This book is designed to provide keepers with a civil, geographical, cultural, political, and a Mythos tour of Morocco during the 1920s and 1930s. The majority of the material in this book is factual, though there are numerous portions that have been elaborated upon for use with Call of Cthulhu.

Because of the vastness of the country, not every city can be covered in detail. Instead, this book explores the political capital, Rabat, and the economic capital, Casablanca, of Morocco. Additional maps of cities are included, with character templates, optional skills and rules, as well as numerous NPCs to bring Morocco of the 1920s to life.
