Speculo is the Latin word for "mirror," and in the context of the fiction createed and developed by User:SArchangel, it may simply refer to the "reflection" part of the complete definition. Speculo, is developing novel-worthy concept of the broad speculative fiction genre including generic elements of science fiction and supernatural fantasy. In its comprehensive narrative, Speculo portrays a profound view on human nature, siding primarily with the classic Judeo-Christian worldview on the issue while maintaining themes that may be presented as critical of philosophical secular humanist views.
Speculo is set in the future and primarily on Earth, although the distance in time relative to our present reality is made unclear. As the world of Speculo is introduced, what is known about this future Solar System is that humanity is no longer the hegemonic species in dominion. Mankind has been locked in a state of instability for about a dozen centuries, since a devastating war with a hostile alien race.
In the near-future from our present reality according to the Speculo timeline, humanity has harnessed an elemental isotope found on its moon, known as "stardust," which is an allusion to the real-life helium-3 isotope that scientists associate with the possibility of 'moon mining.' Stardust can be used to produce massive quanitites of sustainable nuclear energy, effectively replacing fossil fuels with nuclear energy as the primary source of power. Nuclear energy is known to last longer than fossil fuel combustion energy. All other technological advancements in society begin to revolve around this new change. At the climax of advancement, humanity invented arm-sized nuclear reactors, which allow automobiles to run directly on nuclear energy, as well as space travel capable of taking astronauts to as far as the Pluto dwarf planet.
The more detailed backstory is that prior to this state of downfall, humanity was able to develop a long-term energy supply by harvesting helium-3 on the moon, a fuel for nuclear energy production. As the use of nuclear energy became much more common, humanity also expanded its supply options and nuclear power gradually became the modern source of energy and replaced environmentally costly fossil fuels. Eventually the successes and advanced helped humanity prosper and people sought to continue to expand and harvest the rest of the Solar System. Thoughts became actions and humanity ushered a new Space Age, creating an empire across the Solar System.
As the living standards rose significantly, a global evolution of human culture took place. Humanity prided in its utilitarian achievements and called this age a "golden age" or "utopia," off of the Enlightment-era terms. This "utopia" saw the downfall of religious and/or theistic culture in favor of universal secular values by means of generational competition between human philosophies. Slivers of these past cultures remained and they echoed in documented history. People in this fictional future age could be described as much more reckless and "liberal" in comparison to today's modern Western society.
