Shield-Captain - Post-Heresy Era: Maldovar Colquan - One of two Tribunes who currently serves in the Adeptus Custodes. Maldovar spent many standard years in service, holding vigil over the Emperor as a member of the elite Hetaeron Guard, the Companions of the Emperor. Following Itaelo's death during the Second Battle of Terra while battling the forces of the Blood God, Maldovar was chosen to replace him as Tribune. Tribune Colquan served as a liaison between the acting Lord Commander of the Imperium, Roboute Guilliman, and Captain-General Trajann Valoris. He later joined the assembled Terran forces and took part in Guilliman's Indomitus Crusade, to take the fight to the Archenemy. Tribune Maldovar led the Custodian contingen for well over a standard century and took part in many notable campaigns, including the Battle of Raukos, which signaled the end of the century-long Crusade. Guilliman was troubled by the Tribune's contempt for baseline humanity, a sentiment that was all too often shared amongst Colquan's fellow warrior elite. The Custodians had spent their lives guarding the Emperor, yet they had forgotten who the Emperor guarded in His turn. He chastised Colquan to be more forgiving.Heracleon - One of two Tribunes who currently serves in the Adeptus Custodes, Heracleaon is the current Master of the Hetaeron Guard, who oversees the personal security of the Emperor within the Sanctum Imperialis itself.Italeo - Italeo was one of two Tribunes who served in the Adeptus Custodes. He commanded the few Custodian forces that were abroad fighting the myriad foes of Mankind in holy warfare before the formation of the Great Rift. Italeo was mortally wounded during the Second Battle of Terra while fighting against a massive incursion of a Khornate daemonhost. He was succeeded by Maldovar Colquan as Tribune.Aadilus - A Shield-Captain of the Adeptus Custodes, Aadilus commanded Custodian Vertus Praetor forces against the Vostokh 7th Traitor Imperial Guard regiment during the Victorium Crusade sometime after the formation of the Great Rift.Andronitus - A Shield-Captain of the Adeptus Custodes, Andronitus was present when the newly resurrected Ultramarines Primarch Roboute Guilliman arrived at the Eternity Gate to speak to his father, the Emperor at the climax of the Terran Crusade. It was Andronitus who granted the Primarch permission to enter within the Sanctum Imperialis to commune with his father, but only if he entered alone.Hasturius Calaxor - A notable Venerable Contemptor Dreadnought who has served within the ranks of the Adeptus Custodes for millennia. When he was still living, Hasturius Calaxor originally served in the ancient Legio Custodes, and came to prominence during the Horus Heresy during the defence of the Imperial Palace at the Battle of Terra. He held the Enlightener's Stair single-handedly against the turncoat soldiers of the 9th Terran Wardens. It was he who also rallied the Gospodor Heavy Infantry with his inspiring examples of bravery, and led them to retake the Dome of the Architects from Dortha Kol's Sons of Horus Legionaries and finally drive Kol's warriors to destruction while felling the Traitor Warhound Titan Warp Jackal as well. These heroics saw Calaxor promoted to the rank of Shield-Captain, after which he led three further highly successful counter-offensives before the siege's end. He went on to earn many more names in the centuries that followed. After many millennia of faithful service, he finally fell in battle on the Dead World of Palathrix, his sheer force of will keeping him alive long enough to be interred within a Dreadnought sarcophagus. He became Venerable Ancient Calaxor, and assumed a new role within the Ten Thousand, becoming a living war engine and strategic advisor amidst the ranks of the Adeptus Custodes.Daryth - Daryuth was a Shield-Captain charged with capturing the Fallen known as Cypher, after his unexplained escape from the prison cells deep beneath the Imperial Palace in the wake of the Terran Crusade. Following a trail of fading clues, Shield-Captain Daryth and his men have pressed out into the stars to continue their mission. Now they enlist the aid of the Sisters of Silence, bringing a band of the elite Witch Hunters aboard their frigate, Sol's Arrow, before making the perilous crossing of the Great Rift. The presence of the Silent Sisters seems to calm the madness of the Empyrean, at least enough to aid the Custodians in making their dangerous journey into the Imperium Nihilus. Amidst the madness, their Augurs do not detect the heavily-shielded Space Marine Strike Cruiser that follows in their wake, its hull night-black and its insignia veiled.Yorta'karin DesmodagesAnatolyn Ganorth - A Shield-Captain of the Fury of Terra Shield Host, which defended the Imperial world of Elysia from invasion by Heretic Astartes, following the formation of the Great Rift. Led by Captain-General Trajann Valoris himself, Ganorth has been chosen to act as his naysmith and to fight valiantly at Valoris' right hand.Rothrian GanythTybanus LencilusTybalus MaxinOldorian Mefistal - A Shield-Captain who serves in the Dread Host.Archturus Paliades - A Shield-Captain who currently commands the Gilded Talons Shield Company.Nathadian Steale - A Shield-Captain of the Fury of Terra Shield Host, which defended the Imperial world of Elysia from invasion by Heretic Astartes following the formation of the Great Rift.Thetus - A Shield-Captain of the Solar Watch, he led a Shield Company that purged a cabal of xenos flesh-witches on Yorlos.Heraclast Vadrian - Following the formation of the Great Rift, Shield-Captain Vadrian became concerned over the continual decline of the Golden Throne's functions and the threat it posed to the Emperor's safety.

He gathered a band of his finest warriors aboard the Cruiser Scion of Argo, and set off following a lead that points to the lost Forge World of Morvane.Valerian - Valerian served as a Shield-Captain in the Adeptus Custodes as part of the Palaiologian Chamber of the Hykanatoi. While taking part in one of the Custodes' Blood Games, he was asked by Heracleon, the Tribune of the elite Hetaeron Guard, to join their order. Having long striven to become a member of the Companions, Valerian eagerly accepted this great honour. Led to the Last Door of the Sanctum Imperialis, he prepared himself to face the Hetaeron Guard's first trial -- to cross the threshold of the Last Door and enter the presence of the God-Emperor. But Valerian could not compel himself to step forward, and so he was returned to his former duties on the Outer Walls of the Imperial Palace. But he would later make up for his perceived shortcomings when he helped to valiantly defend the Palace defences during the mayhem and madness that ensued following the aftermath of the formation of the Great Rift and the subsequent Battle of Lion's Gate.Kalim Varanor - Kalim Varanor was an Aquila Commander of the Adeptus Custodes who welcomed the newly resurrected Ultramarines Primarch Roboute Guilliman's arrival on Terra with all honour, and permitted the Primarch his audience with the Emperor.
