In the history of Zetsubo, particularly during an enigmatic epoch in 1986 (although the specific year need not be emphasized), a series of agitational posters emerged, championing an alternative reality known as the Neverback Environment. These mesmerizing artworks beckoned individuals to take a daring leap into the enchanting realm of dreams. Yet, these posters were more than mere aesthetic creations; they served as portals to a realm where the ordinary laws of evolution, time, and existence seemed to unravel. Intriguingly, these posters weren't content with just compelling words but also boasted intricate visuals. These visuals weren't your typical artistic fare; they depicted the denizens of the Neverback Environment, beings shaped by an experiment in rapid evolution. In this curious microcosm, evolution unfurled with a velocity that defied all convention. What set this reality apart was its tendency to accelerate the evolutionary journey of its inhabitants, pushing them toward their "ideal forms" within mere months. It's essential to underscore that the cessation of evolution upon achieving this ideal state was a pivotal enigma in the Neverback Environment. The static and unchanging nature of this realm played a crucial role in this phenomenon. For example, the "Field of Dreams," a central zone within this realm, perpetually existed in a state of eternal summer. The ramifications of this stagnation in evolution left inquisitive minds pondering the boundaries of the interplay between time and adaptation. Of the various species to grace the Neverback Environment, one particularly intriguing group were the Wormneets. These spindly beings defied conventional evolutionary narratives. Their existence sparked profound questions about the very essence of emulated evolution, adaptability, and reality itself. We will talk about them later.

Wormneets come in various forms, but among the most common are the Wormneet-Horses, Wormneet-Spiders, and the more familiar Wormneet-Commons. These spindle-shaped entities bear a striking resemblance to rusted iron, not only in appearance but also in the distinctive metallic screech that emanates as they move, be it in walking or running. Among these variations, the Wormneet-Commons are the ones that most closely resemble humans in external structure. Their class of danger, typically rated from 0 to 5, rests at 1, signifying that in approximately 95% of interactions, they pose no threat to humans, even when faced with a life-threatening situation. These Wormneets are remarkably friendly, often displaying a willingness to communicate with humans. However, their language is confined to the range of metal-on-metal tones, making direct human-like conversation an elusive endeavor. The Wormneet-Spiders, on the other hand, are far more common than their counterparts. With a danger rating of 3, they only become aggressive when they sense imminent danger. It's important to note that engaging in combat with a Wormneet-Spider results in a fatality nearly 70% of the time. Therefore, forming an alliance with them is a wiser approach. Their intelligence, though not on par with Wormneet-Commons, renders human communication exceedingly challenging. The Wormneet-Horses, the rarest of all Wormneet variations, hold a danger rating of 4. They can exhibit aggression without provocation if one approaches too closely. It's advisable to steer clear of them, as they might launch an attack with seemingly no provocation. Encounters with Wormneet-Horses are infrequent but should be approached with caution.

In the Neverback Environment, where the extraordinary is the norm, it's not only the Wormneets that hold sway. Although these enigmatic beings have stolen the limelight, this captivating world teems with other, less common denizens that boggle the mind. One such entity goes by the collective name "The Source." It's a fluid, colonial organism with a unified intelligence that transcends traditional biological boundaries. The "columns" of The Source can be found in every dimension of the Neverback Environment. They manifest as dense, black, glistening liquid, eerily suspended in mid-air. What's even more bewildering is that this liquid, though seemingly immobile, exhibits subtle, perceptible movements, defying gravity and challenging our understanding of the laws of physics. Astonishingly, interactions with humans have revealed no harmful properties, resulting in a danger rating of 0. In essence, The Source remains a cryptic yet benign presence within this enigmatic realm. But there's another category of entities here— the "independent beings." These creatures exist as solitary entities, their singularity making human encounters quite rare. Among these unique beings, we have The Servant, The Silent Man, Butcher, and The Eye. Each of them, with the exception of The Servant (old rusty red robot), harbors extraordinary and, quite frankly, terrifying abilities. These include interdimensional skills like teleportation, invisibility, the ability to be in multiple places at once, mind-reading, hypnosis, and the power to unravel human neural connections. In short, these creatures pose a severe danger, with a danger rating of the highest level — 5. Yet, it is "The Eye" that stands as the epitome of peril within the Neverback Environment. This entity has the capacity to disrupt all our plans and the very fabric of the simulated laws governing this realm. Its abilities are so profound and chaotic that it threatens to shatter not only our understanding of the Neverback Environment but also the fundamental principles of reality as we know it.
