There's a wall that protects the city, no-one knows what is outside the wall of the city, but only two know. One is Jeanine Matthews, she's from Erudite. The other is factionless, her name is Lauren Eaton. Her son is Tobias Eaton, Tobias is from Dauntless he was originally in Abnegation but transferred at the choosing ceremony.
The choosing ceremony is a ceremony when a sixteen year chooses their new faction. Their new faction is determined by their altitude test. And altitude test a simulation of different trials determining which faction you belong to. Everyone belongs to one faction but, there are divergents. Divergents don’t belong faction but belong to all of them. But divergents can belong to one faction more than others, that causes them to not be as much as a divergent as others. Beatris is full divergent. Just to give you guys a heads up when you transfer to Dauntless you can choose a new name.Which I think is pretty cool.
The problem is when you chose a new faction you have to go through initiation. If you fail initiation you become factionless. Factionless don't belong in a faction because they got kicked out of their new one. Being factionless is a lot like being divergent, mostly because they don't belong in a faction.
Beatrice, also know as tris, is divergent only she and the person her did the altitude test on her know. If a leader of a faction finds out that their divergent they're a goner. Being divergent is dangerous. Well, that's all I have to say for now.
