Outside, the city is changing. While we have been talking of God's laws and seacrets of the earth, a cold fog has come rolling off the sea, pushing through the allys, sliding over the water, rubbing up agienst the cold stone. As I walk the street falls away behind me, the shop's blue awning lost within seconds. People move like ghosts, their voices disconnected from their bodies; as fast as they loom up they dissapear agien. The fog is so dense that by the time I have crossed toward the Merceria, I can barely see the ground under my feet or tell if the gloom is weather of the beginning of dusk.
