The Battle of Castobel
The Crusade of the Red Redemption
The Crusade of the Red Redemption (or as they are more commonly called, the Redemptionists) is one of the most notorious of these extreme religious sects that often form the Frateris Militia. Their creed is one of violence, paranoia and xenophobia, as they see all humans as inherent sinners against the Emperor, unless proven otherwise. As a militant sect, they frequently gather to fight Wars of Faith in the name of the Emperor, whether the Ecclesiarchy desires these conflicts or not.
The Redemptionists have a succesful hold on every Hive World in the Sector, with the firebrands of the sect often travelling to the lower hives to scour them of the unclean mutants.
