Map of Nepheron.


To explore the Columbia system you’ll first need to complete the assignment UNC: Cerberus, which will require you to travel to Binthu in the Yangtze system.

The main event on Nepheron is an Underground Facility south-of-center on the map, which is where the assignment UNC: Hades’ Dogs will take place. Aside from that, you’ll find a Thresher Maw in the southwestern corner of the map, just west of the aforementioned facility.
