For the People Quest Walkthrough
This quest starts: After talking to Kleon when you finish the Welcome to Athens quest.
Description: Attika is occupied and Kleon asks you to break the Spartan assault. This is a long and difficult quest in which you have to enter Spartan war camps, destroy their supplies and kill their Polemarchs.
You can light the supplies with the torch. When it comes to Polemarchs, it is best to attack them by surprise to weaken them significantly. After you weaken the enemy enough, return to Kleon and accept the reward: 6000 XP.
