Everyone thinks that something will happen in those times when you feel scared. A rush of adrenaline; your eyes see something that is not there, and you hear the faint whispers of something plotting it's revenge, The slightest thoughts of a gruesome being wanting your end; that's when everyone waits for something like the apocalypse. But it only truly happens when everything is ordinary. The birds would be singing their early-bird song and the air would be sweet and the sun would be smiling down on you. And that is when the bloodshed really begins. Wait. I'm only describing when my life went straight to hell. It was quite an ordinary day, the end of the world.
DIARY LOG 557021: Russian psychiatrist-Ivan Braginsky

I had a theory when I was a kid. Those times when you shivered; you know those times that you wouldn't be thinking of anything and you would just shiver. And I mean full body shiver and it wouldn't be cold what so ever. Well I had thought that every time you shiver, that was when you from another dimension died, or something like a kindred soul died. It was quite silly, but that same silly notion made me learn about stuff like "Schrödinger's cat paradox" and "many-worlds interpretation". It drove me to be who-SCREECH-shit-SCREAM-they're here, crap-BUZZ-well this may be the last you here from me-BANG...BANG-even if you are just a box of metal-MOAN-crap!

Question#1: It would have made a good story, when this whole debacle started. I could have written it in my notepad while sipping tea; well could being the key word here. If your officers hadn't barged into my flat and interrupted my examination of one of those creatures; I could have given you a full report on it.
Question#2: Of course I understood the dangers, love. I even tested how that thing would react with humans and animals. Quite interesting if you asked me; did you know that they will completely disregard dogs and other animals. I mean bloody hell, one of those things even befriended a dog; actually that was my favorite test. He had been a teenage boy and the dog had been his pet before he even turned; the dog stuck with him the whole time; that was until it was shot by scavengers, quite upsetting though I had grown fond of watching the pair. But the most...peculiar thing happened, well after the scavengers had been dealt with, the lad bit the dog, thus saving the dog's life!
Question#3: No. That was an idiotic question. You want to quickly dispose of these creatures; I want to study them. And do not look at me as if I have lost my mind, darling. I merely want to finish my story.
Interview 34520: English writer-Arthur Kirkland

You asked me "how are you alive, why haven't they eaten you yet?" Well I will put it bluntly, no? These things, as you put them, are quite smart. They know an opportunity when they smell/taste it. And if I were the military, I would be worried that they are evolving. But for your information my customers have varying tastes. And I admit, I was disgusted when I had to cook humans, but alas that is all they will give me.

I would like to ask you a question. Do you believe in ghosts? There have been many speculations about them, but now I must say that somethings like them are most certainly real, though that may just be a simile. These things walk around, well more like appear. We all know about the top classifications of these zombie-like creatures, the "ghost" ones being the creepiest. They appear randomly and the only warning is a soft whispering sound. Many speculate that this sound is their former voices lost, when they lose the vocal cord. Then there is the most common which are quite generic; shuffling, bumbling things. And the other two who are mainly characterized by one: being only active at night, and showing abnormalities nearing the full moon. And the second type shows abnormality by which nothing is missing from the victims, except all or most the blood and a bite mark that show large sharp teeth used for puncturing, to include that it is the whole jaw that has been wrapped around the flesh...- for more of the article visit page 39
