Interlacing of City Veins

Exploration Stage: South Fort
From: Lucas Light
Description: Our living City is helping us find the artifact that the Wanderer is supposed to protect. We found a number that might lead to a house or street. We could use a hint to find out what it is. Maybe the City will give us another map if we look around.
Completed: You found a bizarre map on a keychain? Oh, I saw one when Agent Kira came to see my sister. But Kira never loses things, so it must be a replica of the keychain sent to me by the City. There’s a street shown here! I think that’s where we should look for the house with the number we need!
