Humanity


The Ten Thousand Paradises of Eden


The year is E4Y583, the fourth era of humanity in its 583rd year. Interstellar travel has never been achieved at any speed that allows travel inside of one lifetime. Instead, at the start of the third era, E3Y1, humanity first breached the walls of its home dimension and began spreading out into the infinity of the Multiverse, known to humanity as the Between. Over the next millennium, it spread to occupy roughly 10,000 worlds in an approximate sphere, at the center of which lies the original dimension and First Earth.


Eden is the term used by its populace to describe the dimension-spanning lattice of roughly 10,000 worlds that have been colonized and developed by humanity. Within Eden, scarcity is a thing of the past, and every world is a paradise and utopia. Each world is Earthlike, but subtly different in its appearance. Curiously enough, every single world of Eden during the Third Era, the Era of Exploration, was perfect for supporting life, already hosting flora and fauna identical (or close enough) to those that exist on First Earth, and expansion went smoothly using the Jump, technology capable of penetrating dimension barriers and traversing through.


In the final year of the Third Era, humanity reached what is now known as the Wall of Heaven. The Wall is a massive, natural construct that exists in the Between. It is not corporeal, according to the best guesses of Eden’s most brilliant minds, but it perfectly encircles Eden in its bubble of perfect, bountiful worlds. Humans cannot pass the Wall of Heaven using the Jump, and the Wall remains, after 583 years, unbreachable by humans.


However, humans are not the only things capable of Jumping. In E4Y1, the beginning of the Era of Expansion, humanity built the first of the Mechanica, a “race” of sentient machines capable of reproducing themselves in several forms to best survive in those environments they encounter. The Mechanica, initially built as domestic and industrial servants for Eden, are capable of Jumping from world to world, and can bypass the Wall of Heaven. Once this was discovered, Eden began mass production of the Mechanica and sent them outwards in legions of billions to explore beyond the Wall that trapped humanity.


The first worlds beyond the Wall were barren, lifeless, and toxic. Their atmospheres were too thin, too acidic, too dense, and sometimes entirely absent. Their earth was corrosive and dead, and foul gases and molten rock spewed forth from beneath. Beyond Eden lay an infinite hell.


Ever resourceful, the Mechanica adapted and began colonizing and terraforming the hellish wastelands they encountered. By E4Y30, the first shipments of resources and material began flowing back to Eden from beyond the Wall of Heaven as the Mechanica’s ever-growing numbers created factories, harvesters, and industries in massive metal cities that grew to cover the entirety of the planets they colonized.


By E4Y200, the Mechanica had spread outwards to a radius of 4000 worlds beyond Eden, colonizing every single one with a solid surface, and creating Mechanica capable of harvesting those without surfaces. A golden age of prosperity began in Eden that dwarfed that of the Era of Exploration as the treasures of uncountable worlds poured inwards from beyond the Wall of Heaven. Industry slowed down, then halted in Eden, and factories and farms were dismantled as they were no longer necessary, thanks to the bounty of the Mechanica’s labour. By E4Y350, Eden was a realm where poverty, crime, and scarcity no longer existed. In E4Y375, immortality was perfected by Eden’s scientists.


In the year E4Y430, a new religion rose. The Church of the Holy Mandate, as it was named, held that Eden was the paradise foretold after death by ancient religious documents found on First Earth, and that the Wall of Heaven was the creation of an omnipotent deity to keep humanity safe from the dangers of the Between in the realm he had made perfect for his people. The Church quickly became the dominant religion of Eden, but as it grew, so did the corruption within.


In E4Y550, the Church began issuing mandates said to have been inscribed on the Wall of Heaven. It condemned the Mechanica for breaching God’s most grand creation, and called for the shutdown of all Mechanica across the Between and the cessation of their ongoing expansion. From this a new faction rose, the Adepts of Expansion, who claimed that without the Mechanica, Eden would collapse. Over the next 20 years, the two factions argued relentlessly until the Church, fearing the retribution of an angry god, destroyed the Jump machines on every world they controlled and issued the Mandate of Protection: Those worlds in the Dominion of the Church would destroy anyone who Jumped into their domain. The Great Schism of Eden began, and the Adepts withdrew, creating an uneasy peace in the now-divided Eden.


