Okay, the writing here is pretty solid, but I'm not sure how much I enjoy the concept or how it's presented. It doesn't do all that much for me to differentiate it from some phenomenon that makes you go slowly crazy. While attempts at giving depth to the concept are recognizably made throughout, it still falls short for me.
There's some imagery in here that's very evocative and interesting (particularly the organs inside the tree detail), but it isn't enough to save it from me finding it very basic in the concept's resolution, and to an extent, finding concept itself a tad basic too. It doesn't help that it plays into the rising horror cliche of "Don't [verb] the [noun]" towards the end. The Cragglewood crosslink didn't add all that much besides a arbitrary connection to another scip about trees, which didn't do much to up my overall enjoyment of the article. Maybe I'm missing something in a form of connection? I haven't read 2571 in a while.
For this to work for me, it would need to do more in the horror department for me to find more enjoyment in it. Maybe there's a way to expand on that evocative imagery in the article? You got something going here, but it just feels a tad too basic in terms of horror as-is.
