Localized wars and disputes with various alien races, notably the Orks, erupt but these pose no threat to the overall stability of human-colonized worlds. Then two things happen almost simultaneously. First, humans with psychic powers begin to appear on almost every colonized world. Second, civilization starts to disintegrate under the stress of widespread insanity, daemonic possession, and internecine strife between these new psykers and the rest of humanity. Countless fanatical cults and organizations spring up to persecute the psykers as witches, and/or degenerate mutants. At this time, the existence of the creatures of the warp, later known and feared as daemons, and the dangers they pose to the human mind with newly awakened psychic powers, is far from understood. Terrible wars tear human civilization apart. Localized empires and factions fight amongst themselves as well as against fleets of Orks, Eldar, and other aliens whose forces are quick to seize the opportunity to sack human space. Many worlds fall prey to the dominance of Warp Creatures whilst others revert to barbarism. Humans survive only on those worlds where psykers are suppressed or controlled. During this time, Terra is cut off from the rest of humanity by terrible warp storms, which cause starvation and strife in a society that had grown accustomed to imports for sustenance.