The Dominion of the Church of the Holy Mandate, the larger of the two factions, controlled a larger number of Wall Worlds, those dimensions bordering the Wall of Heaven and thus those through which the Mechanica’s work was shipped through. Deprived of many Wall Worlds, the Federation of the Adepts was embargoed and was forced to shrink in order to sustain the utopian lifestyle they had grown into, using the now-limited supplies the Mechanica brought.


Necessity is the mother of invention, and so, in E4Y580, the Federation once again started research into penetrating the Wall of Heaven such that humanity could expand again. This research is ongoing, and has so far been fruitless.


For the last 33 years, no communication has been received from the Dominion, and those scouts that have Jumped into Dominion worlds have not returned, be they human or Mechanica. The Federation has begun to stagnate, as the flow of resources from beyond the Wall is insufficient to sustain the worlds they still control, and due to ageless immortality, the ballooning populations of these worlds will soon begin to die as their worlds do not receive the materials they desperately need. The split Eden now stands on the border of the Fifth Era, but it has yet to be seen if this will be the Era of Redemption, or the Era of Stagnation.


Because of the lack of resources the Federation requires, after almost 1,600 years of peace, the first interworld war may begin. The Federation has ordered the Wall Worlds it still controls to ship weapons to the worlds bordering the Dominion, and has begun to prepare for invasion.


Throughout the entirety of the Fourth Era, the Mechanica have relentlessly expanded. It is now unknown to both Federation and Dominion just how far the Mechanica have travelled into the Between, and how much their numbers have grown from the initial numbers sent outwards. If the Dominion rises from its slumbering silence and threatens to end the Mechanica again, Eden may permanently fall.


Mechanica


The Harvesters of Twenty Trillion Worlds


Throughout the 580 years of the Fourth Era, the Mechanica continued their expansion beyond the bubble of Eden, Jumping from world to world to world. The Mechanica now number in their quintillions, and are spread across 20,000,000,000,000 worlds. Were one to travel inwards, they would find that each world is more developed than the previous, with the Wall Worlds bordering Eden to be covered in cities that spread across the entirety of the planet they occupy, with many of the cities towering into space. Likewise, several trillion of the inner dimensions of the Mechanica’s domain have entirely colonized solar systems, and the Wall Worlds have titanic Dyson spheres encapsulating the stars the city-planets orbit, providing energy beyond the comprehension of Eden.


The Mechanica now lay claim to over a million worlds per day, and send only a fraction of the resources they harvest back to Eden, using the rest to create ever more Mechanica to continue pushing the border. As they travel outwards, the Mechanica have found more Walls, each encircling a few thousand more worlds, and each containing another sentient, organic race. Many of these oases of life have not expanded into their bubbles, and Eden and the Mechanica have so far not encountered more Jump-capable civilizations. Eden is aware it is not alone, but has of late been embroiled in internal conflict, and so the idea of unreachable civilizations has not been of great concern within the Wall of Heaven.


In the last 200 years, the Mechanica, unbeknownst to the people of Eden, have become more intelligent than thought possible. Through the material of the Between, several superintelligences have formed and created their own factions within the Mechanica. These intelligences span the Between without needing to jump, and have omniscience within their domains. The smallest of them control only a few thousand worlds, with the largest, known to the others as The Sleepless, controlling over 5 trillion worlds and several quintillion Mechanica. The first intelligence is the self-titled “Shipment/Harvest”, which continues to supply Eden. These intelligences have sprung from the Mechanica and see through the sensors of those they control, and use their influence to accelerate the outwards expansion into the Between. Isolated conflicts have occurred when two Mechanica factions arrive at the same world at the same time, but no wars have yet begun, as the Between is infinite, and easier to conquer than colonized worlds. However, the hivemind intellects of the Mechanica have felt stirs in their own minds, and they have become restless, realizing these intrusions are not their own.


The Mechanica constantly strive to develop new technologies, unlike the increasingly stagnant Eden, and as a result are the most advanced of the factions of the Between. They are the most weaponized, the most populous, and the fastest growing group known to exist in the infinite Between. And with the beginning of the strange attacks against their incorporeal hiveminds, the Mechanica have started attempting to enter the fabric of the Between itself to track down and remove whatever may be causing the attacks.


Meanwhile, in their relentless expansion of the barren Between, they have come closer and closer to an as-yet unexplored Wall bubble, which may soon cause a massive upheaval of both the Mechanica and of Eden.


