Civil war within the Confederated Nations threatens to engulf the world of Rhun. The Outcast Nations wait impatiently for their chance to strike back at the countries that have enforced their exile for so many years. Heroes versed in the magical power of Runes stand against the tide of chaos. For not only is their knowledge of magic great, they can use it to bring Stryders to life. These towering war machines come in many shapes and sizes, some forged from steel, others carved from stone, and still others grown from living plants and giant insects. All are mighty in their own right, highly prized and jealously guarded by their pilots, crews, and patrons. This is a complete roleplaying game including all the rules needed to create characters, resolve conflicts, cast Runes, and use and design Stryders. (Classic Revised Edition)
