Navis Nobilite - Major Houses: House Achelieux - This dynasty was a powerful Navigator House during the Great Crusade and the Horus Heresy. The house was tasked by the Emperor during the Great Crusade with researching the mysterious Dark Glass artefact.House Aleene (Nomadic House) - This Navigator house now enjoys the favour that was once the preserve of Lord Angevin's inner circle of Navigators within the Calixis Sector. House Aleene has profited greatly from the upheavals beyond the Periphery Sub-sector.House Balevolio (Magisterial House) - The scions of this house have long been considered the premier Navigators of the Segmentum Pacificus. They maintain a sizeable estate on Terra itself. The Balevolio sailed the stars of what would one day be the Macharian Sector ten thousand standard years before Macharius was born, and directed his flagship throughout his crusade. In the 41st Millennium, they deign to navigate only the most powerful and important vessels.House Belisarius (Magisterial House) - This is one of the oldest and most respected houses of the Navis Nobilite. House Belisarius maintains an ancient and close relationship with the Space Wolves Chapter of Space Marines and exclusively provides Navigators for the Space Wolves' Chapter fleet. In return, the Space Wolves gift the house with a small contingent of Space Wolves Astartes called the Wolfblade who serve as the house Celestarch's (Novator) bodyguard and his strong right arm when the house's interests need to be defended by military force.House Benetek (Magisterial House) - This Navigator house now enjoys the favour that was once the preserve of Lord Angevin's inner circle of Navigators within the Calixis Sector. House Benetek has ascended to great wealth recently and it was "Mad" Abenicus of that house who first postulated a route through the Warp Storms the Calixis Sector into the Koronus Expanse, having made an exhaustive study of ancient texts as well as being wracked by a series of prophetic visions.House Brabazon (Nomadic House) - House Brabazon is a far-ranging Navigator bloodline that chooses not to abide in one single location. Its scions guide vessels the length and breadth of the Imperium, seemingly gripped by a wanderlust that keeps them from establishing the sort of permanent holding most other houses maintain. At one time, the Navigators of House Brabazon were counted amongst the most able in the entire Segmentum Obscurus, their star charts the most accurate, but in one fell swoop, something happened that caused the house's charts, no matter where or how they were stored, to become corrupted according to some grand and unreadable pattern. Unable to trust the firmly established Warp routes of their once jealously guarded charts, they instead seek to forge new ones and pray the curse upon their house does not lay them low once more.House Brobantis (Magisterial House) - An ancient Navigator House based in Vorlese, House Brobantis was known for its considerable resources and many mercantile and political interests and connections. It is an influential house that holds much sway in Vorlese's courts and amongst other major Navigator Houses, although it suffered some losses from political schemes and threats from chaos cultists. Its current Novator, Lady Chettamandey, saved Vorlese from certain destruction by interfering in a heretical ritual which would have plunged the entire planet into the Warp. The house has gained even more power and prestige since its leader was hailed as the Hero of Vorlese.House Cassini (Nomadic House) - A Navigator House as ancient as the Imperium itself, House Cassini was at one time a rising star within the houses in and around the Calixis Sector. But the events of the Chorda Succession laid House Cassini low, providing a salutary lesson in the dangers of becoming too embroiled in the dealings of those who acknowledge no limits to their ambition. Now their fortunes are much reduced, and its scions have been forced to take to the Koronus Expanse in an effort to claw back something of their former glory.House Dakkar (Renegade House) - The name of this Navigator House is a byword for hubris. House Dakkar came into conflict with the Paternova, most prominently during its notorious trade war with House Malaspina during the Angevin Crusade. What had begun as a quarrel over shipping rights into the newly conquered Calixis Sector soon escalated into outright assassination and sabotage. Without the intervention of Saint Drusus, the war might have plunged the entire region into an age of renewed bloodshed and destruction. The Paternova ordered the two houses involved to be declared outcast. While House Malaspina was eventually allowed back into the fold after some years of penance, House Dakkar was stripped of all its assets and holdings and cast into the darkness between the Calyx Expanse and the ill-fated Mandragora Sector. What little is known of the returned House Dakkar suggests that they harbour a venomous hatred of the Imperium and their erstwhile brothers in the Navis Nobilite, and are determined to act in any way possible against the interests of both. Before their fall, House Dakkar started a tradewar with House Brobantis on Vorlese after the latter broke a betrothal due to the supposed dark fate of the Dakkar.House Davor-JarniHouse Der'Cel (Renegade) - A renegade Navis Nobilite dynasty, House Der'Cel was closely allied with the Navigator Chaos Cult, the Cyclopean Congregation. After they were declared Excommunicate Traitoris, for their involvement in the Sepphoris Secession, the House traveled to the Jericho Reach where they were contacted by the Congregation. The entire House converted to the Cyclopean Congregation and began using their ship, the high-liner