A player in my campaign is playing an agent of the Emerald Claw and, recently, he brought up a good question: if he were on a mission in a city he was unfamiliar with and sought the help of other Emerald Claw agents, how would he go about doing it? Simply asking around is likely a fruitless endeavor. More importantly, once he did find another member, how could he prove that he was a member himself? Carrying around a badge or symbol would be dangerous if you were caught by the authorities, I imagine. Secret phrases can be compromised, and so forth. How would you handle these issues?
