Cyrus is one of the Fallout: Brotherhood of Steelplayer characters. He grew up in a post-war semi-tribal farming community (hence the tattoos). This community had its share of problems with raiders, radscorpions, and the like, but was finally devastated by the super mutant army when he was just a boy. So, like a lot of adrift-in-the-wilderness youths, he wandered briefly, hearing stories about the defeat of the mutant army and the forces that opposed them. It was inevitable that Cyrus would eventually go to join the Texas Brotherhood of Steel. As a soldier, Cyrus is a strange combination of idealist and bad-ass. In short, he is the modern-day post-apocalyptic knight.
