The console has been hastily, but cleverly, rigged for communications. When you approach, it flickers to life.
Micah-10 tells you about her mission to find and save unpartnered Ghosts. They returned to help the Traveler as soon as they could, but the Witness's infection caused chaos. They need help.
The console's interface shows an area of the Pale Heart that Micah has marked. She says she's receiving telemetry from a Ghost in the area, but it must be damaged; the signal is unclear. You'll need to search to find it.
She also says that some of the Ghosts have helped scout safe zones within the Pale Heart. You should be able to use them as LZs to travel more efficiently.
