The Processor is an amalgamation of bodies and mutants that is the leader of the organization known only as the Mass, a faction of mutants in the western Outlands. The Processor follows the will of "The Mass" and attempts to unite the world by consuming and incorporating all of its flesh into itself.
"The Mass does not know death. It does not know sorrow. Only change. What is a thought compared to the Mind? What is your tiny individuality compared to our glorious Mass? Join the Mass and you will never again be weak, alone or helpless."
The Processor began its existance as the meta-minded hive mind of the shadebeasts of the Shadow Realm. With the exploitation of the Shadow Realm by the Ithonair, the Hive Mind was made aware of Dunia and the destruction wrought upon the Shadow Realm by the Ithonair made it aggressive and vengeful against Dunia and its inhabitatants.
The Hive Mind eventually succeeded in its invasion of the continent of Celenia and wiped the Ithonair out. With their enemy destroyed and no more exploitation of the Shadow Realm present, the Hive Mind and its subjects returned to the Shadow Realm.
The Shadow Mages
Eventually, another civilisation, the Kykr, arrived on Celenia and discovered Shadow Power. Their exploitation of the shade was not as severe as the Ithonair, so the Hive Mind was content to let them be. But when the occultists started breaching the Veil between the worlds and enter the Shadow Realm, it took offense and began working on a plan to wipe out Dunia once and for all. It could not tolerate their incursion into and exploitation of its home.
The Occultists were eventually defeated by the Kykr and over the course of about a century, the Kykr researched the properties of shade, as they had come to call the energy from the Shadow Realm. The shade, when brought through the Veil separating the worlds, was a thick, viscous fluid that had great energy density. While the fluid was highly reactive and dangerous to anything living, the Kykr found that with proper precaution and shielding, they could exploit the energy content within the fluid. Once the process of extracting the shade's energy was fully understood and perfected, Kykr society skyrocketed into an industrial revolution.
This wreaked havoc upon the Shadow Realm and with so much energy being drained on a daily basis, the physical fabric of the Shadow Realm began to fall apart. Entire regions fell into the vast empty abyss, land was shattered and foul weather ravaged the lands. The Hive Mind desperately attempted to combat this, but with so much energy being stolen, there were scant few ways they could find a way to breach the Veil and strike back at the Kykr. Any attempts at attacking the shadow plants directly was met with failure as the Shadebeasts who followed the flow of energy were ripped apart on the other side.
With the continued exploitation of the Shadow Realm, its core binding energy was eventually drained, causing the entire dimension to collapse into a singularity. The force of the collapse made the Shadow Realm explode like a supernova, it's searing, corrupting, toxic energy being flung through the conduits into every shadow power plant in Dunia. The Cataclysm ended Dunia in an instant. Almost everything and everyone was destroyed.
The Hive Mind, lacking a physical body of its own, was torn apart when its subjects were vaporized by the energy of the collapse. It's shattered remnants were fused with shade and flung into Dunia where it ended up in the western Outlands as nothing but a scattered rain of shade.
It took years, but eventually the Hive Mind managed to coalesce the scattered pools of shade and fuse into a shapeless blob, composed entirely of toxic shade. It soon found that it had the power to corrupt beings of Dunia and when it fell upon a settlement, it caused its inhabitants to suffer horrific mutations. It brought these mutants to itself and fused them together into a horrifying flesh-creature that it dissolved its shade body into. The resulting creature became the Processor.
Having merged with the formless pile of flesh, the Processor attempted to gather its mind. Shattered, driven insane and utterly alone it tried to seek out allies and friends. It's merging with organic, living matter made it obsessed with flesh. It had never before experienced such a thing as existing in a physical sense. It found the experience exhilarating and euphoric. It became obsessed with flesh shaping and its own, twisted idea of physical perfection. Everywhere it found other creatures, it corrupted them with severe mutations, seeking some elusive perfection. It gathered a following of mutants who began to worship the Processor as a god, or at least a leader. It now had a goal: It would unite this world in the flesh, transforming it to it's new home, it's new hive. Or it would destroy the uncorrupted for what they had done to the Processor's home realm.
A faction of true mutants, led by an enigmatic entity only known as the "Processor", hellbent on converting the world to mutants. They believe ascension through mutation is the only way forward for the evolution of the world.
The Flesh Pits
The Flesh Pits are the rumored "home" of the The Mass and its abominable leader, the Processor. Said to be a "sea of flesh" where organic creatures are processed and incorporated into the Processor.
Cyst of the Mass
The Cysts are fleshy amalgamations of bodies and function as psionic amplifiers for the Processor in order to extend its compulsion field.
