You're in a library in Castle of the Flies. Pipes along the ceiling leak a yellow coloured liquid and the hue of everything slowly cycles through the spectrum.
You're in a vault in Acropolis of the Polentas. The hue of everything slowly cycles through the spectrum and collections of big, ivory crystals are growing everywhere.
You're outside a restaurant in Quarter of the Someplace. Boat traffic gently floats through canals of vermillion coloured water and big piles of boxes are scattered about.
