0. The Beginning of Silence (999.M41 – 001.M44)
Sector: Nachmund Gauntlet
Threat: Chaos Forces
In the closing year of M41, the Nachmund Gauntlet ceased to function as a reliable warp corridor. Chaos forces did not merely raid the region but established a persistent presence along its critical transit routes. Key systems fell in rapid succession, while warp anomalies and daemonic manifestations rendered navigation increasingly impossible.

Multiple Imperial counteroffensives were launched during the early years of M42. Though initial gains were recorded, all attempts to secure lasting control failed. The warp within the Gauntlet proved unstable and self-reinforcing, collapsing established routes and isolating Imperial task forces. Losses mounted, and recovered fleets reported severe temporal distortion and widespread navigational failure.

By 001.M44, the Nachmund Gauntlet was formally designated as strategically non-viable. No further large-scale liberation efforts were authorised. The remaining passages were deemed impassable to Imperial vessels, effectively severing sustained contact between Imperium Sanctus and the regions beyond.

Thus began what later records would name the Age of Silence, not marked by sudden annihilation, but by the gradual absence of response, reinforcement, and command.

1. The Aftershocks of the Great Sundering (999–012.M42)
Sector: Noctyrix Reach
Planets: Helior Prime, Vaskyre
Threat: Warp storms, isolation
After the opening of the Rift, the Noctyrix Reach was effectively torn apart. Helior Prime vanished from all charts for months, while the moons of Vaskyre quite literally drifted from their orbits. In the decades following the Rift's emergence, warp routes collapsed in waves. Entire sectors disappeared for months at a time, only to re-emerge later, often looted, warped, or rendered completely uninhabitable.

2. The Decade of the First Lost Stars (010–080.M42)
Sector: Ashkar Expanse
Planets: Lothrain, Kheled IX
Enemy: Ork raiding fleets
Numerous agri-worlds and mining worlds were abandoned. There was no resupply, no Astra Militarum reinforcement, only the local PDF and faith. Most of these worlds were never reclaimed. Kheled IX was completely stripped bare by the Orks before the system's defences finally collapsed.

3. The World of the Threefold Siege (064–071.M42)
Sector: Reductus Verge
Planet: Mornath
Enemy: Chaos renegades, Drukhari raiders, Ork freebooters
The strategically vital world of Mornath was attacked from three directions simultaneously, each force acting independently. Seventy percent of the population perished before the Imperium resorted to burning its own cities and continents to prevent total occupation.

4. The Crusade of Reclaimed Ashes (102–148.M42)
Sector: Sable Marches
Planets: Thraxos, Pellion
Enemy: Chaos cultists, heretical PDF
Several lost worlds were reclaimed over decades through slow and brutal campaigns. The reconquest of Thraxos became legendary, but the population of Pellion was never restored,though the banner of the Imperium flew once more.

5. The Silent Plague (121–134.M42)
Sector: Verdanth Coil
Planets: Ilyr Secundus, Morwen
Threat: Unknown biological affliction
There was no mutation, no visible panic of contagion, the population simply collapsed and never rose again. An illness of unknown origin paralysed entire systems. It was not dramatic, not grotesque… life simply stopped. Billions died before it faded away, vanishing as suddenly as it had appeared.

6. The Broken Crusading Oath (170.M42)
Sector: Caligorn Depths
Target Planet: Eremiel
Enemy: Unknown (suspected Chaos influence)
A major crusade was solemnly proclaimed, yet the fleet never reached Eremiel. Wreckage emerged decades later along the fringes of the warp.

7. The Wars of Faith (200–260.M42)
Sector: Sancta Umbra
Planets: Seraphine's Fall, Orthis
Enemy: Imperial heretics against one another
With communication shattered, divergent interpretations of the Imperial Creed arose. On several worlds, armed conflict erupted solely because prayers were spoken differently. Both sides were killed in the name of the Imperium.

8. The System Defended in Blood (233–289.M42)
Sector: Baelthorn Cluster
Planet: Baelthorn Prime
Enemy: Chaos Space Marine warband
The planet never fell, but only because it endured continuous warfare across generations. Half the population never knew peace, growing up beneath perpetual siege.

9. The Age of Warp Shadow (300–360.M42)
Sector: Gloam Riftward
Planets: Nyxara, Velos
Threat: Massive warp anomaly
A vast warp anomaly sealed off entire sectors. Ships vanished, stars appeared to shift in the heavens, and on some worlds even the perception of time was distorted. Reports claimed decades passed in days… or the reverse.

10. The Attempted Second Reconstruction (390–420.M42)
Sector: Obsidian Halo
Planets: Carthis, Malvernis
Threat: Internal collapse, resource scarcity
A large-scale reorganisation was ordered by Dante. It proved a partial success, and a partial failure. The strongest worlds endured; the weak disappeared.

11. The Black Decade (460–470.M42)
Sector: Multiple sectors affected
Planets: Unknown / records expunged
Threat: Unknown
At this point, Administratum archives simply… fail. Almost no official records survive, only fragmented reports, distress calls, and silent worlds.

12. The Late Return (510–560.M42)
Sector: Pale Crossing
Planets: Ithren, Caelos
Enemy: Cultural and religious deviation
Several worlds long believed lost unexpectedly re-established contact. Their populations were profoundly altered, culturally and spiritually. They no longer recognised the Imperium as it once was.

