The Giff Treatise is a collection of trade manuals, history, and buying guides for skyships, voidships, and gunpowder-based cannons and mortars. In 921, the first edition was printed on the world of Marragh; its author was a Giff engineer named Towerfoot. The work has greatly expanded from its initial theories and conjectures, with new editions and authors contributing to reflect advancements in products, metallurgy, chemistry, and theory.
