House Vyronii - Notable House Vyronii Personnel: Grand Master Jahk - The venerable Grand Master Jahk was the ruler of House Vyronii during its reunification with the Imperium and the closing decades of the Great Crusade. He was a figure of controversy within his House, having gained much respect for his clairvoyant leadership and his steadfastness during House Vyronii's long vigil; even staying on their home world of Damaetus to secure his House's future rather than seek glory amongst the stars. Obviously disgusted by the avarice of the divers Mechanicum envoys, Grand Master Jahk proved a consummate politician, postponing the vital question of the House's alignment until its reputation had considerably grown, therefore ensuring House Vyronii's independence. However his obstinacy on the path he had chosen would leave House Vyronii vulnerable at the dawn of the Horus Heresy, the House having still not properly bonded with a Forge World, and thus ensured its resupply when the Warmaster's shadow fell on the Cyclops Cluster. Grand Master Jahk died honourably in what was to be dubbed "The Battle of First Landing" against traitor Mechanicum forces of Cyclothrathe, which had hoped to ambush the assembled Vyronii Knights and wipe them out.Grand Master Gios - Eldest son of Grand Master Jahk, Hero of the Great Crusade and supreme leader of House Vyronii during the Horus Heresy, Grand Master Gios was counted amongst the most lauded rulers of House Vyronii. Through his determination and valiant actions were the Vyronii warned of the impeding attack of the Cyclothrathine Mechanicum on Dameatus III/II which led to "The Battle of First Landing." Following in his father's footsteps, the mortally-wounded Gios would eventually have to be sealed in his artificer-wrought Questoris Knight Magaera, the Dei-phagia, which would keep him alive for many solar years. Determined to avenge his father's demise and exact vengeance on the traitorous Mechanicum of Cyclothrathe, Gios would prove both a competent and brave leader through the dark years of the Horus Heresy.Chancellor Jaastan "the Thrice-Slain" - The scion in command of the venerable Questoris Knight-Paladin Artemisia, Jastaan was a famed figure of House Vyronii. Amongst the most experienced Knights of his House, Jaastan was grievously wounded not one or even two, but three times in the name of the Vyronii and the Emperor. Each time the seasoned warrior would live to take to the battlefield again, until he finally fell on Manachea in defence of Hive Ullan. His wisdom and experience had made him one of the most important members of Grand Master Jahk's Court, and his advice was seldom ignored.Elsbeth Vorr - Elsbeth Vorr is an exceptional figure amongst the Knights of the Vyronii, firstly because she is one of the few women in command of a Knight armour. Her reputation was, however, not solely built on her gender. Elsbeth Vorr is one of the few Knights known to have slain one of the dreaded god-like creatures of Damaetus III/II during the 30th Millennium, slaying the mighty beast on the lance of her Cerastus Knight Lancer Apsinthos after resisting its terrible psionic powers. Her formidable strength of will would continue to serve her well in the years of battle she knew amongst the forces of the Great Crusade. Her promising career ended tragically in a last charge against the Reaver Battle Titan Raxvalian of the Traitor element of the Legio Tempestus, which she destroyed on Manachea. Her ultimate fate is unknown, but it is widely believed that her mortal remains and the carcass of her Knight armour still lie entombed in the rubble of the shattered hive city of Ilium.Caradoc - Caradoc was a House Vyronii Knight that piloted Cerastus Knight-Castigator Meliae during the Horus Heresy. He was among the House Vyronii's Knights, that took part in the Battle for Terra. Disdainful and domineering of his subordinates such as Acastia, during the Battle for the Mercury-Exultant Killzone Caradoc refused to withdraw despite the failing loyalist situation. However in the final stages of the battle before Legio Mortis Warmaster Titans Caradoc panicked and succumbed to a fit of insanity. He attempted to kill Acastia along with her Armiger Knights but was slain by the Legio Solaria Princeps Abhani Lus Mohana and her Titan Bestia Est.Ullus Varrim-Skor - Scion Ullus Varrim-Skor piloted the Questoris Knight Crusader Parisina, which participated in at least three major campaigns of the early-to-mid Horus Heresy before taking part in the Second Battle of Paramar. During the fighting, Parisina was heavily damaged, but Scion Varrim-Skor's broken body was later recovered from the burning wreckage of his heavily damaged Knight. His ultimate fate is unknown.Rothnarl - Scion Acclaimed Rothnarl was the pilot of the Cerastus Knight-Lancer Comitas Zenith during the Battle of Beta-Garmon, the "Titandeath," and he aquitted himself so well that his personal heraldry now hangs in House Vyronii's Hall of Heroes.Elsbet Vorr - Scion Elsbet Vorr piloted the Cerastus Knight-Lancer Apsinthos during the Horus Heresy. She is said to have felled the Traitor Legio Tempestus Reaver Titan Raxvalian. Her own fate remains unknown.Acastia - Bold and courageous, Acastia was a bondsman of House Vyronii and pilot of the Knight Armiger Elatus during the Great Crusade and Horus Heresy. Her role was that of scout amongst a cohort of mighty Titan engines and her fearlessness and endeavour served her well in this regard. She was a warrior born, a free spirit and eager to test her mettle against the war machines of the traitor Legios. Enduring constant abuse by her commanding lord Caradoc, Acastia nonetheless dutifully took part in the Battle for the Mecury-Exultant Killzone during the Siege of Terra, battling alongside the Hunters of the Legio Solaria under Abhani Lus Mohana. However, in the final stages of the battle Caradoc went insane with fear and attempted to slay his allies, but was saved by Abhani and her Titan Bestia Est.Dolloran - Dolloran was a bondsman of House Vyronii and pilot of the Knight Armiger Cyllarus. He took part in the Battle of Terra, the final epic battle of the Horus Heresy. He was slain while defending the Mercury-Exulant Killzone by an undead Titan of the Legio Mortis.Pluton - Pluton was a bondsman of House Vyornii and pilot of the Knight Armiger Thaumas. He took part in the Battle of Terra, the final epic battle of the Horus Heresy.  Tragically, Pluton was slain by his mad commander, Caradoc, when he went insane with fear when confronted by Warmaster Titans of the Legio Mortis.
