Between the stones grass had grown up, and in places trees had attained a great height.

Palms grew and flourished upon the roofs of many of the buildings, and everywhere clinging vines bedecked the ruins.

It was a wonderful sight, and one which our adventurers never forgot.

Now nothing remained of them but a few crumbling palaces.
