Prerequisites:
Starting in Prodromos, Eos Outpost, examine the terminal near the merchant, eastern shelter and read the only email there to start this task. For the next step, you have to return to the Nexus.
When you're in the Nexus and after learning about the AVP perks, make this task active and talk to Brecka. After asking to wake up Darket Tiervian from Cryo, you have to return to Prodromos again.
Back in Prodromos again, talk to Darket in Prodromos to update this task. You’ll then have to find two Kett caches in the Phytheus System, the same system where Eos is located. Leave the planet and use the scanner to spot two anomalies in the outer reaches of the system. Send probes on these two anomalies to find the Kett Orbital Caches and loot them. Task complete.
