In the depths of Kimberley Antarctic Territory perches the Wulungarra Walled City. More than 30 million people live upon this tiny rock, pressed side by side, knocking knees and elbows. The claustrophobic scents of the sunless city have made of it a Mecca for the cylinder's human driftwood. Refugees of all kinds make their homes here; the war-torn Persians, French, and Inca jostle political refugees from America, Afghanistan, Tibet. How does the fantastic city sustain itself, you ask? Only by trade, which forms the lifeblood of the city's daily bread. If war ever breaks these precious arteries, the city is doomed.
