From publisher blurb:
Rope may be the most important invention of all time. It is strong, yet flexible. It built ancient monuments and powered the sailing ships that began global commerce. Rope is also a staple of fantasy role playing games, whether climbing ice cliffs, tying up prisoners, or keeping the party from getting separated in a blizzard.
