You're in a control room in Airport of the Height. Floating groups of small, indigo lights dance about and the sound of machinery comes from everywhere.
You're outside a museum in The Exchange of the Matters. Heavy hail falls with a regular burst of wind and a half buried pile of terracotta bricks is nearby.
You're in a conference room in The Airport of Tomorrow. Loosely scattered maroon coloured rocks are floating in place and everything has an indigo tint to it.
