Legio Invicta - Notable Personnel: Pietor Gearhart  - Pietor Gearhart was the princeps maximus of the Legio Invicta and the commander of the Warlord-class Titan Invictus Antagonistes during the defence of Orestes. Several centuries of skillfully applied warfare, along with his own temperament, had earned him the name "Red Fury". At the time of the Sabbat Worlds Crusade and the defence of Orestes he had already been the Legio's princeps maximus for nearly three Terran centuries, and due to the long exposure to his Titan's mindscape was struggling to maintain his sanity while in the embrace of his Titan's Machine Spirit. At times during the defence of Orestes, he was haunted by hallucinated phantoms of his former crewmen and masters, and was struggling to remember the names of people he knew -- unconsciously substituting for them with those of his apparitions. Despite these drawbacks, he led his Legio to the successful conclusion of the Orestes Campaign. He did not shun risk, trusting that the Red Fury that gave him his name would deliver him as it always had. For this reason, when the Traitor Titans began to converge on the ruins of Hive Argentum during the defence of Orestes, Gearhart, against the advice of some of his senior princeps, decided to battle the enemy force, hoping to wipe it out entirely -- though such a fate might have been that of his own Titan Legio. Gearhart's assertion proved correct, as his forces won the battle. After the fighting had ended, he wished to move the forces of the two Legios back to the forge city to restore order, but was confronted by the Legio Tempestus. Despite being outnumbered by a four-to-one margin, the Legio of Orestes' acting commander issued Gearhart an ultimatum, telling him to stand with the Legio Tempestus or against it. Gearhart's unflinching and unyielding attitude may have very nearly sparked a civil war within the Mechanicus. Bloodletting between the two Legios was only averted by the emergence of a new threat posed by a previously hidden Traitor Titan battlegroup. Gearhart led the two Legios to victory in the final battle of the war on Orestes, and soon afterwards, the danger of a religious schism was over. Immediately following the campaign, Gearhart is shown as still being in command of the Legio. His ultimate fate, and whether he succumbed to his insanity, is unknown.Bohrman - Bohrman was a first princeps of the Legio Invicta during the defence of Orestes and the commander of the Warlord-class Titan Divinitus Monstrum. He was Gearhart's second in command, and was being prepared to take the position of Princeps Maximus when Gearhart finally loses his ability to lead the Legio.Vancent Kung  - Vancent Kung was the princeps of the Warlord-class Titan Sicarian Faero during the defence of Orestes. He was the commander of one of the Titan battlegroups assaulting Hive Argentum, and was tasked by Princeps Maximus Gearhart to destroy the Traitor Imperator-class Titan Augmenautus Rex. Kung linked his MIU (Mind Impulse Unit) with those of Titans from three battlegroups to take down the Traitor Imperator-class Titan with an assault coordinated by a single mind. Such a measure, although forbidden, was required as the Augmenautus Rex 's Void Shields were so potent that they would have withstood a more dispersed assault. Kung had controlled a large number of Titans for only a few moments during which he succeeded in disabling the Chaos Titan, but this effort weakened him considerably.Levin  - Levin was the princeps of the Titan Ajax Excelsus. He commanded a second front of war engines which struck of the Gynex Sub-hive on Orestes to support the attack on Hive Argentum from the south. His forces assisted in bringing down the Traitor Imperator-class Titan, Augmenautus Rex.Stent Racine  - Stent Racine was the princeps of the Reaver-class Titan Philopos Manix during the defence of Orestes.Maximillian Orfuls - Maximillian Orfuls was the princeps of the Warhound-class Titan Morbius Sire during the defence of Orestes. He was noted as being a senior war engine pilot, and is credited with drawing first blood for the Legio Invicta on the surface of Orestes.Leyden Krugmal - Leyden Krugmal was the princeps of the Warhound-class Titan Lupus Lux during the defence of Orestes.Talentine - Talentine was the princeps of Warhound-class Titan Martial Nox during the defence of Orestes. Talentine died during the drive on Hive Argentum as a result of an ambush set up by Traitor Titans.Skaugen - Skaugen was the princeps of the Warlord-class Titan Dominatus Victrix during the Beltran Cluster Campaign. While fighting the graceful Eldar Titans his war engine sustained damage and he himself was severely injured. As a result of this, Skaugen was put in stasis in hopes of preserving his life, however he died shortly after the Legio Invicta arrived on Orestes.Zane Tarses - Zane Tarses was a Moderatus of the Warlord-class Titan Dominatus Victrix during the Beltran Cluster Campaign and the defence of Orestes. After