Ultramarines 4th Company - Notable Defenders of Ultramar: Captain Uriel Ventris - Uriel Ventris is the current Captain of the Ultramarines 4th Company.Chaplain Judd Clausel - Judd Clausel is the Chaplain of the 4th Company of the Ultramarines. Clausel has fought alongside several leaders of the company, including Captain Idaeus, his successor Captain Uriel Ventris and Sergeant Learchus Abantes, who served as acting captain for a time. A straightforward and violent warrior, he is prone to headlong charges and is often depicted cutting enemies in two with his Crozius Arcanum. Clausel cares little for talk, and has reprimanded members of the Ecclesiarchy for discussing theology during meetings, and threatened Planetary Governors when they are slow to act. Uriel Ventris once stated, "Chaplain Clausel speaks bluntly, but he is right to do so."Apothecary Selenus - The long-serving Apothecary to the 4th Company, Selenus accompanied Captain Uriel Ventris on several of his early missions, including the battles on Pavonis and Tarsis Ultra. In the aftermath of the devastating action on Tarsis Ultra, and Captain Ventris' banishment from the Chapter, Selenus, along with Chaplain Judd Clausel, assisted Acting Captain Learchus Abantes in screening the company's new recruits and rebuilding the company's numbers. Selenus also accompanied the 4th Company on its reconnaissance mission to Espandor, where he was instrumental in retrieving the gene-seed of Ultramarines who had fallen on the frigate Guilliman's Honour, before their remains could be ravaged by Orks. After Ventris' reinstatement to the 4th Company, Selenus also fought alongside him during the company's second deployment to Pavonis. During the Invasion of Ultramar, Ventris appointed Selenus to his newly-formed Command Squad, the "Swords of Calth." Ventris reflected that, although his medical skills were great, Selenus was first and foremost a warrior, and his knowledge of the physiology of all species made him that much more devastating in combat. Selenus survived the desperate fight in the catacombs of Calth against the Iron Warriors Warsmith Honsou, and carried out Raven Guard Shadow Captain Aethon Shaan's request to extract the gene-seed of Ardaric Vaanes, a Renegade Raven Guard who had nonetheless sided with the Ultramarines during the final battle.Veteran Sergeant Pasanius Lysane - Lysane was a Veteran Sergeant of the 4th Company of the Ultramarines, and the best friend of Captain Uriel Ventris. Like Ventris, Pasanius was born on Calth, and the two boys grew up together. As Aspirants to the Ultramarines, the pair remained together throughout their training at the Agilesus Barracks and their subsequent service in the Ultramarines. Before his induction into the Space Marines, Pasanius was already a towering youth, and as an Ultramarine, his physique was so massive that his Power Armour had to incorporate salvaged pieces of Tactical Dreadnought Armour to fit his frame. His primary weapon was a Heavy Flamer.Sergeant Learchus Abantes - Abantes is cool-headed and follows rules very closely, as opposed to his superior Captain Uriel Ventris. Learchus is one of Captain Ventris' most trusted sergeants, who often consults him. While Ventris was exiled in the Eye of Terror, Learchus took command of the 4th Company as its Acting Captain. On Ventris' return to command of the company, Learchus grew jealous, feeling that he had earned the right to command the company. Ventris was forced to remind him that the company remained his to lead. After this dispute broke out into the open, Learchus, to his credit, made clear to oppose any remaining doubt of Ventris within the company or Chapter. Later during the second campaign on Pavonis, Learchus took command of a Scout Squad and infiltrated the port of Praxedes, distracting the T'au long enough to allow the rest of the company's Drop Pods to safely land. On Calth during the Invasion of Ultramar, Learchus commanded an armored spearhead consisting of both Ultramarine and Planetary Defence Force vehicles. He attempted to stop an enemy convoy comprised of Warsmith Honsou's forces from reaching Guilliman's Gate, but was forced to retreat when a Traitor Baneblade appeared on the battlefield.Company Champion Petronius Nero - Nero currently serves as Company Champion in Captain Uriel Ventris' Command Squad, "The Swords of Calth." An exceptional close combat specialist, Nero first distinguished himself during the Second Battle of Pavonis as part of a raiding party infiltrating the T'au headquarters camp. Nero survived the collapse of the cavern engineered by the Warsmith Honsou, though he was grieved when his custom-made