13. The Age of Star Graves (600–680.M42)
Sector: Ironwake Drift
Planets: Multiple wreck systems
Enemy: Xenos raiders, scavenger fleets
Entire fleets were annihilated in neighbouring systems. Vast debris fields remain dangerous, yet rich in strategic resources. Whole star systems became ship graveyards.

14. The Nameless Great Battle (702.M42)
Sector: Veiled Scar
Planet: Redacted
Enemy: Mixed Chaos and xenos forces
A battle everyone knows of, yet no one names, and no one speaks about. Multiple Chapters, multiple armies, and unimaginable losses.

15. The Third Dark Surge (740–820.M42)
Sector: Blackwake Reach
Planets: Reth, Solcar
Enemy: Chaos invasions, daemonic manifestations
Renewed Chaos and xenos assaults followed, as though the Rift itself had drawn breath once more. Several recently reclaimed worlds fell again, lost for a second time.

16. The Age of the Weary Regent (850–950.M42)
Sector: Entire Imperium Nihilus
Threat: Strategic exhaustion
Dante still lived. Dante still ruled. Yet more and more decisions were delegated. He became a legend even before death.

17. The Day of a Thousand Years of Isolation (999.M42)
Sector: Variable
Threat: Crisis of faith
On some worlds it was a day of mourning, on others of fanatic celebration. Exactly one thousand years had passed without contact with Terra. Many no longer believed it truly existed.

18. The Century of False Hope (010–090.M43)
Sector: Starfall Verge
Planets: Elthos, Mirayn
Enemy: Internal uprisings, false prophets
Rumours spread that Imperium Sanctus was approaching. Most were lies or misunderstandings, yet they ignited rebellions and waves of religious ecstasy.

19. The Wars of Survival (120–400.M43)
Sector: Scattered war zones
Enemy: Anything that moved
These were not wars of conquest, but of survival. Worlds fought merely to retain the right to call themselves Imperial.

20. The Age of Attrition (400–460.M43)
Sector: Dimming Reach
Planets: Harrowden, Kallith
Threat: Supply collapse, rebellion
There was no great invasion. People, food, and faith simply ran out. Several worlds collapsed for purely administrative reasons.

21. The Nameless Pilgrim Fleets (470–510.M43)
Sector: Sanctum Drift
Planets: Variable
Threat: Religious fanaticism, anarchy
Vast civilian fleets set out "towards Terra", though none knew where it lay. Many never arrived. Others destabilised entire systems.

22. The Second Warp Shadow (520–580.M43)
Sector: Gloam Riftward (again)
Planets: Nyxara, Threnos
Threat: Warp-time distortion
On some worlds, three different M43 date systems were used within a single generation. Chronologies became irreparably confused.

23. The Campaigns of the Broken Shield (590–650.M43)
Sector: Ironwake Drift
Planets: Varn, Cythria
Enemy: Ork warbands, renegade fleets
An entire defensive line collapsed, not all at once, but piece by piece.

24. The Evacuation of the Stars (660–710.M43)
Sector: Ashkar Expanse
Planets: Multiple evacuated worlds
Threat: Approaching, unidentified dangers
Entire planets were evacuated as a precaution. Many were never resettled.

25. The Third Reorganisation (720–780.M43)
Sector: Obsidian Halo and surrounding regions
Planets: Carthis, Malvernis
Threat: Internal power struggles
New command structures, new ranks, new doctrines, and endless conflict.

26. The Decades of False Peace (790–860.M43)
Sector: Several stabilised regions
Threat: Superficial calm
Few major wars, many small disappearances. Only later did the depth of decay become apparent.

27. The Age of Foreboding (870–999.M43)
Sector: Entire Imperium Nihilus
Threat: Sense of impending change
Prophecies, ominous signs, and increasingly frequent warp anomalies. Everyone felt that something vast was approaching, yet none knew what.

28. The Two-Thousand-Year Silence (999.M43)
Sector: Entire Imperium Nihilus
Nature of Event: Symbolic, religious, political
Threat: Internal fractures
Exactly two thousand years had passed since Imperium Nihilus was severed from Terra. There was no central command, no unified ritual, yet, remarkably, the same acts unfolded across countless worlds. For a single standard day:
– vox networks fell silent,
– ceremonial batteries ceased firing,
– and many voidports closed entirely.
This was not a celebration. Nor mourning. It was a remembrance. Some worlds recited the names of lost systems. Others lit only candles. On certain planets, riots erupted, "If we endured alone for two thousand years, why obey now?" And on some worlds, Dante's name was spoken, not as a commander, but as a witness. One who had been there throughout.Many believe this day marked the end of an era, even if none dared say what followed.

29. The Age of the Present (001.M44)
Status: Imperium Nihilus endures
Reality: Terra remains unreachable
Imperium Nihilus still lives, wounded, twisted, yet alive. Terra remains beyond reach. Dante is still Regent. The darkness still lingers, and none know how long he can endure.

30. The Unwritten Age (001.M44-)
Sector: Entire Imperium Nihilus
Threat: Unknown... yet. What comes next is not yet recorded. Your story begins here.
