Speak to Derc in the Tartarus nightclub in the Kadara Slums. He sits in the corner on the bottom floor marked with a .
Speaking to Derc, Derc asks if Ryder wants to make some easy credits. A surveyor that he sent out hasn't returned and Derc wants to know what happened. Note: No credits are given as a reward despite what Derc states during the conversation.
Travel to the surveyor's last known location in Draullir Edit
The navpointleads to a big cave system in the Draullir region. Someone has set up floodlights powered by generators - too much for one surveyor to carry. There are three datapads, a number of mineral nodes, and multiple lootable containers located throughout the cave system. Note: This does not include The Collective Base portion of the cave explored during The Charlatan's Charlatan.
This datapad is located near the corpse high up on a column of rock on a small wooden shelf with a Titanium mineral node next to the datapad.
Scan surveyor's corpse Edit
Note: The mission The Collective Base can be started in this same cave system before going back to Derc. Exploring the cave further, you come upon a door. Opening it, an asari named Lynx says the Charlatan wants Ryder alive. So this is who set up those floodlights.
Return to Derc Edit
Ryder reports what happened and gives the baryte samples data to Derc.
