Editing Remus Ventanus (section)

==Horus Heresy==

[[File:Remus Ventanus.jpg‎|240px|thumb|right|For the model to be 100% accurate both the standard and one of his boots should be planted squarely in a Word Bearer's ass.]]

Captain Ventanus was present during the muster on Calth, believing that his legion and the [[Word Bearers]] were about to go kill [[Orks]] together and make up after what had happened at Monarchia. He was put in charge of overseeing the Erud regional muster, which he suspected was Guilliman's way of teaching him to do something other than kill shit, since the primarch believed that his Astartes had to have ''some'' kind of retirement plan once the Crusade was over. He was discussing a labor shortfall with some of the local officials of Numinus City when the Word Bearers launched the fleet tender ''Campanile'' through the planet's largest orbital dockyard and began massacring the unsuspecting Ultramarines on the planet and in orbit. He and his sergeant, Kiuz Selaton, narrowly avoided being killed by some marauding Word Bearers and set about trying to sort out what was going on. Along the way he found a legion standard in the hands of a dead Ultramarine, its shaft twisted by the Marine's death spasms, and took it along with him, [[awesome|using it as an improvised weapon]].

He and Selaton were almost cut off and killed inside Numinus, but were saved by skitarii forces under the command of Magos Meer Edv Tawren and Master Arook Serotid. They were able to reestablish contact with Captain Sydance out at the Erud muster and reunite with him and what remained of the Fourth Company at the Leptius Numinus palace, which had a cogitator unaffected by the Chaos scrapcode the Word Bearers had infiltrated into the Calth noosphere. They made contact with more skitarii, Ultramarines, and Imperial Army elements along the way, assembling a sizable force under Ventanus' command. The Word Bearers eventually assaulted the palace, but were defeated. Their commander, Morpal Cxir, provoked another Ultramarine captain into killing him after he'd surrendered, which allowed [[Samus]] to manifest and start wrecking shit. Ventanus banished the daemon with Cxir's athame, after which Magos Tawren then informed him that she had discovered a killcode formulated by her predecessor that would allow them to purge the scrapcode and retake control of Calth's defenses.

Ventanus left a token force to hold Leptius Numinus as long as possible and took the rest of his troops to a spaceport near the city of Lanshear that possessed a data-engine of sufficient strength to run the Calth defense grid. They were nearly wiped out by superior Word Bearer forces under Hol Beloth, until Ultramarine, Army, and Titan reinforcements arrived, vectored there by the junior magos who'd remained behind at Leptius. They held back the Word Bearers long enough for Tawren to deploy the killcode and clear the noosphere and for a kill team led by Roboute Guilliman to knock out the data-engine the Word Bearers were using to control the grid. With Calth now being battered by lethal levels of radiation from its poisoned star, Ventanus led an exodus into the planet's underground arcologies, swearing to purge every single Word Bearer still on the planet. During the ensuing [[Underworld War]], Ventanus served as one of the senior commanders of the loyalist forces, operating out of the newly renamed Arcology X. In gratitude for his leadership and skill, the civilian survivors began calling him the "Saviour of Calth". Though he disliked the title, he accepted its use after Captain Sydance pointed out that viewing him in this light was a critical morale booster for the refugees. Ventanus led multiple surface assaults against the Word Bearers, wiping out several major groups, and narrowly averted Dark Apostle Maloq Kartho's attempt to destroy Arcology X with a virus bomb, also killing the XVII Legion Captain Hol Beloth in the process. He managed to mortally injure Kartho with an athame known as the Shard of Erebus; however, Kartho was able to ascend to daemonhood, becoming the daemon prince [[M'kar]].

Ventanus was retrieved from Calth some time later and became a senior advisor to Guilliman, helping him refine the treatise that would ultimately become the Codex Astartes. He discovered a flaw in one of Guilliman's tactical plans and pointed it out, whereupon the primarch told him that the Codex was meant to be a set of guidelines for Space Marines, not a dogmatic holy book to be followed without question. This lesson was lost on [[Matt Ward|some people]].
