M16

Humanity begins to colonise nearby solar systems using primitive sub-light spacecraft. At first progress is slow and the new colonies must survive as independent units isolated from Earth by up to ten generations of travel. The period of the next ten thousand years will later be known subsequently as the Golden- and Dark Age of Technology.

 

M21

Keeper Cripias records this as the end of the Golden Age. The Golden Race of Men (Terrans) becomes depended on the Stone Race of Men (Martians) and their artifices and as such the Stone Men prevail.  Sometime within the next 5,000 years the Men of Stone create the Iron Men (Robots and Titans) to help in the building of their Empire.

 

M21

Humanity explores and settles the galaxy following the discovery of Warp drives allowing more rapid dispersion, first alien races encountered. All done in less than 1000 years.

 

M21

Navigator gene isolated, Navigators are powerful psykers able to pilot ships through the warp, and so warp travel becomes even faster. Navigator families and cartels become powerful political entities.  The Expansion of Humanity covers most of the galaxy, Standard Template Construct (STC) system is perfected to aid new colonies. Titans are developed for rapid land movement.

M26

Keeper Cripias' history states that at this time, the Stone Men and Iron Men (now grown from servants to equals) fall into warring with each other.  The Iron Men have no soul and the Stone Men in the final acts of self-preservation, annihilate the Iron Men, including those who remain loyal, in battle.  Thus the Age of strife begins.

 

M26

Warp Storms isolate many parts of the galaxy including Earth and the Squat Home Worlds. This marks the beginning of the Squat Age of Isolation. The Home World mining colonies become self-sufficient, independent strongholds. During this period the Engineers Guild develops into a sociopolitical power and strongholds form complex political and trading agreements that become Leagues.

 

M26

The Cult Mechanicus is founded on Mars as a survival mechanism to maintain the technology necessary for life on the planet.  The Cult constructs their High Altar and builds their vast fighting machines based on Titan technology.  The Mechanicus spacecraft are unable to leave the Sol system.

 

M26

A slight abating in warp storms leads to encounters between the Squat Home Worlds and alien races known as the Age of Trade.  Squats use their tremendous mineral wealth to trade for weapons, foodstuffs, and high-tech systems with the Eldar and Orks.  During conflicts between the Orks and Eldar, the Squats remain neutral and maintain trade with both sides.

 

M26

Studying the pattern of warp storms, Mars prepares massive expeditions consisting of entire Titan Legions and thousands of servitors to explore the galaxy.  The successful colonies become the Forge Worlds and Knight Worlds of the Adeptus Mechanicus.  This process continues throughout the Age of Strife.

 

M27

A probe is dispatched from Terra, its mission to reach the utmost limit of the universe (14,000 years later it has yet to begin its return trip and many of the signals identified sent by the probe have been Orkish in nature).

 

M28

M28

Grunhag the Flayer, Ork Warlord attacks the Squat Homeworlds with a huge fleet.Many strongholds are wiped out by the Orks, the epic ballad "The Fall of Imbach" commemorates one such destruction. This marks the beginning of Squat hostility towards Orks and distrust towards Eldar who stayed neutral in the conflict. This marks the end of the Age of Trade and the beginning of the Age of Wars between Squats, Eldar and Orks.

 

M28

Earliest modified warriors aid the Emperor in conquest of Terra.

 

M29

Earth is reunited under a new leader (the Emperor), this warlord begins a slow push to the stars.  Upon his arrival on Mars, the Emperor is recognized as the Cult Mechanicus' Omnissiah of legend.

Fall of the Eldar: Eldar society teeters on the brink of Chaos and finally collapses, thus creating the Chaos god Slaanesh. Slaanesh's pyschic scream tears at the universe and all Eldar within thousands of light years are destroyed in an instant. A vast black hole opens and the Eldar worlds are consumed within it. Only a few of the fleeing Craftworlds furthest away from the epicentre survive. Today this black hole is known as the Eye of Terror. This rift caused warp storms to become passive and human worlds throughout the galaxy were brought into contact once more. The Age of Strife ended and mankind replaced the Eldar as the galaxy's most vital race.

Zaraphiston's visions show Abaddon the Arx Gap, a stable route out of the Eye of Terror that bypasses the heavily defended Cadian Gate.  Abaddon begins his Ninth Black Crusade by dispatching a vanguard fleet to destroy the Imperial monitoring station on Arx.  The assault on Arx wipes out the defending Imperial Guard and station crew. The scout frigate Ascendance receives a plea for help.  Reinforcements four months later find no survivors or sign of those responsible.  Inquisitor Horst investigates.

 

The Planet Killer is completed and a massive effort begins to find enough crew to man it.  Zaraphiston binds several daemons to the huge vessel, greatly reducing the manpower needed to run it.

Abaddon uses Savaven as a trial for the Planet Killer, destroying the planet along with its population in less than an hour.

 

144.M41

The Planet Killer arrives at Saviour, a highly populated system in Lysades sub-sector. After revealing the Planet Killer, Abaddon demands that Saviour's orbital docks begin producing ships for the Chaos fleet. The commander of Saviour has little choice but to agree, the lives of eleven billion people are at stake. With the threat of the Abaddon's Planet Killer, more and more worlds of the Gothic Sector surrender.

 

The Commander of Brinaga (in the Brigia system) receives warning that Abaddon may attack soon, in an attempt to capture Blackstone VI. All communications are lost with Brinaga shortly afterwards. A patrol vessel reports that the existence of Brinaga can no longer be confirmed.

 

Abaddon takes the Planet Killer to Fularis, where Blackstone I orbits Fularis II. While the captured Blackstone Fortresses destroy Fularis II.

The Lysades sub-sector of the Gothic Sector is almost entirely overrun by Chaos.

 

An Imperial patrol flotilla encounters the Planet Killer as it leaves warpspace, entering the Corain system. They attack immediately before the rest of Abaddon's fleet can arrive. After causing considerable damage, the Imperial fleet is finally driven off by the Planet Killer's immense arsenal. Abaddon's forces invade Corain VI and take over its mines. Loyalist guerrilla fighters report that considerable amounts of trikali crystal are shipped into orbit, where the Planet Killer is stationed. Trikali crystal is mainly used in the anti-magnetic containment fields of warp generators and plasma reactors.

Abaddon invades Drakulu system and enslaves the two million inhabitants of the system's main planet, an agri-world. It is widely believed that many of these end up as sacrifices for Zaraphiston's magics, the remainder forced into service as crews on the Planet Killer and other vessels.

 

150.M41

The Planet Killer under the command of Warmaster Malefica Arkham is dispatched to attack Arimaspia as a diversion.  Although Abaddon is defeated at Schindlegeist, the Planet Killer succeeds in destroying two of the five planets that make up the Arimaspia system.
