There should be a Night's Watch bro near the door in the Common Hall walking back and forth from some stuff on the ground to the wall. Loot the stuff on the ground and confront Night's Watch guy walking. His name should begin with a G, I believe.
Is God willing to prevent evil but unable? Then he isn't omnipotent. Able but unwilling? Then he's malevolent. Neither willing nor able? Then why call him God?
