|Side Quest: Free the Slaves|
|Kill all of the Khans.|
|Speak to the slaves.|
|Reward: 200-400 XP|
To complete this quest, the Vault Dweller has to kill all of the Khans at the Khan Base. If he manages to do so and either of the two slaves survive, the Vault Dweller must then talk to them to complete the quest.
This quest is essentially the opposite of the quest Join the Khans. Instead of receiving an XP reward for freeing the slaves, the Vault Dweller will receive the XP reward for killing them.
