Prerequisite: Available as soon as you reach Techiix.
Find a historian named Rjoek who’s hanging around behind some angaran cruisers in the southern cavern of Techiix. He’ll ask you to help his colleagues who were trapped while trying to recover a priceless angaran artifact in Eroesk Ruins.
The ruins’ location will be marked in the map. On your way there, make sure to activate the forward station if you haven’t done so yet. Enter the icy tunnel to reach the ruins. There are a couple of hostiles waiting for you there so make sure you come in with Weapons hot.
After eliminating the kett, talk to the turian named Astra. Just approach him and the objective will activate automatically. More kett reinforcements will arrive. Eliminate them then finally talk to Astra to update your objective.
You need to bring the map back to the Resistance. However, you’ll have the optional task of going back to Techiix to confront Rjoek for lying to you about the map. If you have Jaal in your party, he will convince Rjoek to report back to the Resistance instead.
Either way, you have to deliver the map to Intelligence Officer Kaas in the main operations room of the Resistance HQ to complete this mission.
