Pat Hurst, over the course of his universally highly regarded Eamon adventures, attempted to unify the details of the fictional planet Eamon, providing an coherent story concerning Eamon's geography, politics, and pantheon. The Main Hall, according to Hurst's continuity, lies in the city of Evenhold, on the coast of the Malphigian sea. Beyond his four adventures—The Pyramid of Anharos, Buccaneer!, Grunewalde, and The Dark Brotherhood—Hurst's ideas informed Mike Ellis' Well of the Great Ones (as well as A Runcible Cargo). Hurst's portrait of Eamon was made concrete by a sort of "series bible," the Eamon Gazetteer, mentioned several times in the EAG Newsletter.
Huw Williams—super sleuth that he is—was able to not only track down Pat Hurst, but also coaxed him into scanning a copy of the fabled Gazetteer, a copy of which may be found at www.eamononline.com. Both scanned and transcribed versions are posted. It's a very entertaining read and a very rich component of Eamon history, so make sure to check it out.
