Quick review of the PoD version for anyone interested. The book itself is high-quality- even higher quality than the original that was released. Used copies of that go for around the same price that you can get a PoD copy, so there's that. Mine came with the title printed on the spine, though I know this is not always the case...I think it varies by what printing studio your order is sent to, based on your location.
The content is, of course, useful for anyone that wants to bring the Cult into their campaign as an ominous and threatening presence. I mean, undead dragons and a vicious, secretive cult that worship them...I think that's enough of a threat for any band of adventurers to take seriously, don't you?
Like the Code of the Harpers, the book outlines and details the hierarchy, habits, and influence of the Cult. It contains everything a DM would need to present them in a campaign as a threat to be taken very seriously. Throw in other organizations like the Zhentarim and the Red Wizards, and you've got plenty of challenges for a party of any strength or disposition.
It's easy to reccomend this volume, since the physical quality is higher than even the original, and it contains a wealth of information about one of the Realm's most reclusive and secretive organizations.
Unfortunately, my copy came damaged - like every other single softcover PoD I've ever ordered here - but I think that's more a problem with the specific printing studio my order was sent to. It's well-worth the money, especially considering the price of a used copy. Just get this one, as it's (mostly) cheaper and higher quality.
