It all goes back to the first Cloud Strider, a woman named Mikaela Julaha. "We don't know enough, unfortunately. Record-keeping was spotty back then. We were fighting just to survive, so no one was keeping receipts we could sift through centuries later. What I do know from context clues is that the Strider was the first person to use the Occlusion, and the only person who really knew what it is—except maybe the Vex, apparently. All I know for sure is she never set out to be a hero. She just wanted a safe home, where her kids didn't need to fight every day just to survive."

The Shadow Legion have uncovered a Vex tunneling operation, but the comms chatter Quinn has been able to pick up hasn't been very specific apart from that. The Shadow Legion have been ordered away from the operation, but that still leaves many places in Neomuna where the Vex could be working, and the Shadow Legion might yet be in active retreat.

Sweep through the areas where Vex and Shadow Legion are fighting to rule out those areas, and collect encrypted data from them to analyze and further narrow down where the Vex operation could be. With any luck, the chase will help you bond with the Strider's legacy—but the defense of the city is the most vital goal.

Unlock a Terminal Overload Key Chest in each occupied area of Neomuna to begin tracking the Vex tunneling operation.