Power Sword was broken by the rockfall. As part of Ventris' Command Squad, Nero joined the defence of Calth from the invasion of the Bloodborn in 999.M41. When Ventris tracked Honsou to the underground tomb of Remus Ventanus, the Ultramarines were attacked by the Blade Dancers of Xiomagra. The Mistress of the Blade Dancers was far too fast for Uriel, but Nero stepped in and not only saved his life, but defeated Xiomagra with apparent ease.Captain Idaeus - Idaeus was the former Captain of the Ultramarines' 4th Company, who died shortly after passing his position on to his senior Sergeant, Uriel Ventris. Unusually for an Ultramarine, Idaeus was a pragmatic thinker, adhering to the Codex Astartes only when he more or less needed to. He knew when to bend the rules of engagement and when not to, and trusted his gut instincts, even when every other sign told him things were going as planned. He was widely respected by the men of the 4th Company, although his senior Veteran Sergeant, Uriel Ventris, had difficulty accepting his deviation from the Codex, even after winning victories with him over several solar decades. Idaeus' last campaign was on Thracia, where the Ultramarines were helping the Imperial Guard suppress a Chaos-fueled rebellion. The 4th Company was charged with destroying a number of bridges that the enemy could use to outflank the Guard as it advanced on the rebel stronghold. As they were laying the charges on Bridge Two-Four, they came under attack by Chaos Space Marines of the Night Lords Traitor Legion. Although outnumbered and outgunned, Idaeus could not retreat and leave the bridges intact, so instead they held their positions. When the Night Lords advanced across the bridge, with the bodies of slain Ultramarines impaled on the front of their tanks, Idaeus' fury was terrible, and he led a countercharge that drove the Night Lords back. With only seven Ultramarines left of his original force, Idaeus handed his Power Sword -- which he had forged himself before the Corinthian Crusade -- to Uriel Ventris, clearly intending that the sergeant succeed his as commander of the 4th Company, then stormed off alone to detonate the remaining charges with his Plasma Pistol. He died in the midst of a squad of Chaos Raptors, who recoiled in terror as he set off the explosives. Idaeus' reputation for "unorthodox" thinking went beyond the Ultramarines Chapter; shortly after Ventris was promoted to Captain, Inquisitor Ario Barzano requested the 4th Company's assistance in traveling to Pavonis, confident that he needed someone capable of thinking outside the strictures of the Codex. After the conclusion of the first Pavonis campaign, Ventris remembered Marneus Calgar's advice to him, that Idaeus may have been a great man, but he would have wanted Ventris to be his own man as leader of the company. Feeling that he had accomplished this, Ventris decided that, instead of re-forging the blade of Idaeus's sword, which had been broken during the final battle of the Pavonis campaign, he would keep the hilt, but forge a new blade himself. After Idaeus' death, the artificers of Konor created a master-crafted Plasma Pistol named in his memory.Captain Remus Ventanus - Remus Ventanus was the Captain of the Ultramarines Legion's 4th Company during the Great Crusade and the Horus Heresy. His actions during the Battle of Calth helped save the planet from complete destruction, cementing his status as an Ultramarines hero even into in the late 41st Millennium. His tomb on Calth became a major site of pilgrimage for the Ultramarines and the people of Ultramar, and played a key role in the victory of the Ultramarines over the forces of Chaos during the Invasion of Ultramar.Ancient Cessio (KIA) - The warriors of the 4th Company tell proud tales of Ancient Cessio, who earned his title engaging the insidious Genestealer Cult infesting the Hive City of Chanchados on Ponides III. Driven back to their last redoubts, the screeching cultist hordes threw themselves at the Ultramarines in a sudden and viciously synchronous counterattack. When the Company Ancient's skull was cracked open by an Aberrant's lumpen power hammer, it was Cessio who took up the company standard before it could fall. With a great cry of defiance, Cessio rallied his brothers, and they smashed into the cultists with a crunch of ceramite against flesh. Still holding the banner aloft, Cessio met the cult's monstrous Patriarch in single combat. Its lashing claws rent the Ancient's armour. Its psychic powers ravaged his mind. Yet with his dying breath Cessio lopped the monster's head from its shoulders and perished with the standard still propped aloft.
