Oh just kill me now..
It seems kind of… Humorous. I'm not sure what to say on ideas. The one technical thing that I must make is that it needs to be a square kilometer of land, otherwise you'll have a straight line one km long.
Overall, it's just… hard to believe. Keep in mind that as the author, you know the entire story, but the Foundation needs to have discovered what it knows about the SCP through observation and experimentation. Currently, the way you just present the attributes as fact seems illogical.
What would make the Foundation think that political disappearances and a cheetah are connected? Where was the cheetah discovered? How were disappearances linked to the cheetah anyway? If the article doesn't flow smoothly and logically, the reader will have a harder time filling in the gaps.
e: tehspaces. Also, out of curiosity, why are you so intent on writing this particular idea?
I'm not the type of person to try an idea, and if it doesn't work the first time just move on. I've tried this out twice, and overall I just don't think it's good anymore. Looks like it's time to start anew. I do however thank you for the feedback.
