The writing of his memoirs spurred him to gather and write a full archive of his glorious career. However, this more candid memoir never sees the light of day, being immediately put under Inquisitorial seal by order of [[Inquisitor]] [[Amberley Vail]]. The archive simply contains far too much sensitive and restricted information. She organises the archive, naming it the [[Cain Archive]], and publishes it "for Inquisitors" only. A high number of Inquisitors read it. She is even persuaded to expand it considerably, making it somewhat of a bestseller among the [[Inquisition]].{{Fn|21a}}

==Trivia==
{{Trivia}}
*Earlier publications of [[Dark Imperium (Novel)]] took place roughly 100 years after the start of the Indomitus Crusade, and concluded at the [[Battle of Raukos]]. However in 2021 Black Library explicitly revised certain aspects of the novels, including setting the events to roughly 012.M42 as well as adding events from the [[Dawn of Fire (Novel Series)|Dawn of Fire]] series.{{Fn|47}}
*It is feasible that, given the secretive nature of the [[Inquisition]], the doubt as to whether or not the Indomitus Crusade takes place in M42 or M41 is knowledge that is limited to the [[Ordo Chronos]] and [[Roboute Guilliman]], and that the Galaxy at large simply moves on as if it were M42.{{fn|16c}} This would explain how other historians and even Inquisitors such as [[Amberley Vail]] would date events that occur during and after the 13th Black Crusade as M42.
{{Spoiler|source=Kill Team (Novel)}}
*Even Inquisitors themselves are not always adequately informed about galactic events at large. In [[Kill Team (Novel)]], [[T'au]] envoys are surprised when [[Inquisitor]] [[Oriel]] expresses that he and his retinue have no knowledge of the [[Damocles Crusade]].{{fn|48}} Amberley, despite being an Inquisitor herself, may not be awares of the Chronostrife.

==="M42"===
The millennium of M42 has been used by [[Games Workshop]] in various works, both from an out of character and in character perspective.
<br>
For an example of an in-character use, the events of the [[Second Siege of Perlia]] as part of the [[13th Black Crusade]] are confidently stated by [[Amberley Vail]] as having occurred between the years of 002.M42-005.M42.{{Fn|29d}} Similarly, she references multiple historical writers within the Imperium who have recorded the events of the siege from a later M42 date. These include:
*<sup>''[[In Blackest Night: The Millennial Wars Appraised]]'' by [[Ayjaepi Clothier]] in 127.M42{{Fn|29a}}</sup>
*<sup>''[[The Return of the Liberator: Ciaphas Cain and the Second Siege of Perlia]]'' by [[Orten Bassit]] in 037.M42{{Fn|29b}}</sup>
Given that Cain was also alive to fight the Second Siege of Perlia in the early years of M42, it would also, logically, lead to the reasonable assumption that his burial as referenced by Amberley{{Fn|44}} would also have occurred in M42. Similarly, in order to reference ''In Blackest Night: The Millennial Wars Appraised'' in her writings, Amberley herself would need to be alive as of the year 127.M42 at least.{{Fn|29a}}

For an out-of-character example, narrative events have also been hosted by [[Games Workshop]] subsidiaries, such as [[Operation Storm Falcon]] by Games Workshop Germany as explicitly taking 26 years after M42 and [[The Jollis Raid]] (which occured "at the end of the 41st Millennium".{{fn|45}}{{Fn|51}}{{GW-DEE}}

[[Image:Calgar Timeline Warhammer 40,000 Character Encyclopedia pg15.png|thumb|250px|<sup>A timeline of some major battles involving [[Marneus Calgar]]. Note that the [[Ultramar Campaign|Siege of Ultramar]] explicitly takes place in 999.M41.{{Fn|49}}]]
Furthermore, multiple sources confidently put several dates pertaining to the [[13th Black Crusade]] as being explicitly 999.M41. A non-exhaustive list of this includes:
*[[Ultramar Campaign|Siege of Ultramar]]{{fn|49a}}
*[[Siege of the Fenris System]]{{fn|49b}}{{fn|49c}}
*[[Devastation of Baal]]{{fn|49d}}
*[[Coheria|The Ritual of Coheria]]{{fn|49e}}
*[[Battle of Port Demesnus]]{{fn|49e}}

It would logically follow that any event that takes place a year or more after 999.M41 would be at least 001.M42 (or 000.M42) according to the [[Imperial Dating System#Year|Imperial Dating System]].

However, GW has also introduced the notion of doubt as to whether the events of the [[Era Indomitus]] truly are the 42nd Millennium or not. The emergence of the [[Great Rift]] has caused uneven temporal shifts across the galaxy, with time itself being affected.{{fn|46}} Twelve years after the start of the [[Indomitus Crusade]]{{fn|16d}}<sup>[[M42#Trivia|[See Trivia]]]</sup> the [[Primarch]] [[Roboute Guilliman]] made an attempt to determine the true date based upon the [[Imperial Dating System]] as laid out by the [[Emperor]] during the [[Great Crusade]]. This was, he notes, made ever difficult by over 10 millennia worth of both dogmatic adherence and thoughtless revisionism, as well as various rivalling dating systems which had evolved from the original Calendar, which made a true chronicle of the galaxy almost impossible to construct. To his consternation, he calculated that year to be "anywhere between early M41 and a millennium later." It would be the contentious issue of the Imperial date over which the [[Ordo Chronos]] would wage the internal [[Chronostrife]] amongst itself.{{fn|16c}}

[[Aaron Dembski-Bowden]] on his personal Twitter account had this to say regarding the notion of M42:
<gallery heights="350px" widths="300px" mode="nolines">
ADB Twitter Post1.png|Aaron Dembski-Bowden on Twitter
ADB Twitter Post2.jpg|Aaron Dembski-Bowden on Twitter
</gallery>

Certain battles that have confirmedly taken place post Great Rift, such as the 2025 [[Grand Narrative]] battle for [[Mordian]], which would include forces of the resurgent [[Leagues of Votann]] and also of [[Primaris Marines]], are described by Games Workshop as "in the 41st Millennium."{{Fn|52}} In the 2017 version of [[Dark Imperium (Novel)]], the time period was explicitly described as the 41st Millennium, though this would be changed to "Era Indomitus" in the second edition of the novel.{{Fn|41}}

For the purposes of convenience, in order to create some semblance of chronological event ordering and not to confuse certain events with others that have confirmedly occurred early in [[M41]] and well before the [[13th Black Crusade]], '''M42''' is used by Lexicanum for certain dates. Some of these dates, as mentioned previously, have themselves been stated by Games Workshop as occurring in M42. Others are conjectured extrapolations based upon the notion of setting the events of the [[13th Black Crusade]] in 999.M41 as stated by [[Games Workshop]].
