Since this is apparently the 100th entry in a series, I can't comment on it in the context of the canon. However, the story works fine as a standalone Dark story in most respects (even if there's specific nuances of character interactions that I'm missing).
Still, neither part really worked for me. The SH portion was alright in terms of plotting out Dark (even if "he's a rich wizard" was a bit of a let-down), but I really didn't care for the meat of the article. The issue was that 1) the footnotes were too-frequent snark for my taste 2) the prose itself felt off. With regards to 2, I am aware that there are plenty of articles (like The Conspiracy of Sigma 3) that are nakedly partisan and rather goofy. Even with those articles, though, there's a way that they're written that feels consistent with other SH articles. Lines like "Though undoubtedly Homo sapiens, calling him human would be an insult to the millions of years of evolution that made us" don't fit that mold for me.
I get that this is also a plan to murder someone (I thought this was a cool touch, btw), so academic tone wasn't at the forefront of the in-universe author's mind. However, it also seems like it's trying to keep a semi-academic tone while also ranting at the same time, which doesn't work. If it had gone full-bore ranting or stayed restrained and academic while also plotting to assassinate someone, that would have worked. Instead, it ends up as a compromise that doesn't work in either direction.
The tale portion was fine, but there was wonky phrasing throughout that pulled me out of the story (e.g. "the burning sensation birth itself down his empty lungs")
I really liked the idea of the SH documentation being used for more than just cataloguing. Unfortunately, it still doesn't work for me. Have to give this a -1.
