{{Main|Ultima Founding}}

Cawl's Primaris Marines are used to reinforce a number of Marine Chapters to get them back into optimal fighting strength while some new Chapters composed entirely of Primaris Marines are also founded.

While the majority of Chapters have welcomed or at least accepted the reinforcements, there is still a considerable deal of distrust among Chapters who are wary of the newcomers, as well as those who fear that the "Firstborn" Space Marines may ultimately be replaced. For now at least, these concerns have been left on the back burner in favor of dealing with more immediate problems.