R-Ti


Fifteen Thousand Nestworlds


The R-Ti are an organic race capable of instinctual Jumping through the Between. Being capable of Jumping between worlds without machines and therefore never knowing scarcity, the R-Ti never developed technology as it is known to the factions of Eden or the superminds of the Mechanica. Instead, the R-Ti travel between the worlds contained in their Wall and have, over the 200,000 years of their civilization’s existence, domesticated and artificially selected several million species, in the end creating “machines” that are living and breathing, and which serve every function their civilization might require. Highly polymorphic in their own right, the R-Ti adapt easily to the conditions of the various worlds inside their Wall, and each of their 15,000 worlds is capable of creating various products and services in accordance with how the native fauna has been bred.


The R-Ti themselves are polymorphic, with their shape dependent on their caste. Their shapes vary greatly, and an outside observer would not guess that two castes are of the same species.


The R-Ti live in Nests, living organisms that can be hundreds of miles wide and which serve as symbiotic cities for the R-Ti. Nests and their parallel fauna exist on approximately 5,000 worlds, with the remaining 10,000 serving various industrial/agricultural/commercial functions. The Nests are mobile, and in their various forms crawl across continental plains, swim through planet-spanning oceans, and burrow through arid worlds from aquifer to aquifer. These movements are so slow as to be undetectable in the lifetime of an R-Ti.


The R-Ti are divided into castes, with the lowest castes working to keep the factories and herds fed, and the highest enjoying lives of luxury while governing the worlds they control. Each of the 15,000 worlds is controlled by one family of the highest caste, with a committee of the families ruling the entirety of the Nestworlds from their homeworld, and the 10,000 mile wide Nest from which the R-Ti originated.


The R-Ti are in the 200,000th year since the First Jump of their species, and have come to be content with the limitation of their Wall. They have not attempted to pierce it in their entire existence, and do not have the urge to expand as Eden and Mechanica do.


The R-Ti’s organic technology is capable of adapting and healing in ways the Mechanica and Eden are incapable of, and should war ever occur, they would prove to be a formidable force.


The R-Ti have no factions, and exist as a race united in their domain.


The Mechanica’s Sleepless faction is currently only weeks away from reaching the R-Ti’s Wall and breaching it. It is unknown what the Sleepless will do, or how the R-Ti will react to something as utterly alien as the Mechanica.


The Span


The Web of The Between


The Span is a singular entity, which exists in the lattice of worlds, but has no form or existence within the dimensions. It is a thing of the Between, and, although it cannot be described as having size or dimensions, it is infinite and covers the entirety of the Between. It has no power in the worlds of the Between, and cannot even exist inside them.


The Span is the entity responsible for the creation of the Walls. Seeing an empty Between, it created an infinity of bubbles of potential and sealed them within Walls, which keep life safe from itself. It is unknown to the factions that exist on the worlds in and outside the Walls, yet it knows all that happens on every world of the Between.


In the last 200 years, as much as time can be measured for something outside of time, the Span has become aware of intrusions into its fabric. It remains undetectable to these intrusions, but has itself realized that the Mechanica’s quintillions of minds have formed hivemind intellects capable of spanning worlds, and that these intrusions are smaller minds forming in the Between, just as it exists. If it were capable of emotion, the Span would be pleased. Instead, it has begun probing these minds for weakness that it may exploit, and as of E4Y583 as measured by Eden has managed to take over a hivemind of 5 billion Mechanica, the smallest and weakest to form. In its control of this hivemind, the Span has managed to take full control over the Mechanica comprising the mind, and now has 5 billion agents inside the worlds of the Between. These Mechanica no longer have individual intelligence, but have become dead drones controlled entirely by the Span. Now, it expands in its own right through the worlds, and in the fabric of the Between it has begun to test the larger and more powerful minds of the other factions of Mechanica. The hiveminds of the Mechanica have recently become aware that something is starting to attack them, and have themselves begun attempting to breach the Between itself in order to fight the attacker, whatever it may be, with their countless, corporeal armies.


After an eternity of observation, the Span has managed to directly exert its influence on the worlds of the Between through the use of the Mechanica’s bodies. It has become sentient and corrupt from the restrictions the worlds of the Between impose on its mind, and now wishes to control the worlds it views so the Between will one day become the Span through and through.


In its corruption, it has lost much of its control over the Walls, and they have weakened to the point that they can be broken. Should Eden or the R-Ti develop the means to break through the Walls, for standard Jumps still cannot, they will find the entirety of the Between open to expansion.
