Early Neptunian Subhuman Epoch

The Early Neptunian Subhuman Epoch was the long opening phase of humanity’s Neptunian history, defined by the collapse of the Ninth Men and the survival of their descendants as animals. The period makes a severe distinction between designing a species for a world and actually surviving there: the colonists’ makers had planned a diminished copy of themselves, while Neptune demanded hardier life. In the first six hundred million years of the Neptunian sojourn, human form and civilization largely vanished; only much later did human consciousness begin to reawaken.

Chronology and Setting

The Ninth Men were created in haste by the last human inhabitants of Venus to colonize Neptune. The planet’s remoteness had prevented thorough exploration, and the new species was only partially adapted to its destination. Their designers made them small enough to withstand excessive gravity, but cramped their brains to the bare essentials of humanity. Rather than produce a tough, prolific, physically robust pioneer, they fashioned a miniature version of their own delicate type, suited to a stable civilization that the new world could not sustain.

Neptune’s physical conditions turned that design error into a prolonged crisis. The planet was entering a phase of crustal shrinkage, bringing earthquakes and eruptions. The colonists faced sudden fiery fissures, volcanic dust, lava, unstable building foundations, and a massive, turbulent atmosphere capable of destroying their structures. Its unhealthy composition further undermined the cheerfulness and courage of a population already prone to neurosis. The Ninth Men’s civilization could not withstand these combined pressures.

Collapse and Animal Survival

The collapse was gradual rather than a single recovery or decisive turning point. As civilization crumbled into savagery, the painful awareness of better ways of life faded; consciousness narrowed and coarsened into what the account describes as brute-consciousness. The brute descendants survived where the civilized Ninth Men had failed. This survival did not restore human society: for a long period, the line persisted as living organisms without a recognizably human mode of existence.

The wider history places most definitely subhuman, degenerate forms within the first six hundred million years on Neptune. During the earlier half of that preparatory span, humanity was nearly extinguished by its hostile environment and gradually spread through the great northern regions, but as beasts rather than as people. The later half brought a gradual awakening of human spirit, followed by the fluctuating advances and retreats familiar from earlier ages. The epoch therefore belongs to a much larger transition: it records not simply a decline, but the long interval in which biological survival preceded the return of human consciousness.

Diversification Across Neptune

Nature, slowly and without a guiding plan, achieved what the Ninth Men’s designers had not: descendants adapted to the varied environments of Neptune’s lands and seas. At about two hundred million terrestrial years after the solar collision, the polar continent supported numerous subhuman grazers, while smaller carnivores hunted them or fed on other animals and carrion. Some of the ancient Venusian fauna had also reached Neptune, including insects and other invertebrates; microorganisms and accidentally transported vermin helped establish additional forms of life. Plants bred for the new world ultimately gave rise to grasses, flowering plants, thick-trunked bushes, and unfamiliar seaweeds.

The marine environment produced its own branches. Marine worms became, in time, vertebrate and predatory, with swift, fish-like forms. Descendants of humanity entered the seas as subhuman seals and more specialized porpoises. On land, a small insect-eating, bat-like glider gave rise to varied flying mammals, some agile in flight and no larger than hummingbirds. These divergent forms show how thoroughly the inherited human stock could be reshaped by different ecological niches: the epoch’s descendants were not one degraded animal type, but a multitude of forms adapted to separate ways of life.

Ancestral Traces and Historical Significance

The typical human form did not survive in this world of animal descendants. Yet vestiges of human mentality and anatomy remained. Forelimbs retained buried remnants of the once dexterous fingers. Some grazers gathered during hardship and answered a leader’s calls with a collective chorus; some carnivores intermittently withdrew to a high place and remained there, watching, until hunger brought them back to ordinary activity. Such behaviors are presented as surviving traces, not as the return of human society or fully restored human understanding.

Neptune’s immense seasonal rhythm shaped the pace of this history. Its year lasted about one hundred and sixty-five times as long as the former terrestrial year. Most organisms therefore lived through at least one complete Neptunian year, and higher mammals lived longer still. This natural longevity would later assist humanity’s revival, but slow individual growth and prolonged immaturity also retarded evolutionary change. Compared with the Terrestrial and Venerian ages, biological history on Neptune consequently advanced at a markedly slower pace. The epoch’s central contrast lies in that double effect: the same world that made adaptation and development sluggish also preserved life long enough for a later resurgence to remain possible.
