M32 to M35 Golden Age of Jericho - With the wider Imperium swelling to a peak of power and influence, the Jericho Sector is but one of many that bloom into a renaissance of power and achievement as scores of Imperial worlds of every type are raised up from the rubble of past failures and the un-trodden soil of alien worlds in Mankind’s name. The Jericho Sector becomes both a bastion and exemplar of Imperial civilisation and majesty carved from the cold wilderness of space with a burgeoning population that quickly soars into the hundred of billions. The Jericho Sector is a hub of Imperial commerce and industry with its bloody past all but forgotten, a realm of piety and devotion whose renown is such that it is spoken of on Terra as a gem of Humanity’s domains. Its goods are sought after as far afield as blessed Ultramar and distant Espandor. With the passage of millennia the power and fortunes of the Imperium wax and wane, but the Jericho Sector manages to remain strong and prosperous despite the vicissitudes of war, invasion, and petty disaster. However, the dawning of the 35th Millennium heralds both a darkening of the sector’s fate and the coming of the Deathwatch into the known histories of the Jericho Reach.

ca. M34 Imperial Cult Made Mandatory for Imperial Citizens - The High Lords of Terra join the Ecclesiarchy and make the Imperial Cult the official state religion of the Imperium of Man. From this point on, the worship of the Emperor of Mankind is mandatory for all Imperial citizens and the Imperial faith becomes widely admired as a potent form of social control.
101.M34 Noble Passing- While leading his Chapter to victory in the Bloodpox Campaign against the Death GuardTraitor Legion and the Brotherhood of the Plague, the twelfth Supreme Grand Master of the Dark AngelsChapter, the esteemed Armaros, contracts the loathsome pox known as Nurgle's Rot.

ca. 300.M34 - Ecclesiarch Greigor XI announces the Ecclesiarchy will return to Terra. Many object, but even after his death under suspicious circumstances, the return of the Ecclesiarchy's ruling Holy Synod to Terra proceeds.
401.M34 - 975.M35 The Nova Terra Interregnum in the Jericho Sector - During the Nova Terra Interregnum, the Imperium is dived into warring factions by civil war amongst the Imperial Commanders. During the centuries of battle and attrition that follow, the Jericho Sector (distant enough from the front lines to be spared direct contact with the conflict) is nevertheless a vocal and active supporter of the Terran Loyalists, channelling large volumes of manpower and resources to fuel the war. The drain of the sector’s resources becomes increasingly hard to sustain, leading to widespread shortages and unrest on many of the worlds of the Jericho Sector for the first time in living memory.
401.M34 The Howling - Space Marines of the Black TemplarsChapter end the Catelexis Heresy by executing the Cacodominus, an alien cyborg whose formidable psychic presence allowed it to control the populance of thirteen hundred planetary systems. Alas the Cacodominus' death scream echoes and amplifies through the Warp, burning out the minds of a billion Astropaths and distorting the signal of the Astronomican. Millions upon millions of ships are lost in the resulting upheaval and entire sub-sectors slide into barbarism without the dictats of the Adeptus Terra to guide them.
456.M34 In the Wrong Hands - Inquisitor Halleck, after many decades tracking degenerates in wilderness space, captures a mysterious Heretic known only as the Angel of Truth. The last Vox broadcast by Halleck's ship claims the prisoner has broken under questioning and revealed a deep-rooted heresy.

They report no sign of the Inquisitor, his vessel or the prisoner.
ca. Mid-M34 - The 8th Founding occurs during the middle of the 34th Millennium. This Founding of Astartes Chapters includes the Founding of the Mantis Warriors, in which the ancient text known as the Libris Gloriana speaks, "...the line of the great Khan, by his sons the Marauders." This suggests that the Mantis Warriors are of the White Scars bloodline as the Marauders were a 2nd Founding Successor Chapter of the White Scars.
666.M34 Lure of the Warp Stars - After a titanic Warp Storm roils out of the Eye of Terror, the first Warp Stars are sighted -- stellar anomalies whose unnaturally exact gravitational pull lures voidcraft and even small planets into their daemon-haunted embrace.
