Hello, you commented on one of my books so I'm here to explain!
In the world of Divergent people are separated into factions upon birth but can transfer if they wish at the age of 16 here are the factions and what they represent or value
Dauntless: bravery
Abegenation: selflessness
Erudite: knowledge
Candor: Truth
Amity: Peace/Kindness
Hope that helps!
