<>Before there was the known universe, before there was creation, and even before there was simply light....there existed a darkness. Not just the absence of light, a true darkness that existed outside the universal laws that govern reality. Predating the original demon, the Soul King, and all life and unlife, That Which Came Before is truly the definition primordial. However, unlike the beings previously named this Original Darkness is not really a sentient creature capable of thought processes or willful action. No, it would be much more accurate to compare it to a virus for multiple reasons. That Which Came Before physically functions as a virus, not having mental thought or willfully doing anything besides surviving. Speaking of which, the only cause for any action or change involving this ancient thing is survival, just like a virus.
The living world can be extremely thankful for the creation of light, which was able to successfully cast away the darkness, for the universe as we know it not just in the typical sense but also because had this not occurred there likely wouldn't be anything left for the primordial blackness to consume. Had That Which Came Before been allowed to continue its existence in any of the known dimensions or universes or timelines, it very well could have reduced everything to nothingness simply by existing. Not on purpose, mind you, but that's just how the
thing functions. Like a virus it infects anything living, or even nonliving, and uses it as a host until said being degrades to the point of death or absolute decay (meaning a person is infected by it long enough, currently being Stefan Soan, they will die), and then it moves on to whatever else it can latch onto (for RP purposes this requires permission from the character owner). However, like many viruses it seems to prioritize certain targets: The hungriest (not necessarily for food), the strong, and those susceptible to possession.
However, to call it evil or sinister would be a mistake. The Original Shade is best described as being
above evil, good, or even neutrality. It is neither good nor bad, and even though it degrades and decays those it infects, it isn't truly destructive. Nay, it truly is survival given form. With no purpose other than not being eliminated and continuing on, the Darkness should never be underestimated as morality and emotion are as foreign as possible to it. What this means is attempting to take advantage of it or using it to further your own goals can never result in true benefits as it will only lead to the end of everything and everyone involved. This characteristic is perhaps what makes it so dangerous, as it has no biases or preferences and cannot actually be manipulated by others.
You may ask why this
thing isn't still locked away in some other dimension or in between world. Well, for billions of years it
was. The dimension it had been cast off to was like the pre-light universe it used to reside in: Completely empty and devoid of life. This meant it essentially sat still in a dormant state, in a sense frozen in time. If left untouched, this could potentially go on for billions of more years, or even forever. However, a certain Vizard named Stefan Soan unwittingly released the Darkness unto the world by repeatedly using his Zanpakutō's special abilities during training sessions. While usually these abilities involve a void dimension within his Zanpakutō, the over-usage of the ability resulted in a tear to another, hidden realm...the empty realm the Darkness resided in. This tear existed for a fraction of a second, but that was still plenty long enough for it to pass through and infect Stefan before he was even given a chance to react. This infection has quite a few positive and negative effects on the host:
- Dark Personality Enhancement: While not related to the host's powers, the primary change resulting from being infected by That Which Came Before is a significant enhancement of the victim's negative personality traits. Not only does this mean their hatred and disliking of things are both amplified, but they also gain more negative feelings and personality traits. A regular person would become sadistic and hate-filled, as well as gain an extreme lack of empathy. However, this is even more noticeable in someone who already holds disdain for a lot of people and things, such as Stefan. Extended possession is more dramatic, turning the victim into a beast-like monster that wishes solely to destroy everything and everyone around him, though this takes quite some time to come into effect.
- Semi-Immortality: The infected, thanks to the actual immortality of the Darkness, gains an immunity to death by most conventional means. Stabbing him or her through the heart would result in little more than inconsequential blood loss. Even cutting the host's head off wouldn't kill them as their body would just pick it up, put it back on, and it would reconnect. This also applies to legs and arms, as well as the torso. Slicing and dicing him into many little pieces would just make the reuniting process longer, even if each chunk was placed in cement thousands of miles away from each other. Whether it takes a minute or ten thousand years, the pieces would eventually reconnect until the host is whole again. Unfortunately, this has a few pretty serious downsides. The first drawback is that actually cutting the host up into pieces and spreading them apart not only works to subdue him for a pretty massive amount of time but the Darkness itself is also kept from switching to a new victim until the old host is fixed up. Also, as the host's negative traits are enhanced, they become more and more reckless in combat to the point of not even bothering to dodge incoming attacks, resulting in a much easier process of subduing/damaging them. It should also be noted that if he gets low enough on energy, or runs out completely, the separated body parts not only take longer to return together but sometimes stop moving completely until he is able to regain some power.
- Power Changes: First off, That Which Came Before gives the host relatively significant boosts in essentially all aspects. This applies to their physical attributes as well as their spiritual weapon and their special abilities. This increase is especially difficult to deal with, however, as it's less an actual power boost and more of a forceful push past the host's limits, which puts strain on their mind and body. The strain is more extreme on stronger hosts as the limits being breached are higher and more difficult to push past. This is more stressful to the host over time, hence the self-destruction that eventually occurs. This "boost" actually slowly ramps up over the course of a thread, which makes the stress especially worse because, coupled with the personality changes, eventually the user's body starts degrading (appearing as black, rock-like degradation starting with the hands and feet). As the body degrades, it becomes steadily more and more powerful until it reaches the climax level of absurd power. Unfortunately, this maxed out form, in which the host appears black and demonic, lasts a maximum of two to three posts until they face the complete destruction of their body and mind.
Mainly plot reasons, and the backstory is already stated in the description.
