The system is simpler now than it has ever been. I went back to the oldest system because that kept our butts out of the fire. We’ve got Listeners (who can report to higher ups through a series of dead drops), Cells (these are groups of agents who get their missions from the listener) finally, at the core are the Agents themselves. You agents are the individuals that collectively make up The Agency.
There is another group among us but, I don’t say their name. Their job is to watch us and make sure that we keep to the motto and don’t get it into our heads to try and “change humanity for the better”. See, in the past, we had quite a bit of power and resources and it was possible that by flexing our network and really trying, we could direct the future of humanity. I don’t know if we were wrong not to but, we all agreed not to do it. So, that group watches us and keeps us in line. They embed themselves in cells at times or operate independently. Either way, they’re for our own good. Trust me.
