As a long-time Castle Falkenstein player and Host, I jumped at the idea of a new supplement for the game and I was not disappointed. The first thing that I noted was that I now had the mechanics for a character based on Rudyard Kipling's Mowgli, or some of the American Legends (Davy Crocket comes to mind). The idea that the narrator was the young apprentice of Doctor Doolittle was particularly apt. This book also provided a mechanic for something I felt had been missing from New Europa's magicks; Familiars. Now if a wizard decided to keep a black cat, or a raven, as a familiar, there existed a mechanical advantage (and some disadvantages) to doing so.
Altogether, this book was fantastic, and I look forward to the opportunity to bring it into my future Castle Falkenstein games.
