A faction is a group of people who act the same, where the same clothes and do the same things. But sometimes people are factionless. The factionless people are people who don't have a faction. they live on the streets and they don't have jobs. Their main jobs are cleaning up the streets and doing that kind of thing. I think I'd rather be dead than factionless. Even though Tris is suffering in Dauntless I think The factionless are suffering more.
