From the introduction:
This Book offers a ramshackle group of characters for players to interact with, as well as their history, goals, and a base of operations. In addition there are several adventure seeds.
Established February 19, 1868 by Kate Warne, the first female detective in the United States, The Warne Detective Agency offers (mostly) free services for the common people of all recursions.While the Agency will accept payment if you can afford it, they do not expect anyone to pay unless they are capable of doing so (Kate had seen a lot of unfortunate extortion in her years with the Pinkertons and didn't ever want to see it in her office).
