Olamic Quietude

The Olamic Quietude was a hostile post-human civilization that the 40th Expedition Fleet and the Space Wolves Third Company encountered during the Great Crusade. From first contact, they considered the Imperium of Man a mockery of humanity. The Quietude considered itself the rightful successors to Terra and saw Imperials as xenos-infected impostors. As a result, the Quietude captured and vivisected the first Imperial emissaries, resulting in war between the two civilizations.
