I think the use of this post to other campaigns is that outlines an academic treatment of a popular academic text. Being that it is a history, then perhaps it could easily be translated into another world with a view word changes. We want the characters in our worlds and campaigns to have access to a culture so that they can hang their personality quirks on it and to give them a chance to rally around or against something. A book of the elite such as this which appears similar to The Persian Expedition, Parallels, War with Hannibal or the Mort de Arthur would be useful prop for a character.
However, I think this write up does not go far enough and that it lacks any real hook. I understand the value of vagueness in RPG writing and I know that something suggestive is often more useful then something specific, but this item is too far into the specific realm to be suggestive. Yet it also lacks details and a thesis, and therefore we come away with little sense of the intended or actual meaning of this work to the people that might right. I hope that CP comes back to give us a more complete picture, because I like the idea behind this post.
