The Neoaster Period
The Pre-Space Age

12,000 (10,000 BC) years ago to 1945 AD


10,000 BC (12,000 years ago)

  • As the great continental ice sheets melt, coastal flooding increases.  The Bering Land Bridge, linking Eurasia and North America, is inundated and lost.  At the same rough time period, the megafaunal extinction begins to hit world wide.  Species such as mammoth, ground sloths, and other major animal groups vanish.
  • Some of the earliest settlements in what will become known as Jericho are established.  These are seasonal camps settled by the survivors of the Lost Civilization.  Already fallen to a much more primitive level than their ancestors, they have nonetheless maintained a small level of technology, although this is fading swiftly.  They are more beholden on what they can make a living from in the natural world, rather than what the old Sivata technology can provide for them.
9700 BC (11,700 years ago):  The Younger Dryas comes to an abrupt end.  In less than a decade, the average temperature of the Earth rises by some 7 degrees.  In North America, a blatant indication of this is the refilling of Lake Agassiz, reformed once more by melt from the swiftly retreating continental ice sheets.
9600 BC (11,600 years ago):  Permanent populations now inhabit the region that will become home to Jericho.  These people are largely descended from those of the Lost Civilization, but have begun to lose their identity.  Permanent residence in this region is precluded on stable agriculture, and the influx of native Human peoples from the surrounding regions.  While other Lost Civilization centers maintain their cultural identity, most notably that of Doggerland, these people have truly begun to "go native".
9564 BC (11,564 years ago):  The fall of the last centralized Lost Civilization government, which is located in Doggerland.  Up to this point, the polity had survived by maintaining the last dredges of ancient Sivata technology.  But even this high order equipment had finite life times, and in the end as it slowly succumbed to age, so did the Lost Civilization slide into a more technologically primitive order.  Lost civilizations around the world become isolated and insular, sliding even further into primitive states.
9000 BC (11,000 years ago):  The earliest beginnings of the Göbekli Tepe site in what will become the Anatolia region of Turkey is established.  Once a Lost Civilization outpost and global communications center, the native peoples of the region have moved in on what was, to them, a sacred site.  At this point, there are no permanent residents.

8000 BC (10,000 years ago)

  • Doggerland is a land of lush woodlands, lakes, and a rich biodiversity.  It remains as a center of high order civilization, albeit one that has long since lost all ties with their technological past.  Nevertheless, being a center of stability, and being located in such a lush land, it serves to draw other populations to it.  This native influx has long since been eroding the Lost Civilization cultural hallmarks and replacing them with those of the emigrating peoples.  Indeed, Doggerland has become a sort of Neolithic "Atlantis".
  • In Jericho, permanent settlers have begun to build the first walls of the region.  While in reality they are meant to aid in flood control, it is a demonstration of technological prowess unseen by most other peoples of the region.
  • In Mesopotamia, some of the first post ice age agriculture  by native peoples has begun to flourish.  It is the beginnings of classical Earth civilization.
7800 BC (9,800 years ago):  The collapse of the Yana'cree civilization on Mars.  Overcome by a strict religious system and, later, rebellion and civil war, the entire culture fragments into a series of nomadic clans and chiefdoms is less than two generations.  As the centuries wear on, the people would split and disperse even further, becoming nothing more than tribes of hunter-gatherers.
7500 BC (9,500 years ago):  The Neolithic Subpluvial begins in North Africa.  This latest of temperate trends turns the Sahara green once more, and a rich ecological system is established.  Humans swiftly migrate into this region, including the last of the nearly true blood descendents of the Lost Civilization.  Migrating from the shores of the Mediterranean, these people establish a theocratic society that is intent on bringing a return of the ancient gods, what the people remember as the technologically advanced Sivata.  However, the society will swiftly fall into the rule of a series of leaders who have claimed to have been chosen by those gods, and who in fact set themselves up as a line of god-kings.
7000 BC (9,000 years ago):  A tidal embayment forms between England and Doggerland as sea levels continue to rise, cutting England off from the mainland for the first time since the Eemian. The population of Doggerland plummets as travel between these two fertile regions is cut off, and the cultural sophistication of the relic culture here also begins to fracture.
6500 BC (8,500 years ago):  Continuously rising sea levels caused by melting glaciers and remnant ice sheets have reduced Doggerland to a series of low islands.  The largest of these islands is Dogger Bank, a hilly area and the highest portion of the ancient Doggerland landmass.  These islands still support rich biomes, however, and they are still inhabited by Humans descended from mainland peoples and the Lost Civilization.  However, these reduced landmasses mean reduced resources, and those peoples that do remain living on these islands have become hunter-gatherers.
6200 BC (8,200 years ago):  Lake Agassiz suffers a breach in its ice dam and catastrophically drains into the ancestral Hudson Bay, and from there the oceans, raising world oceanic levels by some 9.2 feet over the next several years.  This drainage has a major impact on the Doggerland islands, eroding the lands away into an even more low lying archipelago.  Human populations bottom out on the islands during this period as most of the people flee towards either mainland Europe or Britain.
6150 BC (8,150 years ago):  The Storegga Slide, an underwater landslide of epic proportions, strikes off of the coast of Norway.  A 16 foot tsunami is generated that devastated coastal regions throughout the North Sea region, as well as washing over the Doggerland Islands.  The remaining Human populations of these islands are wiped out, and the islands themselves are stripped of almost all vegetation.  Several of the smaller remaining islands are washed away entirely.  It is the end to the line of the Lost Civilization in this region.
5600 BC:  The Mediterranean Sea breaches a sill in the Bosporus Strait.  The result is the sudden flooding of the up until then fresh water Black Sea.  For some 300 days the flooding continues, until the Black Sea is at its modern levels.  Several major farming communities and cultural centers are displaced, and as a result agriculture is forced westward into mainland Europe.