the Via Infractus, to house a massive breeding program to increase the size of the cult.House Enebayar (Nomadic House) - A nomadic house famous for the speed and relative reliability with which they navigate the Warp, the Enebayar regularly serve various Chapters of the Adeptus Astartes, several Knight houses, and the Navis Imperialis with distinction. Many mercantile factions have desperately tried to acquire the services of an Enebayar Navigator, to no avail.House Ferraci - This house has been in a long-running feud with the mighty House Belisarius.House Gibran - Members of this powerful house occupied the positions of both Paternova and Paternoval Envoy in mid-32nd Millennium during the War of the Beast.House Granicus - This Navigator House is notable for being one of three Navigator Houses who work exclusively for the Adeptus Astra Telepathica, providing Navigators for their fleet of Black Ships.House Grigoris (Renegade) - This dynasty's service in the Imperial Navy stretches back to the Age of Apostasy, as their household was renowned for producing Navigators of distinction. When the Achilus Crusade was formed, a majority of its household members traveled with the crusade to the Jericho Reach to serve as Navigators aboard the Imperium's vessels. Their fortune changed when Kokabiel Grigoris, a member of their house, turned against the Achilus Crusade and the Imperium after the ship he served on was lost in the Hadex Anomaly. Years later the ship reemerged, commanded by the now-mad and traitorous Kokabiel, and began preying upon the crusade's vessels. Kokabiel's heresy brought shame and scrutiny upon House Grigoris and caused Lord Militant Solomon Tetrarchus to order all of the house's members recalled from active duty, pending a full investigation by the Ordo Malleus. In the 41st Millennium only three members of the house were accounted for and returned. Kokabiel was the founder of the vile Chaos Cult known as the Cyclopean Congregation.House Hals-ViatiHouse HelmsburgHouse JenassisHouse Korshad - A formal house that puts business before all else, Korshad cares not who or what they ferry, so long as all forms are properly signed and appropriately marked. The Korshad are known to serve many Rogue Trader dynasties, but especially the Iaysus.House Laryx-Nor (Magisterial House) - An old house firmly connected to the Adeptus Mechanicus. Wildly flamboyant, they travel with retinues of beautifully ornate advanced servitors and highly sophisticated cherubim, all of which are clad in brilliant red chrome masks and sparkling silver plating.House LocarnoHouse Malaspina (Shrouded House) - This particular Navigator House has always been held in a measure of distrust by certain bodies of the Imperium. While the matter is not common knowledge, not a single Space Marine Chapter of the First or Second Foundings ever allows a Malaspina Navigator to operate on their vessels, nor do they ever embark upon a starship navigated by a scion of House Malaspina. The reasons for this prejudice are unknown even to the most senior members of the Adeptus Terra and the Ordos of the Inquisition, though a few suspect that the house's tenebrous origins lie in the shrouded past of the cataclysm known as the Horus Heresy. Since that distant time, House Malaspina has striven to expand its fortunes, though it has never truly succeeded in doing so.House MacPherson - This Navigator House is notable for being one of three Navigator Houses who work exclusively for the Adeptus Astra Telepathica, providing Navigators for their fleet of Black Ships.House Mercator (Shrouded House) - Very little is known of this mysterious Navigator House, for it deliberately keeps very much to themselves. They maintain very few obviously grandiose holdings. Over the millennia, the scions of House Mercator have come to be regarded as cursed in some manner, though not in any way that can be easily defined or because they have suffered some obvious misfortune. Rather, the house's name simply appears to be linked to numerous others who have met their doom beyond the borders of the Imperium, from the grandest Rogue Trader dynasties to the most far ranging Explorator fleets. Because of their veiled past, the Navigators of House Mercator exist in a shadowy world of service and espionage. Agents of this ill-starred house have learned of House Ortellius' misfortunes in producing viable gene-stock, and their masters are actively using this knowledge in exchange for information useful to their own shrouded interests.House M'ediciHouse Modar (Shrouded House) - House Modar is one of three ancient Navigator Houses that form a powerful triumvirate that traces its roots all the way back to the conquest of the Calyx Expanse by the Angevin Crusade over a thousand standard years ago. Houses Modar, Yeshar, and Rey'a'Nor earned a special place in the history of the region. They served with such honour and distinction during the Angevin Crusade that each secured its fortunes within what became the Calixis Sector for generations to come.House Nostromo (Renegade House) - Nostromo is an ancient and notorious Navigator House whose fate has ever been entwined with that of the Rogue Traders of the Haarlock Dynasty. Ever since the reforming Ecclesiarch Sebastian Thor himself bestowed upon the Haarlocks their Warrant of Trade, the line had been served by Navigators of House Nostromo. Despite its links to such a glorious dynasty, the House of Nostromo has ever been considered ill-starred.House Numa (Magisterial House) - An ancient Navigator dynasty based in the Navigator's Quarter on Terra, House Numa has maintained an allegiance with the Terran noble dynasty of House Draik, the ancestral family of Rogue Trader Janus Draik, since time immemorial.House