The Known World The Known World has cultures and a level of technological development that resemble Europe around the 15th century, but without gunpowder. Nations of the known world display a great range of government types. Some nations are populated entirely by demihumans and/or humanoids. By common convention, the boundaries of the "Known World" are those covered in the world map as originally published in the module X1, The Isle of Dread, plus Norwold, the Isle of Dawn, and (pre Wrath of the Immortals) Alphatia. As the name implies, the "Known World" covers the most notable nations of Mystara, the ones most commonly used in Mystara-based campaigns and featured in fiction. It includes the Thyatian Empire, which could be compared to Byzantine Empire; the Grand Duchy of Karameikos (which includes the town of Threshold, the default setting of many classic D&D adventures), comparable to medieval southeastern Europe; the Principalities of Glantri, which is similar to medieval western Europe, ruled by wizard-princes; the Ethengar Khanate, a Mongol-like society; the merchant-run Republic of Darokin, which is based somewhat loosely on the mercantile states of Medieval Italy; the Emirates of Ylaruam which have an Arabic flavor; the Heldannic Territories, ruled by an order of religious Knights devoted to the Immortal Vanya, similar to the Teutonic Knights; the Atruaghin Clans, which have an Amerindian feel; the nation of Sind, based on India during the rule of the Mughals; the Northern Reaches Kingdoms of Ostland, Vestland, the Soderfjord Jarldoms, based on Scandinavian kingdoms at various periods of history; the Dwarven nation of Rockhome; the elven Kingdom of Alfheim; the Halfling lands of the Five Shires; and the Alphatian Empire, ruled by wizards and other spellcasters. To the distant Northwest of the "Known World", across the Great Waste, lies the mysterious lands of Hule, ruled by Hosadus, also known as "The Master". Also on the periphery of the Known World are the Kingdoms of Wendar and Denagoth, the first an elven-dominated nation and the latter a mountainous and dark realm of evil, with ill-intentions towards Wendar. The Adri Varma lies between Sind, Wendar, the Great Waste, and The Black Mountains, forming the northern border of Glantri and defining the northwestern limits of the region. The Savage Coast Mystara includes the Savage Coast, a coastal area located in the south central part of the Brun continent, to the south and west of Hule. The area is a
