Berin Kinsman reviewed Book of the Wyrm in White Wolf #38 (1993), rating it a 3 out of 5 and stated that "This is an excellent sourcebook, but as much as I think the Wyrm makes a challenging villain, I've also found it to be one of the more contrived elements of the game.

Where Vampire took all the various legends about bloodsuckers and forged them into a coherent mythos, Werewolf is made up largely of whole cloth.

Because the Storyteller System is horror-based, a Cthulhuoid menace was almost mandatory, but I'd have preferred defining it in a generic accessory, along the lines of the World of Darkness series, to making it an integral part of the Garou mythos.

"[1] The reviewer from the online second volume of Pyramid stated that "Starting with a short story entitled "Ill Winds," the book is packed full of attitude, information, and background of the Wyrm.

Readers will find inside the history of not only the Black Spiral Dancers, but full tribal information as well.
