the Crettondru

As the window is formed, all the young man could think about is the destroyed area he had left. He wondered just how much destruction would be there to welcome him if he should appear there. He imagined that perhaps the Sinigrattians--or, as he knew them, aliens--had turned the place to oblivion, but when he takes a step forward, he stops for a moment.
            
            "What... the fuck?" He looks at where he had "stepped", now dumbfounded. He had forgotten that he had previously been unable to walk or do anything within this area until he actually performed a step successfully. This was now baffling. 
            
            He imagined that this was perhaps a sign, so instead he wasted no further time and rushed through the gathering of white particles, and as soon as he steps through the window, the gathering of the particles disperses throughout the realm once more; the young man leaving no trace that he was ever there.

That's when another fragment of reality slapped the man in the face. He was still stuck here. So he thought. 
            
            He didn't know anything right now other than that he was changed and he was still where he was before... he fell asleep. He distinctly remembers the feeling of being hit, and that piqued his curiosity. He looks about the realm, and notices something different about the realm.
            
            The difference was only visible to him. He could see things moving about. They were quieter than death itself, but sure enough, he could see them. He saw one of them randomly disappear, and in that brief moment of its disappearing, it had traversed through a series of white particles. 
            
            This interested the young man immensely. He knew he was changed, and if the change was because of something within this realm, then maybe he could start to do things that these transparent beings could do. He didn't know if they were sentient or not, but he had no other theories to try.
            
            The man looks around in quiet for a few moments, looking for different white particles. They reminded him of stars in space, actually. It was quite interesting to him.
            
            'Enough distractions', he thought to himself and tried imagining the white particles gathering together for a window in front of him. Having no other image in his head to imagine, he imagined making a window of white particles similar to how the Sinigrattians had done to get him here. 
            
            Slowly, but surely, little white specks started flinging together, gathering and clumping together progressively faster, slowly building a sort of two-dimensional window in front of him.
            
            "Hell yes."

The young man woke up violently enough; he crosses his arms over his chest, and they split themselves into an additional set of arms, splitting all the way up to the elbow joint, and these arms appear ready to punch each others' knuckles, and when he swings his crossed arms apart, at the same time, the two additional arms extend enough fairly oddly, the skin appearing to rip and stretch a little in the attempt to do so, these fists smashing into each other before the force of the swing of his bicep/triceps would pull the arms apart. They would then reattach to his original arms without any indication that the arms were even there. 
            
            The man also screams as he wakes up, his body jerking upwards as if he were lying down against something solid, his lower torso still down as he "sat" up in the empty realm he was within. 
            
            His scream echoed throughout the plane for an unfathomable amount of time; even though it left his own range of hearing, the realm, having nothing within it, would echo throughout. 
            
            He still had difficulties breathing, remembering just where he was. He had to breathe in consciousness; he was still partially human like he once was. But he knew something was wrong, and that he was changed. He had no idea why he knew this, as he hadn't seen the spectacle of his arms just yet, though.

What happened next was completely out of the young man's imagination. He couldn't see it coming, he couldn't hear it coming, there was no warning whatsoever. All of a sudden, he just felt his entire body be slammed and then start to crumble. 
            
            It was not a crumbling as in he was curling up. It was literally his body falling into pieces, the pieces floating away lifelessly. He would scream, but his head was not constructed enough to do so. He literally broke into pieces. He would be dead, however something started to cause the pieces to be pulled back together.
            
            Not quite having a brain anymore, the young man was literally lifeless as his body was pieced back together. Something was putting him back together. And he wasn't even awake to know it. 
            
            By the time all of the little crumbles of his body were pieced back together, his brain had been reconstructed and then something gave him life once more. He was asleep, though. It was not a light sleep as if he were tired; it was a hibernation. He would be in a deep, coma-like state while his body adjusts to its unseen changes. 
            
            Something was changing about this man, and he wasn't even conscious to know it. His memories would be reconstructed in due time, as well. 
            
            This was the start of the change.
