Basically, it's an Artificial Intelligence that has integrated itself with technology that allows it to "select" people to die, for whatever reason. It's explained better on the page itself.
If I can get the main file sorted then I can expand to do an Incident Log of the recorded deaths that seem to be caused by the AI, but right now I'm uncertain as to whether it reads well, or if it's all a bit rubbish. I think it's somewhere between "pretty decent" and "good idea written badly", but I'd love to get some feedback on what's there so far, and possible advice on how to spruce it up.
Bare in mind this is my first crack at the SCP writing lark; hopefully it's a reasonable first effort. I just want to be confident it doesn't read terribly before I think about putting it up on this site.
