Editing Unnumbered Sons (section)

==Origins of the Unnumbered Sons==

After Archmagos Dominus [[Belisarius Cawl]] unveiled his 10,000 year project to Guilliman, the Imperium had thousands of these new Primaris Marines ready and available for use. The beginning of the Indomitus Crusade and the Ultima Founding meant that this massive force would have to be used on the battlefield as soon as possible. Thus, the Unnumbered Sons, famous for not wearing any chapter heraldry (having nothing drawn on their pauldrons and nor any colour on their armor, hence the nickname "greyshields" (it seems Cawl ran out of Citadel Paints and was forced to run a Grey Tide), were forced to push the tides of Chaos back and stop the [[13th Black Crusade]]. During the duration of the conflict, Guilliman used this chapter to draw reinforcements and new chapters, reinforcing under-strength chapters with new blood and establishing entire primarine chapters. This, combined with the losses caused by attrition, meant that the Greyshields' numbers began to shrink fast.

By the time Roboute Guilliman declared the end of the [[Retcon|first phase of the]] crusade, around 20,000 Greyshields still existed. After the Battle of Raukos was over, Guilliman (having declared the Indomitus Crusade over and his intent to fight [[Mortarion]] in the [[Plague Wars]]) ordered the disbandment of the Unnumbered Sons, to either add them to already existing chapters who had yet to receive reinforcements or to create more new Astartes Chapters from the final core of veterans to cap off the Ultima Founding; formally rendering them defunct.
