Imperium of Man - Age of Technology, M15-M25: The first indications of Human Warp travel date from the early millennia of this age, in ca. M15. They hint at gruesome disasters and many setbacks, yet it is clear that eventually the faster-than-light Warp-Drive technology was perfected. The cultivation of the Navigator gene -- and the establishment of the Navigator Houses -- came soon after, allowing vast leaps in interstellar travel and the establishment of a full-blown Human empire amongst the stars.As Humanity's power and influence grew, so too did its hubris. The indomitable spirit of Human endeavour has ever riser to the sternest challenges; interstellar exploration, trade and -- inevitably -- warfare presented challenges like nothing Mankind had faced before. Planetary colonisation proceeded at a ferocious rate.It seems likely that, during this era, the Human race splintered and reformed time and again into warring or competing power blocs and planetary empires, but nothing could destabilise Human space as a whole.Human scientists, engineers, inventors and innovators became the new gods. They worked alien technologies into their species' devices to increase their efficacy with little thought to the risks. They modified their species' genome to ever greater degrees, fashioning vast armies of tailored gene-troopers whose Humanity was all but lost amidst the array of freakish alterations worked upon their bodies and minds.They invented Standard Template Construct machines -- or STCs -- that allowed Human colonists to rapidly fashion everything they needed to dominate new worlds from whatever natural resources were available. They developed sentient nano-plagues, world-sundering directed energy weapons and endless ranks of fearsome artificially intelligent Men of Iron that could be unleashed upon those who refused to bend to their wills, alien and Human alike. They fashioned thinking machines of vast intellect that administered to the every need of colony worlds transformed into glittering utopian paradises.It was during this age, also, that Humanity's psychic evolution is said to have accelerated apace and therein lay the seeds of this first Humanempire's annihilation. Arch-historitors, chronopedants and Inquisitors of the Ordo Hereticus have combed what scraps of information exist from this era and have agreed upon two things; first, that it is impossible now to separate fact from fiction, and second, that the first mentionsof Human psykers appear around the end of M22, are near ubiquitous across Humanity's worlds by late M23, and that absolute anarchy is said to have engulfed the worlds of Mankind soon after.The collapse was sudden and appalling, a wave of apocalyptic catastrophe that swept across Human space. Terrible wars saw entire star systems scoured of life. Armies of mechanical soldiers marched against their creators and slaughtered billions. The scourge of mutation ran rampant and everywhere psychic atrocities were unleashed, everything from psykers claiming godhood over entire worlds to daemonic possession and full-blown reality collapse as the Warp breached the dimensional barrier and invaded realspace.Then came the most ferocious Warp Storms that had been seen in all of Mankind's history, cutting off all interstellar travel, trade and communication. Collapse followed swftly.
