The Collective Base

You've learned that the Collective built a hideout deep within one of the cave networks in Draullir.

Acquisition
Go through the door deep inside the cave in the mission The Baryte Rush. The conversation with Lynx starts the mission.

Speak to Crux
She is the leader of the base and has a problem with someone who is faking the Charlatan's orders - giving bad intel. It has already got two recruits killed. She asks Ryder for help to subtly find out who is guilty one. It's one of the people in the base. When the conversation is over, the mission completes and the follow-up mission The Charlatan's Charlatan starts.

Reward
270 xp.
