But the particles themselves were infused, of course, with the powers of Creation and Destruction, meant to serve as a weapon for protecting Hell itself. No, it was not as strong as the embodiments themselves, but it would serve as a viable defense against Chaos. The particles, broken down from the hot sand of Hell, were coming together to form Gravefire... Not Hellfire, but Gravefire, a fire meant to represent South's raw power of death itself.
The Gravefire was working at burning itself into Keith, infusing the very idea of death into Keith himself (seeing as he could not die normally, as he was not alive). But it was having trouble... It had to fight through the chaos first. To do this, it started to try and "kill" the chaos.
Meanwhile the Hellfire on the Club Frags was easily corruptible, unlike the Gravefire. Remarkably, as the club frags fell to the ground, the fire DID begin to spread. In an attempt to suffocate the Chaotic Hellfire, Vincent began to suck the oxygen out of the area around the fire, hoping to suffocate it. With that extracted oxygen, he began to cause it to spin. As it did this, it quickly picked up fire and sand. A vortex was forming before them.
But when Keith began to challenge Vincent's bond to hell, his goop spreading, Vincent knew what he had to do. He wouldn't allow Keith to take his spot. He began to concentrate the pure, rotting decay of Hell itself. Intensity. He focused this decay on Keith itself -- effectively, he was using the entire realm of South against Keith. How? Accelerating hell mutation. Keith, and the red goop that he was spreading, would begin to rot, die, to be mutated by Hell -- not into one who could control Hell... No... Vincent was changing Keith into a "demon".
