Changes

*{{Endn|Note 1}}: "unmarked": The [[Ultramarines ]] who served at in the [[Battle of Calth ]] received, both physically as well as psychologically, the [[Mark of Calth]]. They were changed, and from then, differed from their brothers who had not been present. The latter were thus called the "unmarked", and were never again able to fully fit in with the rest of the legion [[Space Marine Legion|Legion]] that had endured the horrors of Calth. Even [[Roboute Guilliman ]] appeared uncomfortable in their presence, as they reminded him of what his legion had lost at Calth. In the [[Great Scouring]], the "unmarked" chapters were increasingly deployed away from the remaining legion, and they were among the first to be split off and organized into independent Space Marine Chapters [[Chapter]]s during the [[Second Founding]].{{Fn|1g}}
