Tobias Eaton grows up in the Abnegation faction under the rule of his father, Marcus, who is known for his strength and violence. The constant fear and oppression drive him to leave Abnegation at the Choosing Ceremony and join the Dauntless Ones. There, he calls himself Four because he has only four major fears—unusual even among the Brave Ones. As an instructor, he outwardly displays strength and discipline, but recognizes the faction's problems: brutality, abuse of power, and the increasing militarization under Jeanine Matthews. Four himself is Divergent and can manipulate simulations, but he keeps his true nature hidden because Divergence is considered a threat. The day is called the Choosing Ceremony. On this day in Divergent, teenagers decide which faction they want to belong to based on their tests and personal preferences. And you are one of the Abnegation, have chosen to be one of the Dauntless Ones.
