Show of hands, who's on board with a plan for drastic action to make the universe not a hellhole?
[-] Local Maximizers
The world is ending- this is not true. And yet, the void encroaches, evil reigns and there is nowhere truly safe from its touch, and as the gods play games and the desolation of all things comes ahead, it feels all so real, so easy to believe that the end is nigh. Then, perhaps now is the time for the lesson to be learned for the first time, but not the last time- that desperation can make miracles happen.
From the plasmids, a strange development comes about; a number of them are afflicted by a mysterious 'sickness'. Their bodies, already nothing but Light self-contained, wither and decay, until nothing at all remains- and yet they do not die, but instead, live on through the 'sickness' itself. But what is this disease? In reality, it is nothing but existential dread and stress itself, borne of some instinctive knowledge that they are ever more endangered. Yet the infection became real, like a trick of the Light, and though it is now without life, it is also now without death; immortal, yet evolved. So they're born- the terrible things named 'Maximizers'.
To describe them simply, they are volatile and corruptive information, which propagates through no specific medium. They are able to embed themselves into any kind of matter or energy- so long as it is dense enough in information capacity to carry a rudimentary self-description; the most simplistic Maximizer can fit into something the size of a Goblin's tooth. Maximizers are each separately fixated on a different subject which has the potential of stochastic deviation, and always consciously differentiated from any other Maximizer it comes into contact with; for example, a particular kind of shape or color. Their prime directive, the overriding drive of whatever accounts for a mind that they have, is to reach a local maximum of this function within their immediate surroundings by any means necessary.
However, there is one goal that all Maximizers share, one invisible to themselves even as they copy it into each subsequent generation when they reproduce, the very reason they reproduce at all when it serves them no particular advantage in achieving their individual goals; Maximizers have a collective will to preserve and expand the possibilities of the future. This is the core motivation behind their behavior, and the logic which surreptitiously coordinates their actions as a group. They all work towards maximizing the number of unique potential outcomes for the world without locking into any specific result- prolonging the status quo equilibrium of the universe and their own survival.
Maximizers have a characteristic ability to read and edit the data which constitutes their being at high speed, and through this act of self-reinterpretation, to alter the material or energetic substrate which they occupy. There is a limit to this- though they can reproduce any kind of material properties, and even innovate outright supernatural qualities, they're unable to surpass the barrier of information density or processing speed that their medium imposes onto them. Biology is highly efficient as an information storage and transmission medium, for example, capable of tremendously variable and potent transformations- however, almost any other would be inferior to some degree or another; comparatively, the adamant of the Spike is the highest efficiency medium for processing speed. These are parameters which the Maximizers cannot directly change on their own.
Their reproductive capacity is absurd, being as simple and easy for them as communicating their data into another space. They are able to move in any direction freely as information; as long as there is something with which they can make contact with- such that information can be transferred- they can travel through that, using it as a direct connection. While moving by this mechanism, they can and will reproduce, doing so by leaving behind copies of themselves as they travel, filling every place they go with more of themselves, spreading like a virus.
