"'Then, looping the loose end of his silk rope about Natala's hips, and cautioning her to hold on with both hands, he lifted her through the window and lowered her the thirty-odd feet to the earth.'"

The mechanics of creating such a machine - involving counter-weights, pulleys and other fine details - are considered sorcery by the ignorant and wisdom by the enlightened.

The practical benefits of such a machine cannot be denied, but civilized peoples who grow too reliant upon them will find that a climbing horde of barbarians can be just as effective, and infinitely more deadly.
