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. Early M35 - Warp storms activity sharply increases over the entire Imperium, and anarchy descends upon isolated worlds.
104.M35 Raid on Nova Terra - The Dark Angels, following Cypher's trail, are led to believe that at least one member of the newly declared Ur-Council of Nova Terra is a Fallen Dark Angel. In a daring raid, a Ravenwing strike force lands upon Nova Terra but fails to secure any prisoners.
267.M35 The First Martyr - The first known accessible Imperial record pertaining to the Deathwatch's Watch Fortress Erioch in the Jericho Sector appears at this date: Balthazar Ho’Tsun, Master of the Watch, Captain of the Imperial Fists, died in an action in the Slinnar Drift. The enemy engaged by the Deathwatch and the other forces involved were not recorded.
344.M35 - Initial Imperial surveys of Tomb complexes on Angelis (Gorkamorka) Later in the 35th Millennium, OrkSpace Hulk crashlands on Angelis, burying the humans alive around the temples.

495.M35 Hrakon Campaign - The Segmentum Pacificus is the centre of unrest during the Nova Terra Interregnum and the Chapter's Inner Circle continues to follow the many clues that have led them deep into the internecine fighting in the region. Known to the Dark Angels as the Hrakon Campaign, they systematically seek out Obidiah Hrakon, the despot ruler of an upstart planet which has been pivotal in its support of Nova Terra. In the Veiled Region, the Dark Angels finally corner Hrakon, who takes refuge on a piratical port world. Seeking to ensure that none escape, the Dark Angels blockade the planet and unleash the entire Deathwing. Deploying in sequential teleportations, the Terminators prosecute an epic slaughter until only a single foe is left alive -- Obidiah Hrakon -- once a Standard Bearer for the ancient Dark Angels Legion. Refusing to give up, Obidiah is subdued after a duel with the Grand Master of the Deathwing and is transported back to The Rock to face the tender mercies of the Interrogator-Chaplains. His death is not an easy one.

867.M35 Serpents of Menimshemash - On the EldarExodite world of Menimshemash, the daemons of Chaos enter through the "world spirit." This crystalline psychic network criss-crosses the world, joining all of the Exodite settlements and housing the souls of the dead from the last five thousand Terran years, much like a Craftworld's Infinity Circuit. Tzeentch's domain in the Realm of Chaos permeates the world spirit and erupts from its deep pathways; monstrouc crystalline serpents spew form waves of horrific daemons. The world is aflame with the fires of change before the next moon rises.
975.M35Cataclysm of Souls: The Ecclesiarchy begins to rebind the sundered Imperium during the Nova Terra Interregnum into a religious state that transcends political differences. Millions die in religious wars when the Ur-council of Nova Terra reject the Ecclesiarchy's teachings, unleashing a terrible new civil war.
975.M35 Dark Angels and the Cataclysm of Souls - Still operating largely in the Segmentum Pacificus during the Nova Terra Interregnum, the Dark Angels take part in the fierce fighting of the Cataclysm of Souls. In addition to putting down those who reject the authority of the High Lords of Terra and the Ecclesiarchy, they search for signs of the Fallen. It is a civil war the likes of which the Imperium has not seen since the Horus Heresy.
977.M35 A Fortress Breached - The Ultramarines' Battle BargeExcelsior is embroiled in battle when its Geller Field fails during translation from the Warp into realspace. The blessed metal of the titanic fortress-ship becomes permeable, and before long, a numberless tide of daemons pushes its way from the walls, floor and ceiling to fall upon the Ultramarines Astartes inside. Excelsior never rematerialises into reality.
980.M35 Hrud Rising - The Dark Angels take part in the task force cleansing the Hrud infestations that erupt across the Imperium at this time. With two of their three assigned sectors cleared, The Rock disappears as the Dark Angels leave the campaign to pursue their own objectives.

990.M35 The Burning of the White Palace - A series of Deathwatch Kill-teams are dispatched to the world of Vanir in the Jericho Sector and perform a surgical strike against the Imperial Planetary Governor and his administration. The Kill-teams purge the Governor’s palace of all life and then detonate a series of inferno devices that reduces it and the surrounding seven square kilometres of the planet’s surface to cinder ash. This event leaves an indelible mark on Vanir’s history, and enters the mythos of the native population of Vanir as the "Wrath of the Black Angels." This incident creates an enduring legend that survives even the later collapse of the planetary civilisation and into the present day.
