Motion in the Fog

Exploration Stage: Foggy Backstreet
From: Vera
Description: I feel how scared Lucs is, alone in the fog where the Dark Hunter roams. With the help of the scavengers' devices, we'll determine where my brother is. I heard that someone brought a scavenger's navigator at auction in the Foggy Backstreet. Help me get this device!
Completed: Thank you for persuading the owner to lend us the scavenger's navigator! This device picks up any motino in the fog from a distance. If you take the readings correctly, you can understand the motion of whatever subject the navigator senses, be it a rat, bird, or human.
