The first Great Collapse. 7 years ago, in downtown New York City, a portal opened connecting to another world, the realm of the Beyond. After an intense flash, the city was plunged into darkness. In one night, New York was engulfed, destroyed, and rebuilt by the effects of the catastrophic connection to the other world.

From that other world emerged the beings of the Beyond, the "másallíneos," creatures mostly of indescribable origin and aberrant appearance. A massive number of them invaded the newly taken New York, many "másallíneos" transformed the city to their will, others obeyed their shapeless nature and generated violence, and finally, a large number survived the chaotic state that was the Jerusalem Plot.

The Jerusalem Plot was the name given to New York City, once the portal's fog was contained within a barrier. That limiter was born from the portal itself and contained the expansion of the other world onto Earth. It was in this environment that, day after day, newly conceived demons emerged from the contact between the worlds, a type of all-powerful and sentient existence that, after grouping together, became known as the Thirteen Kings. Thus, for two months, through the actions of the self-proclaimed rulers and the active protection of an enormous divine curse in the form of a maritime entity, the American government lost control over one of its most important cities.

Demigods, powerful beings born from the portal of the Beyond, pressured from the interior and exterior of the barrier to create an opening for dialogue in the Jerusalem Plot. Shortly after those two months of uncertainty surrounding all of New York, an official contact was made between the American Nation and the Abstract Realm of the Beyond, a conciliation. Under the Chrysler-Galadona treaty, the conflict with the forces of the incomprehensible was resolved, the sovereignty of the Thirteen Kings was dismissed, the shared state of New Jerusalem was created, and the foundations were laid for "másallíneo" and human coexistence. The barrier dissolved, forming a vortex of amalgamated fog, thus the name New Jerusalem was born.

The city of New Jerusalem originated as a combination of characteristics between the human world and the Beyond. Half of the humans engulfed by the portal reappeared miraculously in the new city, while the other half would appear periodically 3 years later. The beings of the Beyond assimilated the human way of life in the city as a rule to ensure their stay. In this way, a strange daily life emerged involving humans and monsters beyond comprehension. By integrating into the new nation, the "másallíneos" eventually gained citizenship rights and a moderately decent reputation.
Every day, and in cooperation with the new and abstract intelligent beings, the human world recovered from that great imbalance. Although within New Jerusalem, the forces of the chaotic and the absurd remained active, attacking the city in unexpected and desperate ways. Even so, entities from the human esoteric world such as the Spiritual League and other organizations managed to keep the madness of the other world at bay and provided stability to the fantastic and grotesque city for three years. This was until, after a succession of unfortunate events, such as an arcane threatening factor, an overload of effort on human hope, the release of various unknowable powers from the Beyond, and a thirst for demonic self-discovery, a massive and catastrophic second Great Collapse was gestated almost by pure chance.

The second Great Collapse. 4 years ago, south of Manhattan Island, on the artificial island Pandora, known as the base of the Asylum Pandorum prison, a portal to a new dimension opened. Distinct from the Beyond and the human world in its entirety, the dimension with which contact was made was of such an incompatible degree that, a millionth of a second after the connection to the other world was established, the portal closed, unleashing an energy charge so potent that it destabilized the mystical infrastructure of New Jerusalem.

Capable of foreseeing the future, the invisible curse at the edge of the city, a high-degree enigma from the Beyond, used the force of a divine contract to keep the imminent deformation at bay, but it was not enough. For 20 seconds, the city was enveloped in complete calm, until in an instant, all of New Jerusalem was divided in two. Each part of New Jerusalem immediately replicated, thus giving the vision of two parallel cities, seen as through the edge of a mirror. That scenario was witnessed for only a few seconds until the city underwent the same partitioning phenomenon again and again, at increasingly smaller intervals of time. Exponentially, fractal chaos took over the city, duplicating dimensions, dividing time, and brushing against the abstract limits of what is permissible in reality.

The emergency gave rise to a new type of barrier against the mystical fog, of infinite extent, total light absorption, and intangible. This and other feats by the Spiritual League and other organizations, such as rescuing the vast majority of living creatures in New Jerusalem, provided relief in recovering the city or preventing a greater tragedy that would this time fall upon the world. Even so, it was during this short period of infinite barriers that the city was considered lost. Fractional Nod, an abstract wasteland of wandering march that only concentrated disaster.

Miraculously, almost a month after the Second Collapse, the fundamental constants returned to their initial values and the city was rebuilt. This time giving rise to the Sacred Land of Nod, a double parallel city composed of Nod Thrillfair and Nod Issel-Sarexuglactrella. The new city encompasses duality and the indistinct within the identical. It is from this land that the world still feels the effects of chaos, for better or for worse, recovering millions of humans, or having to deal with infinite races from Others, other worlds, and time.
