Heizo Renai

Heizo Renai, also known as the Master of Kostillan or Shogun during his time spent in the great crusade was one of the 20 Genetically-Engineered Primarchs created by the Emperor of Mankind to lead the armies of the Imperium during the great crusade. Tragically, Heizo was deceived into waging civil war upon his own father's Empire, a Civil War that Ultimately cost him his life.

Early Life
Hailing from the feudal world of kostillan, Heizo was discovered as an infant and raised in the squalor and poverty of one of the many kostillian feudal fortresses.

As the primarch grew to full adulthood within several years, he spent his early life serving as a warrior in the service of a feudal lord. As Heizo advanced through the ranks and gained more and more leadership he became more and more aware of the hardship the lords exposed to the impoverished of their subjects, many of whom were the families of the soldiers that he served alongside.

During a famine, Heizo was ordered to raze a province his lord controlled to quell the riots of starving people. Heizo refused and staged a military coup, removing the province's lords from power and imprisoning them for their humanitarian crimes.

After the rebellion, Heizo distributed the wealth amongst the people. Improvements to irrigation and infrastructure were made, the people were given educations and given jobs that not only gave them purpose but also worked to improve the conditions of others. Upon learning that the rest of the world suffered as his people had, the primarch vowed to march for their freedom also, raising and training an army specifically for the purpose of liberation.

Over the next decade, Heizo proved himself a skilled warrior and diplomat, often attempting to appeal to the soldiers of opposing armies to fight for what was right, causing them to either surrender or defect to his cause.

Heizo spent a lot of time amongst his men, telling stories and tales of his childhood, tales of war and his exploits. The men loved their leader and would follow him into oblivion, to them the cause Heizo believed in was worth fighting for. The Armies of Heizo were well disciplined, the cities they captured were treated as though they had been reclaimed from enemy hands.

Heizo trained his Generals and officers in advanced battle tactics, ensuring that they were entirely capable of leading forces independantly of him. He was also responsible for the development and use of the Venn style of sword combat, a decisive and clean form of fighting that focused on quickly immobilising opponents. The warriors of his armies utilised his form to devastating effect when assaulting non compliant strongholds, though killing was often unavoidable, it was a last resort. By the time the great crusade reached Kostillan, Heizo had succeeded in uniting the planet under a single banner and was in the process of completely eradicating poverty. Impressed, The Emperor approached the stronghold of his son along with malcador the sigillite disguised as a cloaked advisors.

Heizo granted the advisors an audience and swiftly impressed the two with his humble desire to hear what they had to say despite his clear position of power, even in an age of prosperity, Heizo wished to improve his civilisation even further. It was at this point The Emperor revealed himself to Heizo and offered his son a place at the head of the great crusade, for the betterment of the human race. Heizo journeyed into Kostillan's orbit and aboard the Unification to personally meet  the 10,000 astartes of the Dawn Titans Space marine legion. Heizo insisted the warriors of Kostillan as well as his gene sons choose a name that they wished to carry. Upon pledging their service to their primarch, the sons of Terra and Kostillan had united under the banner of the Honorbound space marine legion.

Crusade
Heizo was not alone in his leadership of the legion, his two most trusted generals from the his days on Kostillan joined him at the head of his legion, commanding his warriors and reshaping the legion into a force of noble and disciplined instruments of war. Haganè Shinro and Yabura Gankai joined the primarch and assisted their lord in the distribution of the kostillian ways amongst the mechanised infantry of the Newly anointed Honorbound.

It was difficult for Heizo and his soldiers to grasp the requirements they had been instructed by the Emperor, but following his first xenos engagement with the horrific Yhaganix, a race of vampiric spiderlike monsters, Heizo accepted that for the human race to flourish sacrifice would need to be made.

A decade later, Heizo had begun leading his legion and in turn commanding the 19 others in the great crusade. It was at this time that the second child of The Emperor would be found, Aes Ferranus, the 14th. Heizo insisted that the 14th legion return to Terra to meet with their gene-father. When the two met, they connected instantly and when Ferran left Terra for the crusade, Heizo journeyed at his side. It would not be until the following year that the Honorbound and Brass Mechanists would part ways until the discovery of Lady Celestia in 811.M30.

As the Great Crusade continued, Heizo was able to forge strong bonds with his siblings as they continued to be found and returned to Terra. While on good terms with nearly all of his siblings, Heizo was particularly fond of his 'Little Sister' Belia Dolvenus and was often one of the first to come to her aid in the Council of Terra when the methods and general secretive nature of her legion came under scrutiny.

Though Celestia and Enkonan had greater talent for statecraft than himself, Heizo often found himself assuming the role of diplomat if discussions became heated. Though sometimes displaying displeasure in some of the choices his fellow primarchs made, it was often as he simply wished for each legion to achieve the best possible outcome in their service to the Imperium. Heizo's loyalty to the Imperium was perceived by some amongst his brethren to be blind. To the Dvergyr, Heizo was simply a carbon copy of The Emperor given form as a primarch due to his habit of taking their father's side in nearly every dispute. However despite this well known dislike, Heizo remained receptive and hopeful for the kinship of each primarch.

While maintaining a strong bond with his 2 former generals, Hagane Shinra and Yabura Gankai and entrusting them with their own clans to command as they saw fit. Heizo also recognised the importance of preserving what had made his legion unique during the early days of the crusade, to do this he took the former legion master Nazai and granted him his own great clan to command under the name of Orekai, instructing the former master to lead as he saw fit. The former commander of the legion's covert operations turned battlefield commander Hidan was also granted his own Great Clan, the Sakea. The great clans were created to incorporate both Terran and Kostillian recruits into their ranks in the hopes that a balance between the two cultures could be established.
