Timeline of the Warhammer 40,000 Universe - Talledus War (Unknown Date.M42): The Talledus War was a War of Faith fought in the Era Indomitus between the forces of Chaos and the Imperium of Man to defend the Shrine World of Benediction in the Talledus System of the Veritus Sub-sector. Though Benediction was the Chaos forces' primary target, all the inhabited worlds of the system faced a large-scale assault led by the Dark Apostle Kor Phaeron of the Word Bearers Traitor Legion.The Word Bearers, as always, sought to convert the bulk of Humanity to the service and worship of the Chaos Gods. They took great pleasure in furthering this agenda by attacking a world and system that was of such importance to the Imperial state religion they deemed a fraud. The fall of Talledus and Benediction to Chaos, and the conversion of its people to the true faith of Chaos, were deemed a potentially major milestone in the Word Bearers' plan to throw down the Corpse God of the Imperium and claim Mankind for the Dark Gods.The war proceeded on three fronts, on Benediction, on the Astra Militarum Fortress World of Ghreddask and in the void surrounding the asteroid belt called the Tears of the Emperor at the very edge of the system.On Benediction, the Word Bearers forces commanded by Kor Phaeron nearly seized control of the Grand Honorificum cathedral-city complex. The Loyalists were saved by an unusual phenomenon that was part of the Psychic Awakening when the faith of those gathered in the cathedral summoned forth from the Warp the protective spirits of the sacred Imperial dead. This supernatural force, later remembered as the "Saints' Wall," surrounded the Grand Honorificum in a protective psychic shield and extinguished the grip on reality held by many of the Daemons making up Kor Phaeron's attacking army. This miracle allowed a demi-company of Salamanders Astartes to cut the remaining force of Chaos troops in two and establish a new defensive perimeter for the cathedral complex.On Ghreddask, the intervention of a Black Templars strike force destroyed the Soul Harvester mobile fortress-factory that had left the Imperial defenders at a loss, though the suicidal counterassault cost the life of the Astartes commander, Castellan Dramos.In the void, within the Tears of the Emperor, a piratical Night Lords fleet commanded by the Chaos battleship Nightmare of Celyx sought to draw in Imperial military and commercial shipping translating into the system from the Warp by using captured Imperial astropaths to throw off their Navigators' abilities. The Night Lords then took the spoils and reaped with great pleasure the terror of their victims.The arrival of Vanguard Marines from the White Scars' 10th Brotherhood turned the tables on the Heretic Astartes pirates. Their hit-and-run strikes soon transformed into a vicious, void-based guerilla war as each side tried to lure the other into ambushes. The White Scars succeeded in blunting the Night Lords' attacks on incoming Imperial shipping, but were unable to annihilate the Chaos raiding force entirely.Though the Imperium has so far managed to blunt the Chaos assault on the Talledus System on every front, the conflict is far from over.
