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.
