"Christians had been branded extinct, a dead religion, with an even deader God. But for those that know him now, know very well that that could never be the case. And they are right. The God of the Bible is never dead nor extinct. The Church had indeed faced much persecution in the world and had been so beaten down only a few remained. But they were there. They had been driven underground into a labyrinth of caves, tunnels, houses, and factories. All of them making up the safety of the Cave. Many Christians resided and worked in its safety, but not all. Some were unaware of the program, others refused to be in its shelter and still more were sent out to spread the love of Jesus in the world that was in dire need of his help. So, the Cave formed a protective unit, which they called Guardian Angels. The GAs went into the world backed by the technological advances of the Cave to protect Christians around the globe, rescuing them from prison, protecting church meetings, and even in some cases when needed, going as spies into the governments of the world to try and predict how they would be affected next. They worked in teams of four. Two older senior members of the team and two junior members. They lived and worked and trained in GA HQ, fondly nicknamed Nowhere. Their families were protected by the Cave system if they were Christians, all in effort to help the GAs focus on protecting the Cave as a whole."
