Osiris Campaign Mission Howling Skies Part 3.
This mission requires the Prospector to visit Base Camp near Gate C, and collect the Auditory Organ item.

Description
Appears to be the organ the howling beasts use to echolocate targets. You're unsure why this was in one of its nests... perhaps molting? Or part of a grim mating ritual?
Story
In Howling Skies Part 1-3, the Prospector is investigating the possibility of the Howler returning to Fortuna III. In part 3, conclusive evidence is found that it is back in the form of the Auditory Organ at Base Camp.
