Ordinary humans are at the bottom of the divine food chain, and second only to small animals in abject vulnerability. They can use only normal physical attacks, a guard which can be broken by the most Basic attack skills, and Basic magic, which they can only cast using the magic stones that are produced by Mediums. The strongest of them are just barely capable of surviving a one-on-one duel with the lowest rank-and-file monsters, and so they must rely on large numbers or Mediums to survive.
Gifted by the Pandora gene, Mediums are humanity's only real hope of defeating the Demon Mother and reclaiming their lost freedom and dominion of the earth. By invoking spiritual beings called Jinn, they are able to use their Resonant Power to manifest their desires as a kind of magic. Their sworn purpose is to bring humanity's most fervent wish to fruition, but no one but their Jinn really knows what they wish for in secret. Mediums live rich and full lives not unlike the nobility of old, and most have only known hardship during their combat training—before they are sent to the surface to die—while the common folk do little more than work. Both classes have mixed feelings about the other's roles, but the birth of a new Medium always brings joy to Agartha, as it means that more jobs will be created, and the city's population will once again be allowed to increase, to support the upbringing of the newest hero.
The so-called "original Medium" who appeared some time after the existence of the Demon Mother was known to mankind. Very little is known about the founder of the Brionac Program; even the name "John Dee" was only ever a pseudonym. Nobody knows why he was so secretive, only a privileged few have ever read the results of his research on the Pandora Gene—and nobody knows why or where he suddenly disappeared to, just as humanity's hope for its future began to rise to new heights.
All humans possess the Pandora gene, but nobody knows what causes the Pandora gene to activate. What is known is that, if it is not active shortly after birth, it is usually too late, and there is no known method to increase its activation rate. In times past, the people of Agartha tried to produce more Mediums by inflating the size of its population, but after some time it became clear that this would not be a viable solution to their plight, and the unofficial communal effort that had gone unacknowledged until then was quietly halted. Now, the population of Agartha is "carefully managed" by its government.
The conduits of power for the Mediums, Jinn are spiritual beings born from human desires. If humans have worshipped something in great numbers, there is probably a Jinn that embodies that thing, be it an object, element, force of nature, or anything else that evokes human desires. Neither inherently good nor inherently evil, Jinn are easily influenced by the human heart. Even when a Jinn is invoked by two Mediums on opposing sides of a battle, it never revokes either its blessing or its curse, even if it will result in the death of a recipient of its contracts. A Jinn is seemingly only bound by these two forces: its contracts, and human desire. Nothing else is known about Jinn. Perhaps there isn't anything to know.
In essence, Resonant Power is created when large numbers of humans believe in something. When a Medium is successful in defeating evil beings and freeing enslaved humans, they gather the faith of their allies and the people. This faith can then be harnessed by invoked Jinn to empower one's body beyond the human limit, or cast magic, creating the phenomenon known as Resonant Power.
Mediums who abandon their duty to fight for humanity's survival are called Mavericks. The loss of the people's faith results in an inability to accumulate Resonant Power. While they are still incredibly powerful compared to regular humans—retaining their ability to use Basic skills and magic—these oath breakers are fodder for Mediums, who are often capable of wiping the floor with a small group of them.
A small, underground civilization with only about fourteen thousand members. Even so, Agartha is rich with resources, and both Mediums and non-Mediums alike enjoy the city's advanced technology and relative safety. A clear blue sky is projected onto the roof of the cave to simulate day time, while the soft blue glow of its flora naturally imitate a beautiful starscape (albeit with the help of a fake projected moon), and a powerful magic/tech barrier repels low-level monsters. Its denizens are ethnically diverse, but most speak only English after living in such a small world for over three centuries. Transportation in Agartha is achieved with inclined elevators and cable cars, as its topography is complex. Life in Agartha is perhaps best described as "perfectly boring." While the Mediums stave off their boredom with unending training and missions, the common folk lose themselves in their work and very limited time for hobbies.
In Agartha, everything revolves around the birth and upbringing of Mediums, as without them, their lives of independence from the demons would be unsustainable. Agartha's population is allowed to increase only when a new Medium arrives, and the vast majority of its resources go into the Brionac Program, which prepares young Mediums for a future mostly spent fighting evil beings. Despite working or training most of the time, the living conditions are downright luxurious compared to those of humans living under demonic rule. Though underground, the cavern is cool, with naturally circulated fresh air.
Food is a constant concern, and is usually purchased not with gold but with meal tickets, which are provided and managed by Agartha's government. Fruit and vegetables are farmed using vertical and indoor agricultural techniques and technology. Large populations of cattle are unsustainable, so most of the meat eaten by its general population is artificially grown in labs, with the exception of fish that can be caught in a river that falls through the cavern. Wild game is costly and almost exclusively reserved for Mediums and their families. Monsters unfortunately yield no meat when killed, as they will degenerate into a kind of sludge, only edible by other monsters, and only used by humans to create magic stones.
While Agartha's technology is advanced, it has regressed considerably in one aspect, and that is communications. Television no longer exists, and the news is spread with a city-wide intercom and old school papers. Landline phones also exist, but all forms of communication over the "air waves," such as cell phones, internet, and radio, have been eliminated, as demons can hijack them to cause mass panic and spy on people. More secure and advanced communication methods are used by Mediums, which run on magic, but have their own limitations. For one, they cease to function entirely during a Calamity.
Like many other governments in the past, Agartha's is divided into legislative, executive, and judicial branches. All members of the legislative congress are human, and are voted in exclusively by humans, while the other two branches are mixed. The executive branch and associated military forces are almost exclusively Mediums, with many humans occupying the lower government worker positions and supporting roles, with few exceptions: Executive Elpidio, for example, is not a Medium, though he occupies a very important position. In short, the Mediums' dependency on humans as a primary source of their power, and the humans' lack of ability to use said power, creates a society where humans must decide how the system will work, while Mediums run it accordingly. The result is surely far from perfect.
