Faith Evans is an agent with RLIP.
On occasion I am forced to immediately contradict an opening statement and this is one of those times, twice.
The first contradiction is the name of the person in question. Faith is her real name but when we meet her and for almost the entire first adventure, she is known as Felix Jaynes. We get the idea pretty quick that Felix is not her real name, and not just because 'Felix' is an odd name for a woman, but we will not learn her real name of Evans until near the end of the mission.
The second is that in the first meeting she is an agent but is thinking very seriously in quitting. Then she will. Then she will be brought back. Considering the things that will happen to her, some because of RLIP, it is not hard to understand the switching.
Which brings us to RLIP, or Real Life Immersion Program. This organization is part law enforcement and part espionage. The group is, according to what Evans/Jaynes tells us early on, "a smaller division of the FBI that most people did not know about". She modifies that a tad by adding "we were more of our own entity that the FBI called upon when they needed extra inside on a case, particularly when their own agents were stumped".
Evans at the time of this first recorded mission is only 21 years old and yet she is already a seasoned veteran. She explains this by telling us that she "was recruited at ... a young age. It was my mom and dad who started the program years before I was born". She tells us that they had been FBI agents who started RLIP "to recruit incredibly bright agents who wanted a little more of a challenge".
Once in, though, and you are in for a decade. And once in, your life is really not the list bit your own. While on a mission, each movement is monitored, each conversation recorded, each relationship frowned upon. The RLIP has some pretty nifty toys to play with but when they play, they play rough as Evans and her colleagues will learn the hard way.
