Ben Keegan is an agent with Dark Horse Guardians.
Lara O'Connell is the owner of an architectural firm.
Keegan is given the starring role here but O'Connell is just as important to the events in the recorded adventures. In fact, we meet her first and learn how she knows the kinds of evil that exists in the world. And how to deal with it.
We are told in the prologue of the first adventure how she was sexually assaulted and nearly beaten to death as a young teenager by the son of a rich member of the town she lived in. We learn about the years after the rape and how she had to learn to deal with it, especially after the rapist got a slap on the wrist since he was 17 at the time. But mostly we find how she, when she was celebrating her 21st birthday, tracked down the now drug-addicted assailant. We read how she shot out the streetlight before he arrived and then watched him approach. He is found later by the police, the newspaper reporting he was dead from two gunshots, one to the head and one to the heart. After she read about the incident, "Lara folded the newspaper with no emotion".
Back to Keegan, we learn that he attended the U.S. Naval Academy, entering in 2001. Following graduation, he received "special training", as he modestly describes it to O'Connell shortly after they meet. That training came as he earned his way into the elite SEALs, serving with them for six years in Iraq and Afghanistan. Still low-playing it, he tells her he retired from the Navy and "In 2012, I started a small consulting group and now work as a contractor for the government".
That company is Dark Horse Guardians. While it is said above he is an operative with it, which he is, he is also the owner. We are reminded of the meaning for the first part of the company's name in the intro to each of the adventures. "A dark horse is a little-known person or thing that emerges to prominence, especially in a competition of some sort or a contest that seems unlikely to succeed". The name is an interesting and telling look into the company in that it is one of several private firms used by the CIA to handle situations that are deemed vital to the security of the country but which the Agency would prefer to not be publicly associated with.
When the adventures begin, Keegan is the operative in the field and O'Connell is the reason he wants to survive to go home to. As time passes, life will push O'Connell to become as much a part of Keegan's professional life as she is his personal one.
