Pre-Imperial

Much of what has happened in this part of space has been lost in the fires of the Macharian Crusade, much purged deliberately as it were the records of Xenos.

Date Event Notes
Late M23 First Human settlement At the very end of the Dark Age of Technology, the first human colonies are established in the Eressa Sector. The Rebellion of the Men of Iron and the Age of Strife quickly cut them off from the rest of Humanity. Few, such as Animos survive.
M24 Knights of Eressa Prima Cajalax Maxia is inhabited just before the warp storms separate humanity amongst the stars.

M41

Defined by the Macharian Crusade and the subsequent Heresy, the first half of M41 was dominated by unparalleled glory and nearly equal despair when Warmaster Solar Macharius first covered over 1000 worlds, only for his 7 generals to fall into battle against each other upon his death.

Date Event Notes
392.M41 Begin of the Macharian Crusade Under command of Lord Solar Macharius, a force of nearly a dozen regiments and several Space Marine Chapters set out to conquer the western fringe of the galaxy, bordering the Halo Stars.
397.M41 Annexation of Beyonne The planet Beyonne is claimed by Macharius forces and becomes a first pivot for supply routes within the Eressa Sector. Later, as the fronts move further away, soldiers on leave gather there in uncounted numbers to indulge in worldly pleasures.
398.M41 Conquest of Chodounska Among the latest worlds conquered in Eressa, Chodounska was planned to support the advance into the Halo Zone, an operation that never happened. The fate of the planet's nearly limitless stock of supplies and weaponry is currently unknown.
399.M41 End of the Macharian Crusade Exhausted and faced with the horrors of the Halo Zone, Macharius' men refused to follow their commander into this dreaded part of space. His dreams of conquest shattered, Macharius ordered the return to imperial space.
