There's something wrong with this office, a creature lurking in the shadows. Ever since I joined as sysadmin it's been doing something to the computers. They break every now and then, giving me a ping on my tablet. Then I gotta go check it out. That's my job. To fix computers, not exorcise demons.
I'm just outside the server room when I see the dark, scaly tail. It's crawling away to the south. The computer has a strange red glow this time. The screen is all messed up. It's gonna take a while to fix this one, I can already tell.
I hear a scream. Sounded like one of the programmers. I run towards it - in the direction the thing slithered off to. It's Jim. He's hunched over with his hands over his face. There's a large scorch-mark by the door frame. It was trying to get away when Jim entered the room. It looked him in the eyes - just for a moment - before it vanished in a burst of flame. A moment he'll never forget.