his princeps had died in Orestean facilities, Tarses, blinded by grief and rage at the efforts that seemed to him to be only diminishing his master's faculties, murdered the Magos Organos that tended to Skaugen. While such a crime would normally have seen Tarses executed, the circumstances the Legio Invicta was in led him to be temporarily spared. The Legio faced numerous foes and needed all of its available engines. The Dominatus Victrix would be repaired and a new princeps -- Guido Prinzhorn -- would be provided for the war engine by the Legio Tempestus. Tarses knew the machine, and it knew him. He was required to ease the new princeps into enmeshing with the war engine's Machine Spirit to make sure that the Titan operated at full capacity. To this end, Princeps Maximus Gearhart ordered Tarses' crime overlooked and the charges suspended until the conflict on Orestes was over. Like all Proximus Pattern Warlord-class Titans, the Dominatus Victrix required a full-immersion amniotic interface to operate it, and this Prinzhorn could provide. Despite being a young princeps, and one who had never seen actual combat but only simulations, Prinzhorn was interred in an amniotic tank. Prinzhorn was afraid of his first real command, and was predictably less able than a more experienced Titan officer. Prinzhorn was aided in his charge by Tarses, even though he was initially reluctant to accept this help. Following the battle for Hive Argentum, after the publication of the revelations which allegedly proved the truth of the Orestean Heresy, Legio Invicta Princeps Maximus Pietor Gearhart wished to move the forces of the two Legios back to the forge city to restore order, but was confronted by the Legio Tempestus. Despite being outnumbered by a four-to-one margin, the Titan Legio of Orestes' acting commander issued Gearhart an ultimatum, telling him to stand with the Legio Tempestus or against it. When Legio Tempestus war engines acquired target locks on the Legio Invicta 's Titans, Prinzhorn did the same, but was stopped by Tarses, who forced the princeps to shut down his Titan at gunpoint. Bloodletting between the two Legios was only averted by the emergence of a new threat posed by a previously hidden Traitor Titan battlegroup. Prinzhorn and Tarses proceeded to take part in the final battle of the war on Orestes. Tarses' ultimate fate is unknown.Djared Crusius - Djared Crusius was an Executor Fetial, a diplomat, of the Legio Invicta during the defence of Orestes. He was present on Orestes during his Legio's transit from the Beltran Cluster to the Sabbat Worlds front, and negotiated the aid of the Legio Invicta with the Orestean Magi. During the campaign, he travelled behind the forces of the Legio in a guarded, armoured convoy, supporting them in any way he could -- serving as a liaison between the various units and entities, Imperial and Mechanicus alike, and monitoring the events in the entire theatre, providing all of this information to Princeps Maximus Gearhart.Sonne - Sonne was the Famulous of Executor Fetial Djared Crusius, apprenticed to one day hold this station himself. Sonne was most often found at the side of his master, though he was occasionally sent away on errands. Because of this, he was present, along with a Legio Invicta Skitarii escort, in the forge city of Orestes Principal during the coup d'etat which occurred after the publication of the revelations concerning the Emperor's supposed lack of divinity. Using his master's security codes, he was able to extract a witness of the Adept Seniorus' murder from the forge city and deliver him to Imperial authorities. The account of events delivered by this witness served to further and finally convince Gearhart to move against the forge, as he had all the proof he needed of the Orestean Heretics' duplicity.Lau - Lau was the Master of the Legio Invicta 's attached Skitarii forces during the defence of Orestes. Like all of the Mechanicus' Tech-Guard he was heavily augmented with cybernetic implants which were designed for combat. He commanded his troops personally and was often found fighting on the first line -- despite numerous admonitions from his princeps maximus. Lau claimed that doing so prevented him from ever becoming complacent about the lot of the Skitarii under his command, but Gearhart believed him to be simply addicted to the adrenal high of close combat.Kovenicus - Magos Navis Kovenicus of the Adeptus Mechanicus was the Master of the Legio Invicta fleet, in command of all of the Titan Legion's naval assets. When the reveletations concerning the Emperor's non-divinity were made public by the Orestean Heretics, Kovenicus, in correct anticipation of Gearhart's orders, placed his vessels in geo-synchronous orbit over the forge city of Orestes Principal to make ready for orbital bombardment and the deployment of reserve troops, in preparation for the possible outbreak of a civil war between the forces of the Orestean Mechanicus and those of the Imperium.
