A secret society of little guys looking out for the other little guys - that's kind of neat. It's a good concept that I wish had been expanded on more. Here are some things I'd like to see expanded on:

• A description of what the Meretrices think of the various Nations and Secret Societies as well as possible conflicts and alliances.
• Some fun plot hooks to draw heroes into the story outside of the earning and spending favor that can help me link the organization into my campaigns, and
• An NPC or two that I can introduce to my Heroes so I don't need to just make something from the ground up.
