Guiding Thread

Description: In trying to figure out how you found your way into the City, we’ve intruded into forbidden areas of knowledge. The spirits refuse to answer any more questions, but I want to see this through to the end.\n I will extract the answer from the items found if you bring me some charged artifacts.
Completed: Magical powers, reveal what we are looking for! The artifacts are getting white-hot... Watch out!\n Were you hurt by the explosion? Let’s see what we’ve got. My, this is the Conductor’s Machine, which gives the coordinates of the portal to the City!\n You’re saying... No, that can’t be right - Jacob couldn’t have made it...
