The ending was nice, but a lot of stuff before that wasn't to my taste.
The article tricks me into thinking it is going to be an SCP article, when, in fact, it is a short tale series condensed into one article. This wouldn't be as jarring if the main anomaly was shorter, and if the three entities were more connected to the keystone itself. Because while I was reading at the beginning, I was forcing myself to continue on as most of it read as fluff to get the other point; moments of them literally going in circles and talking about how weird this is, aren't really entertaining. The action/moving segments, where the characters were actually talking and gaining info and doing things other than turning in circles, were the most interesting and engaging parts. The ideas presented in them alone kept me going despite my grievances.
I wish this article was shorter and more streamlined. Again, the ideas here are awesome but they are bogged down by masquerading as an SCP article when its more tale than anything else, lots of filler of the characters going in literal circles, and not getting to the point quick enough for me to be satisfied with its length.