Rather than hosting celebrations on holidays regularly throughout the year, Agartha's times of excess are dictated by the death toll. If more Mediums are joining the force, and fewer are dying, a kind of festival colloquially called "Pandemonium" may occur, where many of the city's usual restrictions are temporarily rescinded. Everyone is given some extra time away from work or training, food will become purchasable with gold rather than meal tickets, couples will rendezvous—and all the usual celebratory fare. The noise tends to dissuade monsters from attacking, as the response is usually swift and merciless.
The Brionac Program, and Brionac Academy, are responsible for training Mediums from a young age to combat the demon menace. Mediums are sorted into three different classes, based first on their estimated potential for slaying evil beings, and later based on their estimated body count. First Class Mediums are a menace on the battlefield, while Third Class Mediums are better off in support jobs or staying off the battlefield entirely—at least in theory. Mediums with First Class potential will drop off to lower classes if they don't deploy when Agartha is attacked, or if their body count is low, as will be the case for Valkyries. Drifters are not publicly acknowledged, but are internally referred to as Class Zero.
A full-immersion virtual reality simulator that allows digital versions of evil beings to be fought in a safe environment, with user-controlled battlefield conditions. The program is new, and collecting the necessary data to produce these "Daemons" is difficult, so currently only common monsters and devils can be fought. Its creator, Executive Elpidio, hopes that the newest generation of Mediums can help him change that. He is also known to design his own opponents for aspiring Mediums to fight.
A pitch-black cavern where Mediums who are at least 16 years of age and have graduated from the "education-only" portion of the Brionac Program go to contact and invoke Jinn. Only those Mediums with the nerve to enter this foreboding place alone and emerge successful are inducted into the second portion of the Brionac Program, where it becomes possible to go on missions with one's life on the line. The Void is home only to Jinn, and contains nothing but the metallic remnants of fallen angels. Despite smelling faintly of death, it is completely devoid of any kind of life, including predators. However, due to the sensory deprivation required to contact Jinn, many reportedly experience terrifying hallucinations.
Existing only as fossils, fallen angels are spiritual beings that were forced to assume physical form before being cast out of the heavens. No flesh samples have survived, but a metallic substance was left over, which can be used to make magical weapons and magically infused technological devices. Even normal humans can technically use these weapons after a Medium has infused it with Resonant Power, but whether or not their frail bodies can physically handle the forces generated is another matter.
Medium Job Classes and Occupations
Pioneers are seasoned adventurers who are privileged to choose their own battles, and explore the surface world at their own pace, drawing maps and scouring for what's left of the earth's precious remaining resources. For Pioneers, danger is never more than a hair's breadth away, as demonic cities and forces are everywhere and not always visible without a bird's-eye view. Pioneers must be quick on the draw and on their feet if they want to survive. They stay away from large-scale warfare.
Vanguards are stalwart warriors who defend Agartha from higher-level monsters that won't be repelled by its barrier. They tend to stay within close proximity of Agartha, but aren't afraid to venture out beyond the boundaries of the barrier and confront the hordes of small fry accompanying the juicier targets. Defensive in build, with wide, sweeping attacks, Vanguards are well respected by the people.
Juggernauts are physical powerhouses that live to fight the strongest beings the Demon Mother has on offer. They shine brightest when fighting a single opponent, but are more than capable of taking on smaller groups of moderate-to-highly dangerous monsters, such as a pack of dire wolves. They vary in their preference between speed and defense, but all of them are a force to be reckoned with.
Valkyries are magical specialists with a knack for Resonance. The backbone of any task force, big or small, their supportive abilities are adored by the people, and are always the favorite of young and impressionable girls. However, not all Valkyries are of the emblematic "healing angels" variety. Some specialize in other types of magic, such as blessing's opposite, curse magic. Debilitating enemies in large numbers, they allow even normal humans to get in on the monster-slaying action from time to time.
Warlocks are another type of magical specialist with a talent for laying waste to large swaths of demon scum using your basic elemental magics such as fire and ice, lightning and water, wind and earth, light and dark, etc. You can't go wrong with the classics, and the Warlock has remained effective for as long as Mediums who love magic have honed their craft, which is also as long as Mediums have existed.
Sorcerers are strategic masterminds who specialize in dealing with magical foes. Essentially the "team leaders" of Warlocks and Valkyries, they are tacticians who directly counter the demon army's efforts to thwart the humans' advance with magic, while they themselves handle the "trickier" elements of magic, such as nature and artifice, sight and sound, time and space, and generally abstract spells.
Bastioners are experts in artifice magic who act as architects, either in the city of Agartha or on the surface, quickly building forward operating bases, or FOBs. They can assemble towers and bunkers in no time, even in the middle of a battle, if there's enough space and they're left alone. At higher tiers of magic, they can conjure up rows of cannons or other siege weapons, laying waste to the evil hordes. Both on the battlefield and off, their unique abilities inspire awe and jealousy in the hearts of DIY guys.
A secret job title given to a Medium with unique talents and the motivation to use them to defend Agartha, even at the behest of their life, is the Drifter. Drifters are given freedom to pursue their own targets and to execute their own missions because at any given point in time a Drifter can be called to action in Agartha. A Drifter preemptively hunts down and fells the deadliest of all evil beings—those with special attributes who are deemed too hazardous for ordinary Mediums, who prefer facing their foes head on—such as the infamous Medusa. The work of a Drifter is not seen by an audience, but felt by the world whenever these destructive monsters can no longer take human lives. (Credit: Co-GM dabombjk)
