The master is the standardized set of core programs necessary to create and manage adventurers in Eamon. Normally occupying a single diskette, the master always includes a Main Hall and associated player-management programs and data files; it also commonly contains the first Eamon adventure, The Beginners Cave, and may include certain utilities and documentation. Donald Brown created the first master in or around 1979; improvements and enhancements have since been introduced in subsequent versions, as well as in separate masters created by other developers.
