Reality in a dream

Exploration Stage: Garden of Oblivion
From: Lawrence de Bertrand
Description: There used to be outdoor concerts held in the garden, but the melody does not come from the concert hall. Do you see that gazebo over there too?
Completed: I thought I was hallucinating...there were no gazebos here! Does the fog in the city sometimes move buildings? If so, that makes sense. Because it looks like the gazebo is covered with fog.
