Exploration Stage: Foggy Backstreet
From: Vera
Description: The scavengers' devices will help me find Lucas in this foggy streets maze. When I determine my brother's location, I'm going after him at once. I'll definitely need a device that scavengers call "the fog's cradle." Help me find it.
Completed: Great, we have the fog's cradle! The principle is quite simple. The oscillation of the balls accelerates in particularly dangerous areas of the fog, warning you that you'd better not go there. I'll take the device with me when I determine where Lucas is, then I'll go after him.
