The remains of a vanished civilization. A human--English, Russian, and Chinese-speaking--civilization. Seven vast chambers containing forests, lakes, rivers, hanging cities...And museums describing the Death; the catastrophic war that was about to occur; the horror and the long winter that would follow.
