I expected A Brief History of Gnolls to be an interesting read, and it is. But more than that it's FUN. Much more than just a brief review of the creature itself, this piece takes a close look at references to gnolls in fiction and the gaming world and makes a convincing case of the connections between the various (and sometimes very physically different) beings bearing the name "gnoll". Loved all the detail, and the amusing choice of quotes about the gnoll. Gives an excellent feel for the creature while looking at its creation-history.
Well-written, clearly presented, and definitely worth a download and a read. The graphics are a fun complement, especially the Gnitted Gnoll.
