Pentarchy of Blood
The Pentarchy of Blood was a gathering of five Chapters of the Adeptus Astartes that were convened by the High Lords of Terra in 860.M33, during the War of the False Primarch. They were tasked with destroying eleven Chapters judged Traitoris Perdita for their actions during the war, and systematically destroyed the traitorous Chapters and laid waste to their Homeworlds, finally bringing an end to the eight decade conflict.[1]
