Radicals are a political and philosophical faction of the Inquisition. Setting themselves apart from the more conservative Puritans, the pragmatic Radical Inquisitors follow the Imperial doctrines in spirit, believing that the ends justify the means, and find little value in adhering to convention too closely. They often try to fight fire with fire, using Chaos or xenos weaponry, employing Daemonhosts, or committing other acts that would be deemed heretical by their more conservative brethren. Their experimentation with these forces often leads to them being branded heretics, or succumbing to the very power they sought to control.
