Hi All this has been superseded now. But keeping up for records. Please search for Timeline updated post Tempest on our search bar. http://battlebunnies.blogspot.co.uk/2015/05/great-crusade-timeline-updated-with.html

Attention Timeline Junkies. 

I have spent a few days piecing together a Timeline starting in the Great Crusade, going through to early Heresy. 

It follows the OFFICIAL Primarch discovery order from Black Library which is tied to known Primarch discovery years. Estimated (est) ones are where I have "fit" them based on their order and an equal spacing between 2 known Primarch discoveries years. 

Shows some interesting bits. 

M30 800 - Emperor launches Great Crusade

M30 802 - Horus is discovered a couple of years into the Great Crusade and is mentored for 3 decades before the next Primarch is discovered.

M30 832 - Leman Russ is discovered 30 years after Horus. 

Between M30 833 and 844 Missing Primarch A is discovered (est 835), then Ferrus Manus (est 840). 

M30 844 - Fulgrim is discovered. 160 years before Horus Heresy (age of his flagship). 

Between M30 844 and M30 854 - Vulkan (est 846), Rogal Dorn (est 848), Roboute Guilliman (est 849), Magnus the Red (est 850), Sanguinius (est 852), Lion El'Jonson (est 853) are discovered. 

M30 854 - Perturabo discovered.

Now there are a few of inconsistencies, be it Primarchs mentioning that other Primarchs were around when they were discovered and feel free to mention below. If I have anything drastically wrong in your opinion let me know, but site which book, chapter, page even that it is mentioned. Try to keep the "If I recall"'s to a minimum. 

Such as:
In the novel Deliverance Lost, in Corax's reflection on his first meeting with with the Emperor, the Emperor mentions that there are seventeen other Primarchs. When Corax asks how this can be possible, as he is the nineteenth, the Emperor's face becomes "bleak, filled with deep sorrow", and he says that it is "... a conversation for another day." This indicates that the II and XI Legions were already lost, and possibly expunged, by the time that Corax was reunited with the Emperor. It also suggests that they were lost in the earlier years of the Crusade, as the Emperor mentions that most of the other Primarchs had already been discovered by the time that he came to Lycaeus.

This does say he is the eighteenth recorded technically (there are 17 others). That would lead to the II Legion and XX Legion after.

I would be happier if the missing Primarchs were written off earlier in Great Crusade too.
