Cyrus Cooper is an agent with the Coalition.
Is the Coalition a secret law enforcement agency as a blurb for the first recorded adventure indicates or is it a covert intelligence agency as is actually said in that adventure? I go with the latter since that source is more official. For me then the question became whether it was governmental or private. The lone explanation I found so far states "They routinely ran undercover infiltration operations all around the globe. With a fraction of the manpower of the CIA, or even the NSA, it was easy for the group to stay off governmental radar and free from restrictive political red tape. They were a small but effective group that ran tight operations, often with significant and far-reaching effects—though few even knew of their existence."
Cooper is the youngest agent with that organization. He got involved with them during an "incident" while he was attending Brown University and as a result of helping out a Coalition agent resolve the matter, he got himself noticed. "By the time all was said and done, it had become clear to the powers that be at the Coalition that Cyrus was an ideal fit for their organization."
"First of all, he was far younger than any of their other operatives. That gave him the unique advantage of anonymity since it is common for people to believe the young to be equally inexperienced, and therefore less threatening.
"But Cyrus’s number one asset was his eidetic memory. He had near perfect recall of everything he saw and heard. It was a genetic gift that allowed him to excel in his academic career, but it had proven even more effective in clandestine operations. That, and his natural ability to remain clearheaded under pressure, had come in handy nearly as often as his cognitive abilities, making him a true force within the Coalition. As much as his age was an asset in his line of work so, too, was his mind. After a few drinks, [his recruiter] had been known to boast that Cyrus was born for this kind of work."
