This is a book for White Wolf’s Werewolf: the Forsaken line, detailing the “bad werewolves” of the setting. Naturally, with it being a horror game, the “good werewolves” are not exactly models of virtue and restraint, but they are supposed to be much more sympathetic than the Pure. The Pure are driven by an unwavering belief in their own virtue, and a genocidal hatred of the Forsaken, the “good werewolves”. They are the religious fanatics, the “master race”, and the merciless hunters of the setting.
The book struck me as a solid, workmanlike performance that covered all the necessary bases. But it didn’t inspire me. This could be just me, of course. There’s a lot of material in it, and plenty of things that could be used in a game to showcase the ways in which the Pure differ from default werewolves, so anyone who found the Pure inspiring, whether as villains or as flawed protagonists, in the core rules would probably find a lot of good stuff here. I never did, and that may well be the problem.
On the up side, there is plenty of material here that I could use if I decided to include the Pure in a game, and it would certainly save me a lot of work; there are sample characters, Rites, Gifts, and fetishes, and discussions of the sorts of things that the Pure get up to. But that extra spark is missing. In the terms I used when marking essays, it’s a solid II:i, but it’s missing that something special needed to make it a first.
