After finishing the Description, I was thinking: Yeah, this is unsettling enough that the article doesn't even need further expansion on the idea. That is to say, you have a good thing going in the bulk of the article. My only point of contention is, the early mention of the anomaly killing people (Description paragraph #3) comes too soon ,and undercuts the reveal. I think you could manage to lightly restructure that area to preserve that reveal a bit longer.
Then, the addendum came. I really did not expect the story would be able to build an entirely new dimension of fucked up. But it managed to! I agree with Xunu that the connective tissue between two halves isn't as strong as it could be, but it doesn't get too in the way of the fact that what's here is surprisingly vivid.
Great work!
