Mortifactors - Notable Campaigns: 9th Black Crusade (537.M38) - The 9th Black Crusade was a Black Crusade led by the infamous Chaos Lord Abaddon the Despoiler and his Black Legion, launched out of the Eye of Terror in 537.M38. When the Mortifactors and Lamenters Chapters responded to the desperate plight of the Hive World of Corellia, the superstitious-bound Mortifactors refused to fight alongside this darkly fated Chapter, leaving the Lamenters to defend the Hive World's population against the onslaught of the Black Legion Chaos Space Marines for six standard weeks, until the White Scars and the Ultramarines Chapters were able to break through the Chaos warfleet to relieve Corillia.Achilus Crusade (777.M41-Unknown Date.M41) - The Mortifactors Chapter has served in the Jericho Reach on three separate deployments amongst the ash-choked forests of Ravacene in the Greyhell Front of the Achilus Crusade. There, the Mortifactors took to smearing themselves in the volcanic ash that coats every surface, the better to stalk the haunted glades undetected. It is said that when the Mortifactors discovered the Kroot's propensity for consuming the flesh of the fallen, they were enraged, viewing the aliens' grisly practices as an insult to their own rites of respecting the remains of the dead. Several Mortifactors have become adept in the ways of the Kroot and served in the Deathwatch, where their skills and knowledge can be put to the most effective use. Several of these battle-brothers have retained the habit of smearing themselves in volcanic ash taken from Ravacene, though they ordinarily limit this to just their faces, granting them a pale, ghostly aspect.Chapter Dispute (819.M41) - A perceived slight caused the Mortifactors and Crimson Fists to come to blows. Only a personal intercession by Marneus Calgar, the Chapter Master of the Ultramarines, ended the dispute before it escalated to open war. The matter was kept from the attention of the Adeptus Terra.Battle of Rhorsch (Unknown Date.M41) - The world of Rhorsch was infested first by Blood Cults -- the Chaos Cults of Khorne -- and then by Khornate daemons themselves. The Mortifactors joined with the forces of the Raven Guard to destroy the daemons and eliminate the taint of Chaos from the planet.Tarsis Ultra Conflict (997.M41) - When the Tyranids from a splinter fleet of Hive Fleet Leviathan threatened the world of Tarsis Ultra, a planet under the sworn protection of the Ultramarines, the Mortifactors sent a company under Chaplain Astador to assist in its defence with their Strike Cruiser, the Mortis Probati, as they fought with the Ultramarines 4th Company and the Inquisition's elite Deathwatch Space Marines against the Tyranids' invasion of the world of Tarsis Ultra. This was the result of a renewal of the brotherhood between Captain Uriel Ventris of the Ultramarines' 4th Company and the Chapter Master of the Mortifactors, Lord Magyar. During the conflict, the Mortifactors showed themselves to be worthy Space Marines, albeit highly reckless for Astartes at times.Third War for Armageddon (998.M41) - The entire Mortifactors Chapter, all 10 companies, participated in the Third War for Armageddon.13th Black Crusade (999.M41) - The Mortifactors participated in the Chaeros taskforce during the 13th Black Crusade.Terran Crusade (ca. 999.M41) - The Mortifactors were one of the Ultramarines Successor Chapters who contributed forces to the resurrected Primarch Roboute Guilliman's Terran Crusade to return to Terra from Macragge so that he might meet with his father the Emperor for the first time in 10,000 standard years.War of Beasts (Unknown Date.M42) - The Mortifactors despatched 4 full companies to aid in the defence of the vital Imperial world of Vigilus from xenos forces and an assault by the Black Legion.Plague Wars (ca. 012.M42) - The Mortifactors contributed 3 companies to the "Spear of Espandor" campaign of the Plague Wars that resulted in the Loyalist forces retaking the Espandor System and cutting off the supply lines of the Nurglite invasion.