Ortellius (Magisterial House) - A substantial rival of House Visscher both in wealth and status, this Navigator House's holdings in the Calixis Sector and the Koronus Expanse are far more visible to the populace at large. But over the last two or three generations their Navigators have slowly withdrawn from those regions' Warp routes. This decline has largely gone unnoticed, but most would conclude that Ortellius has merely taken up more lucrative positions in the Koronus Expanse and elsewhere. But the truth is much darker, for around a standard century ago, it was discovered that the purity of Ortellius gene-stock has substantially declined, and by the close of the 41st Millennium it was likely that the house would be unable to sire any viable offspring at all. House Mercator, however, has learned of House Ortellius' misfortunes and its masters are actively using this knowledge in exchange for information useful to their own shrouded interests. Ortellius continues to prepare for the coming political storm, when House Mercator reveals the truth, and countless rivals are likely to descend upon them in what will surely be the bitterest war of the house's long history.House Ptolemy - This Navigator house is notable for being one of three Navigator Houses who work exclusively for the Adeptus Astra Telepathica, providing Navigators for their fleet of Black Ships.House Rey'a'Nor (Shrouded House) - One of the three ancient Navigator Houses that forms a triumvirate that traces its roots all the way back to the conquest of the Calyx Expanse by the Angevin Crusade over a thousand standard years ago. Houses Rey'a'Nor, Modar and Yeshar earned a special place in the history of the region. They served with such honour and distinction during the Angevin Crusade that each secured its fortunes within what became the Calixis Sector for generations to come.House SixtusHouse Tarquinius (Renegade House) - A Renegade house of vile repute, Navigators of House Tarquinius ply their trade moving questionable cargoes for secretive interests. The house claims to abhor the Ruinous Powers and the rotting Imperium alike, but this has hardly spared them the ire of the Inquisition and their fellow Navigator houses. Thus far they have survived in large part by working with criminal organisations and certain planetary governors wishing to avoid the attention of the Imperium at large. They are even rumoured to work with some of those declared Hereticus Absentia, who fled the Imperium's rule during the Macharian Crusade.House TrueHouse Typhon (Renegade House) - Once a mighty Navigator house, House Typhon has fallen as far as it is possible for a Navigator house to fall. Even before its fall from grace, House Typhon was known to have associations with a variety of undesirable factions within the Imperium's vast institutions, having links to a number of Radical Inquisitors, of which several were Excommunicated. Its last Novator, Orthrus, is said to have delved into realms thought forbidden to the bulk of Humanity. Over time, Orthrus forged his own school of vile philosophy, coming to believe that the Navigator Gene represented the only true and ordained path for the human future. The foundations of what would eventually become known as the Elutrian Confederacy were laid in this way and the doom of House Typhon was ensured.House Visscher (Magisterial House) - One of the most ancient Navigator houses operating in the Koronus Expanse, House Visscher maintains extensive holdings across the entire segmentum and its palace on Terra in the Navigator's Quarter is held to be one of the finest ever built. Despite its wealth, this Navigator House is not well-known outside the Navis Nobilite. This is due to the manner in which it has amassed its fortune by specialising in clandestinely gathering new astropathic data by serving great Rogue Trader dynasties and far-ranging Explorator fleets.House Xan'Tai (Nomadic House) - This Navigator house now enjoys the favour once the preserve of Angevin's inner circle of Navigators within the Calixis Sector. Xan'Tai has negotiated an all-but exclusive charter to provide its best Navigators to Battlefleet Calixis.House Yeshar (Shrouded House) - One of three ancient Navigator houses that forms a triumvirate that traces its roots all the way back to the conquest of the Calyx Expanse by the Angevin Crusade over a thousand years ago. Houses Rey'a'Nor, Modar and Yeshar earned a special place in the history of the region. They served with such honour and distinction during the Angevin Crusade that each secured its fortunes within what became the Calixis Sector for generations to come.House Zegenda (Renegade House) - House Zegenda used to be one of the oldest Navigator Houses on record, having served the Imperium since the beginning of the Great Crusade. The Emperor of Mankind Himself gifted the entire house to one of His gene-sons, the Primarch Mortarion of the dreaded Death Guard Legion. Having spoken unbreakable oaths to serve the Death Guard onto perpetuity, House Zegenda subsequently followed its direct masters into rebellion, a betrayal that only ended in its death. The Astartes of the Death Guard suddenly turned on their loyal servants when First Captain Calas Typhon sought to portray them as traitors to cover his own betrayal of Mortarion in his quest to bring the Death Lord and the rest of the XIVth Legion into the service of Nurgle by stranding them within the Warp. As part of this ruse, each and every member of the house was executed aboard the starships they guided shortly before the beginning of the Siege of Terra. After their turn to the service of the Plague Lord, the fleets of the Death Guard no longer needed the aid of Navigators to find their way through the Warp.
