Silver Age Beyond
The new universe of Postuman Space was made up of fractured, planetary nations, ruled by the children of all-powerful ancient parahumans, steeped in mysticism, drunk on their inherited technological might and seething with hubris at their god-lineages. Some worlds were democratic, some totalitarian. Many of the original rulers of these worlds created dynasties which would last for millennia: the first noble houses to rule the stars. But years of political and social experiments yielded only chaos and strife between worlds. Into this dangerous universe came the Prophet, a man with a vision of Creation he claimed was gifted to him by God, whom he called the All-Maker. The Prophet gathered disciples and followers about him and performed many miracles. A humanity desperate for unity and hope looked to the Prophet for their answers.
During this time, posthumanity met its first sentient race, the ungulate Tauslons. At first, they were thought to be merely clever rhinolike beings. But it was soon realized how intelligent they were — and how dangerous. Another sentient race, the Stoucrix, were gifted with psychic powers — powers which they used to goad the Tauslons into a bloody revolt. By the time the truth behind the Tauslons’s rage was discovered, it was too late to reform the beasts in posthumanity’s eyes: the “dangerous and uncontrollable” Tauslons were enslaved and moved to reservations across the Galactic Imperium, breaking up their families and culture.
The following Stoucrix War united humanity against an-other star-faring race, one inimical to human interests. With the aid of the Stoucrixi’s cousin race, the Reikaw, posthumanity gained ground in their galactic war. Finally, a follower of the Prophet, led the newly formed Universal Sectus of the All-Maker against the Stoucrix on their homeworld. Posthumanity was victorious, and the place of the Sectus in future politics and martial power was cemented.
Posthumanity marched across new worlds and subjugated the sentients living upon them, most of whom were incapable of star travel and thus considered inferior.
Until the Jith. Post-humanity met more than its match when it subjugated a peaceful race of gardeners known as the Hoylachi. When their overlords arrived from unknown worlds in vastly superior starships with devastating energy weapons, humans had no choice but to fall back and go no further. Luckily, the Jith were non-expansionistic, and pursued no vendetta against posthumanity. As long as they were left alone, they would cause no trouble — or so most posthumans believed. But enigmatic “gifts” and lore from the Jith over the centuries have been curiously effective at starting conflicts among posthumans.
With the close of the Diaspora, posthumanity entered into the golden age of the Second Republic.
