Planetary Governor - Notable Planetary Governors: Annesh (Ionis) - Annesh was the planetary governor of the world of Ionis who foolishly led a plan to have his world secede from the Imperium in order to rule his own empire. An Eversor Assassin broke into the Governor's palace in order to kill him, but instead found a bomb and was killed in the resulting explosion. Secretly, Annesh and his co-conspirators observed the explosion from orbit. Gloating at the spoils to come, Annesh was surprised when one of his co-conspirators transformed into their true form -- that of a Callidus Assassin -- who proceeded to deliver the Emperor's judgement upon the terrified former planetary governor.Aulis (Taros) - Former planetary governor of the Desert World of Taros in the Ultima Segmentum, Aulis willingly annexed his world to the expanding T'au Empire, beginning in 978.M41, which culminated in the events of the Taros Campaign in 998.M41. An Avenging Sons Space Marine Chapter Kill-team was dispatched to kill the treasonous former Imperial Commander, but T'au troops saved him and his bodyguard. Following the failed Taros Campaign, the T'au Empire renamed the world "T'ros." Much of the planet's Planetary Defence Force subsequently went on to serve as volunteers in the T'au Empire's military forces as Gue'vesa troops.Gerontius Helmawr (Necromunda) - The governor and ruler of the Hive World of Necromunda in the Segmentum Solar is Lord Gerontius Helmawr. His ancestors are known to have reigned for the past seven thousand standard years at least, and records of government before that time have long since disappeared. The Adeptus Terra leaves Lord Helmawr to govern his domain as he pleases, as it leaves all Imperial Commanders free to administrate their worlds. So long as Helmawr fulfills his feudal obligations to the Imperium his position remains secure.Herman von Strab (Armageddon) - Herman von Strab was the Overlord of the vitally important Hive World of Armageddon during the Second War for Armageddon, during which he gained notoriety for his disastrously inept leadership. He rose to power the same way all others had done before him, through assassination of the other claimants to the Overlord's throne, mainly, his three elder brothers, who considered their younger sibling too stupid, weak and incompetent to take as a serious rival -- to their unfortunate ends. Even before the Second War for Armageddon began, he displayed his ineptitude, and tried to deal with Ghazghkull Mag Uruk Thraka and his WAAAGH!, himself. An even worse military commander than he was a planetary governor, the poorly ordered forces he had at his disposal were quickly overrun and destroyed. When Space Marine forces arrived, Lord Commander Dante of the Blood Angels Chapter took command of the beleaguered planet, and placed von Strab under house arrest. Somehow, von Strab escaped in a stolen Land Speeder, which was later found badly damaged, but his body was missing. His whereabouts remain unknown.Lukas Alexander (Kronus) - Governor-Militant and Astra Militarum General Lukas Alexander was initially sent to the world of Kronus in the Lithesh Sector of the Segmentum Ultima to track down and capture Farseer Taldeer after her actions on Lorn V. His forces landed in an abandoned city, and found traces of ancient relics scattered across the planet, including a Hellstorm Cannon, a piece of weaponry from the Horus Heresy-era Imperator-class Titan Aquila Ignis. The city was renamed "Victory Bay," and Tech-priests began excavating the Titan's massive Hellstorm Cannon. The Imperium then granted Lukas Alexander the title of "Governor-Militant" of Kronus, and tasked him with conquering the planet for the Emperor.Lufgt Huron (Badab Primaris) - Lufgt Huron, the Tyrant of Badab, was once the Chapter Master of the Astral Claws and self-proclaimed Imperial Governor of the world of Badab Primaris in the Maelstrom Zone of the Ultima Segmentum. But ultimately, Huron became corrupt in his ambitious pursuit of power and corrupted most of his Chapter as well, leading him into open rebellion against the Imperium of Man, known as the Badab War, which lasted from 901-912.M41. Bound to machines which keep him alive and forever in pain, Huron is now a scarred creature of hate known as Huron Blackheart, the Chaos Lord of the Renegade warband of Heretic Astartes called the Red Corsairs.Marius Hax (Scintilla) - Marius Hax is the sector lord of the Calixis Sector, an Imperial sector located in the Segmentum Obscurus on the northern edge of the known galaxy, adjacent to the Halo Stars and the Eye of Terror. As sector lord, Marius Hax is the most powerful man in the Calixis Sector, who rules over his vast domain in the name of the Adeptus Terra from the Lucid Palace on the sector capital world of Scintilla.Mykola Shonai (Pavonis) - Mykola Shonai was the planetary ogvernor of the Imperial Mining World of Pavonis, located in the Segmentum Ultima. Following a brief, but bloody civil war years earlier, Mykola was replaced in office by her nephew Koudelkar. Behind his back, his aunt proceeded to invite a T'au trading congregation to the Governor's Palace in the hope of making Pavonis prosperous and independent again. Enraged at her actions, a vicious firefight erupted between the Governor's forces and his aunt's. During the fighting, Koudelkar was kidnapped by the T'au and turned to their cause of the Greater Good. Captain Uriel Ventris of the Ultramarines Chapter later arrived on the scene, and, after killing the remaining T'au, sent Sergeant Learchus on a covert mission to rescue the governor. A full-scale war was fought across the planet between the T'au forces and the Ultramarines' 4th Company. When defeat seemed inevitable, Uriel threatened to destroy Pavonis from orbit and the Tau withdrew. During the war Governor Shonai was killed, but not before repenting and pledging his allegiance to the Emperor once more. After the invasion was repulsed, the Administratum assumed direct control of the planet, and any remnants of autonomous government were completely eliminated.Pella (Donia) - Pella was the planetary governor of the Civilised World of Donia located in the Segmentum Pacificus during the early 41st Millennium. He is notable for being the father of the renowned Astra Militarum commander, Lord Solar Macharius.Duke Severus XIII (Kulth) - Under the leadership of the former Sub-sector Governor of the Periphery, Duke Severus XIII of Kulth, the Severan Dominate is a confederation of worlds located in the Periphery Sub-sector of the Calixis Sector in the Segmentum Obscurus that has seceded from the Imperium of Man, and is currently in open rebellion.Yawell (Morisha) - When a Venenum Temple Assassin, Urhua Theraux, was despatched in 563.M37 to assassinate the Renegade Planetary Governor Yawell of the world of Morisha in the Segmentum Ultima, during transit the Assassin's starship was caught in a Warp rift, holding the vessel in a temporal stasis for some six hundred and ninety-eight standard years. Not knowing that a Warp time dilatation had occurred, Theraux proceeded to her destination, only to find her original target long dead, and replaced by an anti-Imperial democratic committee, consisting of some 1,000 members. Undaunted, Urhua Theraux succeeded in killing the entire committee after spending three whole solar days poisoning all the chairs in the council's auditorium.Vardus Praal (Isstvan III) - Vardus was an Imperial baron and the planetary governor of Isstvan III in the last days of the Great Crusade. He was corrupted into the service of Slaanesh by the Chaos sects already present among the native population of the world and led a rebellion against the rule of the Imperium. Praal was slain when four Space Marine Legions commanded by the Warmaster Horus launched a massive assault upon Isstvan III's capital, the Choral City. Praal and his corps of potent Renegade psykers known as Warsingers were slain during the Imperial offensive. Following the rebellion's defeat, Horus unleashed a Virus Bomb assault upon his own troops, determined to eliminate the Loyalists among his ranks before he began his own rebellion against the Emperor. The population of the world was largely eliminated by this betrayal, remembered to history as the Isstvan III Atrocity.
