I wonder why Rafagoy was killed?

Does anyone remember how difficult Revan's clues are and what principle they follow? Because from the riddles, only "the Red Book of the Russian Federation" came to my mind (the cross means extinction, the red background indicates the book, and hugging the tree means caring for nature) -> "National Reserve" -> Cop. But it sounds a bit too simple, to be honest.
