You walk down the hallway.
You look around and see pictures on the wall.
In one of the pictures you see the man who opened the door with his arm around THE WIZARD
You are now even more determined to find the man to ask him how to get to the Wizard.
Keep walking.
You hear a thump.
You run down the stairs to find the man in the foyer. "Where did you go? you ask the man. He explains how he ran out to do a errand and forgot that the door locks from the outside.
Not sure if that is making any sense, you take a chance and ask the man how to get to the Wizard.
The man tells you that he is going to meet his old friend the Wizard on his way to the outside world.
