Fast Elevator Horizontal

Description
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 horde of barbarians following a rope hand over hand can be just as effective, and infinitely more deadly.
