The air was warm, moist, like the air inside a house-tree. The very city was alive, growing.Windows in the roof let in some light, while glowing gems overhead provided the rest. As Gallen moved deeper into this living catacomb, he twice came upon open-air bazaars where merchants in colorful swirling robes sought to sell him fabulous merchandise: a pair of living lungs that could attach to his back and let him breathe underwater; the seeds to a flower that could be planted one day, grow six feet overnight, and break into glorious blooms; a hood that would let him talk to a dead man; a tiny plug that he could place in his ear so that he could always listen to music; a cream that not only removed wrinkles and blemishes from skin but also left the wearer pleasantly scented for a number of years.Gallen recognized that much of it was junk and gadgetry, trifles for a people who had everything. But still vendors hawked their wares, trying to engage his attention in odd ways. At one shop, a beautiful woman appeared out of thin air.
