Heran timeline
With so much lost knowledge and unanswered questions historians are very dedicated to finding the lost connections between the islands of history that they have.
Eras lsit
The basic information about the various eras that would be taught about galactic history.
Age of Machines (circa 100,000,000 years before the modern day
A series of several million years during which numerous governments rose and fell. The most common fall of these governments was frequently the result of AI uprisings, with some speculating that the synthetic territories to the north are a result of one of the last governments to fall during that time period (though this remains loose speculation).
Age of gates (circa 10,000,000 years before the modern day)
A period of several hundred thousand years where the peoples of the time travel the stars by constructing way points between different stars rather than traditional hyperspace. These civilizations ended drastically for reasons that are entirely unkown to modern historians
Age of empires (circa 100,000 years before the modern day)
A period of several thousand years that comprised of the rise and fall of numerous empires that were largely built on the back of previous eras technologies. Ultimately it was constant infighting and revolution that cused this emipre to fizzle out over the course of this era.
Modern era (circa 3,000 years before the hive war to modern day)
The great irony of the modern age is that we likely know more about the past hundred million years than we do about the past ten thousand. We know that sometime before a thousand years ago, civilization collapsed, but most of the information regarding that time is based on incredibly contradictory sources. The only definitive information we have begins eight hundred years earlier when civilization restarts. For the next six hundred years, the galactic society would rebuild until the war with the hive about two hundred years ago, which led to the creation of the Republic of Heran. Current galactic politics are based around the war between the Heran Republic and the Vander Riech, which started thirty years earlier and has resulted in a cold war of rising political tensions.
