This is…clever, I guess I'd say. No vote for now; I'm not a fan of the SCP references plus links to the relevant works at the beginning, and frankly, I don't like Researcher Evans as a character very much at the moment. I don't want to throw the term Gary Stu around, but it's what I'm thinking. He's a somewhat generic Foundation researcher, theoretically lower on the totem pole but doing surprisingly interesting research. And he enjoys haikus about elbows written by a demented tower. That's a little too quirky for my taste.
I do like the idea of exploring the Serpent's Hand more, though, and I'll be watching for the rest of the series. I might end up liking the whole of it a bit more.
