Beyond the factions (Divergent fan fiction)

What happened after Tris and Tobias weren't around anymore? Factions are rebuilt but not the same. Leaders from each factions so no favorites right? But divergents are these leaders. Soon a group of people will have to save our city because not every candor is honest, not every Dauntless is cruel, not every abnegation is selfless, and not every Erudite is wise.
