The 28th Expedition Fleet was commanded by Fulgrim.
The Commander of the Archite Palatines was Thaddeus Fayle. He was a stern man with a horribly scarred face, augmented with a steel plate that obscured the side of his head. He was a skilled general, a blunt speaker and a ruthless, unforgiving soldier.
Presumably during the heresy the Palatines remained aligned with the Emperor's Children, eventually morphing with their remembrancers into their supporting masses of unaugmented human worshippers of Slaanesh.
