Spencer Garmond is an agent with The Mission League.
That organization, according to Prière, the man who comes to Garmond to recruit him in the first recorded adventure, is "an international intelligence organization that does the Lord's work". He is telling Garmond this because "you've been chosen for the Juvenile Agent Development Program". That man's name is
Garmond, a teenager with a major attitude, observes that this was some sort of "churcher thing" and he complained that "I've got better things to do than hang out with a bunch of Jesus Boy Scouts".
The recruiter counters with his opinion that "God has plans for you, Garmond. You're smart, athletic, and your family has a history in the organization". Garmond argues the first point, noting that he is getting C's in school, agrees with the second one, and then balks upon consideration at the third. He then rejects the whole joining a spy organization idea because he a) had his own plans for his future which entailed practicing until he was good enough for the NBA and b) ?spy organization? - for real? No!
Garmond lives with his Grandmother. He considers himself a near-orphan with his father having run off abandoning his wife and son and then his mother passing away. He loves his grandmother a lot though he could definitely do without her constant church-going and such. He is not a big fan of having to attend the Pilot Point Christian School, either, though considering the amount of trouble he routinely got into, he knows a transfer to the Carlsbad Military Academy was his only other choice.
After a long night of thinking, Garmond was loathe to admit it but he knew that he would be agreeing. This Mission League, whatever it really was, was better than military school and it admitted girls! Who knows, maybe they had a basketball court.
Which is all how Garmond came to be the New Recruit and how he found that, all joking aside, the Mission League really was a bunch of spies and he had just entered training camp.
