From the publisher:
"Welcome to the twilight world of conspiracies, the world of Sub Rosa. In the shadow of Aegis and Black Book, hundreds of other organizations operate. They have their own agendas, ranging from gaining personal power, to learning more about the supernatural, to forcing the government from power.Whatever your characters think they know about the world of secret conspiracies, they are wrong.

Sub Rosa includes several new conspiracy types, how they operate, who they recruit, and how to play them as part of Aegis, as opponents or as the home conspiracy of the characters. A new character creation process is presented, with many new professions. Finally, the book contains a conspiracy creation section that allows you to create any conspiracy you can imagine."
