Faction fundamentals

An active faction is a progression system as much as a social group.

  • Faction helps shorten construction and investment timers.
  • Raids, reinforcements, gifts, and faction investments reward coordinated activity.
  • Share rally expectations and event assignments before the timer begins.
  • Keep city rules and non-aggression agreements visible to newer players.
