FrobozzCo International was a vast conglomerate of thousands upon thousands of companies that had once held a monopoly over every magical scroll, spell, staff, or magical device of any kind that was produced within the borders of the realms of Quendor until its destruction in the Great Diffusion of 1247 GUE. It can trace its origin to the Frobozz Magic Cave Company, which was formed at the behest of King Duncanthrax. There seem to be some contradictory elements on the history of the formation of the Frobozz Magic Construction Company (the forerunner of the modern industrial giant FrobozzCo International).
