Dark Angels - Age of Forboding, M35-M36: Raid on Nova Terra (257.M35) - 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 the notorious Fallen Angel. A daring Ravenwing strike assaults Nova Terra, but fails to apprehend any prisoners.Hrakon Campaign (495.M35) - 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.Cataclysm of Souls (975.M35) - 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. Although the Unforgiven Chapters are seen as loyal by the wider Imperium, many dark rumours tell of the Angels of Redemption abandoning their duties to pursue their own veiled missions.Hrud Rising (980.M35) - 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. The Chapter Master of the Ultramarines files a complaint with the High Lords of Terra about the Dark Angels' behaviour, although no action is seen to be taken in response.Red Heresy (290-310.M36) - During the Age of Apostasy, the Red Heresy Plague erupts deep in the Segmentum Tempestus across the heavily populated star cluster known as the Don'lorth Sector, foreshadowing of the later battles that would become known as The Plague of Unbelief. It is here that the Cult of the Old Gods rises. Agitators and anarchists stir up the hives into open rebellion. Workers in their untold billions are urged by red-robed priests to cast off their shackles, to reject the corpse-god Emperor. The horrific slaughter of all agents of the Adeptus Administratum and Adeptus Ministorum is enough to draw in vast fleets of Imperial armed forces. Seeking a quick way to end the rebellion, the Silver Skulls Chapter deploy en masse in a desperate attempt to kill the leaders behind the rising cult. The hunt is disastrous -- with Drop Pod assaults ambushed and multiple Thunderhawks brought down en route to their objectives. Only the arrival of Dark Angels Deathwing and Ravenwing forces, along with the 3rd Company of the Angels of Vengeance, staves off certain defeat. However, the Silver Skulls observe the Deathwing forsaking the battle in pursuit of a mysterious robed Space Marine, which later turns out to be the notorious Fallen known as Cypher. Before Cypher escapes, an Angels of Vengeance Librarian detects several Fallen ensconced within the red-robed hierarchy of the Red Heresy. The Silver Skulls are left to dig themselves out of their own predicament. They do so, but openly condemn the Dark Angels; another formal protest is filed to the High Lords of Terra.Trail of Unbelief (314.M36-334.M36) - The Dark Angels begin a two-solar-decade-long campaign beset with many battles to hunt down Brother Machius, a former lieutenant of Cardinal Bucharis during the great rebellion known as the Plague of Unbelief. Despite several ambushes set by the Night Lords Traitor Legion, the Dark Angels prevail -- the Ravenwing locate Machius on th plague-ridden world of Gronmoth, capturing him at the Battle of Black Death.Rebulus Cleansing (439.M36) - Following a mysterious trail, the Dark Angels and several of their Successor Chapters begin a 30-year campaign that uproots hidden cults and corrupt officials across three sectors of Imperial space. The battles against this network of subversion bring much suffering to the Rebulus System before the corruption is finally subdued, culminating in the destruction of the artificial moons surrounding the planet Ixx.Siege of Dominus Prime (673.M36) - The Dark Angels and the Angels of Vengeance both deploy their entire 1st Companies to end the five year deadlock in the Imperial assault against a rebel tyrant. Nigh on two hundred Terminators crack open the "unassailable" fortress and massacre the Traitors. In truth, the Unforgiven's numbers were substantially higher, and several prisoners were taken back to The Rock for questioning.
