The entire civilization of the Fifth Kingdom had been placed directly upon the Fourth, which had been leveled to the ground by invaders. The Fourth had been built directly over the Third, which had been demolished by fire (and shoddy wood construction). The ruins of the Second, destroyed by the war with the dragons lay beneath the Third. The First Kingdom was somewhere beneath that. It had not been destroyed, it had simply faded away. Beneath all of these cities, stacked like blocks, was the earth, which would remain, after the specks of cities had been washed from her skin.
