Foggy Perspective

From: Conductor
Description: I haven’t given up trying to break out of the City. But I’m no longer doing stupid things like I did on my first day here. I just ran along the rails away from the Station. See? They lead into the fog.\n I’ll show you how this route ends. Just bring me some artifacts.
Completed: During my time spent in the City, I learned a thing or two about how to use its magic. Look, in the circle of artifacts a ghostly object has appeared. This is the "railway knot," I came across it when I was wandering along the rails in the fog. It’s a vicious circle, you see? You can’t get out of it.