5000 BC

  • The last remnants of the Doggerland islands sink beneath the rising, turbulent waters of the North Sea.
  • As agriculture begins to take hold of the populations in Europe, the people begin to develop light colored skins.  Vitamin D is lacking in agricultural foods, and the move to lighter skin is an adaptation which aids in absorbing vitamin D from sunlight.

3900 BC:  It is the end of the Neolithic Subpluvial, and the desertification of northern Africa.  Also known as the 5.9 Kiloyear Event, this climatic change brought about the migrations of Humans into river valleys throughout the world, in search for more fertile and prosperous lands.  In Africa, the Nile River Valley saw a major influx as well, an event which lead directly to the beginning of the first "modern" complex state-level societies.

Perhaps the most notable disruption caused by this climatic event was the final downfall of the ancient line of god-kings.  Long since fallen into complete decadence, memories of their origins lost to twisted myths and legends, their rule had been twisted and turned harsher, more cruel, and had reached a malevolent high as environmental conditions worsened.  In the end revolt by a frightened and angry people brought them down, shortly before the exodus from their swiftly desiccating land.  Left behind was a single member of the god-kings, a singular example of the most pure blooded Sivata left on the planet, surrounded by a small core of believers.  In only a few years, their hidden compound would be buried by the encroaching sands, and utterly forgotten by the world around them.


3100 BC:  The beginning of the early Dynastic Period of ancient Egypt.  All the common hallmarks of Ancient Egypt form during this period.

2600 BC:  The height of the Indus Valley Civilization.  Over five million people inhabit the region and are known for their urban planning, elaborate drainage systems, and extensive water supply systems.

1610 AD:  The first crude telescopic observations of Mars are made by Galileo Galilei.  While he could not see any surface detail using this earliest form of the telescope, he was able to observe and make not e of seasonal color variations, ranging from a rich summertime blue to a distinct yellow winter phase.  On occasion he observed a deeper red color shift, noted from antiquity, which corresponded to the planet's occasional world-wide sandstorms.
1877 AD:  The first astronomical maps of Mars are made, based off of long hours of observations through crude telescopes.  While the maps do portray relatively accurate coastlines and even some major river systems, the Angry Planet's dust storms as well as normal weather patterns serve to introduce false features, many of which are placed on the maps and will survive as "real" features for decades.  The presence of oceans and rivers, however, ignite a fervor of "life on Mars" speculation.
1902 AD:  Some of the first maps of Venus are made via telescopic observation.  However, because of Venus' dynamic atmosphere, different maps often portray different  continental configurations.  While many maps touch on the reality of Venusian topography, none come close to it.  Regardless, these observations introduce the concept of "Earth's Twin Sister" into popular culture, with speculations ranging far and wide on the nature of possible life on the planet.

1945 AD

July 16:  The Trinity Test, in which the first atomic weapon is test detonated.  World War II is abruptly ended, and the nuclear age is begun.
