chi.
The Early Saz Vok'Chi's have worn a facial tattoo that represents a Krayt dragon in several forms, but the quality of the tattoo has always been in the hands of the artist.
The last incarnation of Saz Vok'Chi was dark haired and blue eyed, with a beard and was deceptively agile whilst looking overweight (especially in his later years).
With every generation gave Saz Vok'chi a new personality, however, each of them shared a quiet "get it done" attitude.
Equipment and weapons
Under the guidance of Mandalore the Uniter, Saz Vok'Chi created the distinctive 2 coloured Krayt helmet that was worn by every Saz Vok'Chi after that.
He also created the unique patterned beskar'gam that is uniquely salvaged by all family members if the Saz Vok'Chi is killed in battle. It is one of the traditions of Mandalorians broken by another tradition of a skill, helmet and armour that is passed down via rite of passage.
Most Saz Vok'Chi's have added their own weapons and gadgets to the armour though, with some incarnations sporting mini guns, rockets and even jetpacks.
Later Saz Vok'Chi's have taken to using the Verpine Shatter rifle as a weapon.
Behind the scenes
In real life the Saz Krayt Dragon bucket is unique in that it has 2 types of cold cast metal to represent the dragon and the bucket. It was the only one created with the method.
