Chaos - Those Who Live Within: For those with no love for the Emperor's laws, life inside the Imperium is a daily peril. Within a social system where the innocent are routinely persecuted, the guilty must stay especially on their guard if they hope to survive. For most citizens the Imperium is nothing but a source of oppression and fear, and not all of those that cry out against the yoke of its authority are the dedicated servants of Chaos.The religious intolerance of the Ecclesiarchy persecutes entire belief systems by branding them as heresy and daemon worship for the slightest deviation from the dogmatic and orthodox Imperial Creed. Psykers and mutants face a terrible fate at the hands of the Imperium, at best existing as a shunned underclass in those rare places where they are not executed on sight.Political parties, labour movements, guilds and even criminal organisations that were once vilified by the citizenry can sometimes become their outlet for anti-Imperial sentiment when the authorities tighten their grip.Fear of the Inquisition quickly drives these diverse groups underground to form a hidden network of cells and covens dedicated to the downfall of Imperial rule. Secret cults of worshippers tend shrines dedicated to their ancient gods in secret while presenting a face of bland devotion to the God-Emperor in public.Humble workers toil in the factories while they plan revolution and the overthrow of their hated bosses. Wherever there is sedition and dissent the conditions become ideal for the subtle spread of Chaos.The lure of arcane lore and unearthly power exercises a fatal attraction for the ambitious and the desperate. All over the galaxy, even on Mars and ancient Terra, there are people willing to dabble in matters beyond their understanding in the pursuit of power or forbidden knowledge that will set them apart or above their peers.Not all of these realise they are dealing with the Powers of Chaos, innocently becoming involved through warrior societies or intellectual communities that may appear outwardly quite benign in nature.Often a Chaos Power is venerated under a different guise with a seemingly unconnected name, and a host of Daemon Princes and Lesser Powers are worshipped by different cults with just as much fervour as those dedicated to the Great Powers of Khorne, Tzeentch, Nurgle, or Slaanesh.Some cultures devote themselves to Chaos in its unaligned glory and see the Powers of Chaos as a pantheon of gods, a polytheistic outlook common in many tribal religions.Ecclesiarchy missionaries usually try to insert the God-Emperor into such belief systems, claiming Him to be more powerful than the others, but change is slow to occur and the last vestiges of Daemon-worship are notoriously hard to stamp out.Even pious-seeming monks and holy men may transpire to be followers of "saints" who possess, upon closer inspection, decidedly daemonic aspects.Those who truly desire change sometimes go to the most extreme lengths to gain the power they need to affect it. Forbidden lore, suppressed knowledge, and ancient pacts may offer routes to victory for an ardent freedom fighter or revolutionary where weapons and bombs fail to make an impact.On some worlds, the spread of law and industry rouses anarchists and madmen to oppose it, on others gentrified nobility anxious to keep control of their lands might turn to the methods their forefathers used in earlier, darker ages.Even the most advanced and powerful Imperial worlds have their own secret cults that have hidden themselves from sight for centuries while their members work tirelessly to worm themselves into position of power and authority. Such cults are a source of great concern to the Inquisition, none more so than those that actually manage to communicate with daemons directly or -- worse still -- summon them from the Warp.
