Midkemia is a fictional world created by a fantasy role-playing group and popularized by Raymond E. Feist where most of the Riftwar books take place. Only the Empire Trilogy, which was co-written with Janny Wurts, takes place entirely on Kelewan, another world connected to Midkemia by magically created rifts in space.
Midkemia is very similar to Earth in climate, and its flora and fauna. It has three continents: Triagia, Novindus and Wiñet. It has two oceans, though there are various names for them depending on the continent or nation. The Endless Sea is west of Triagia and is east of Novindus where it is called the Blue Sea. The Sea of Tears is east of Triagia and west of Novindus where it is called the Green Sea.
Triagia is the largest continent on Midkemia. Humans constitute the vast majority of the population of this continent, with other races contributing almost negligibly to the total. The extreme north is mostly sparsely inhabited wilderness with few enduring settlements. The continent surrounds, but does not completely enclose, two large seas, the Bitter Sea to the west and the Sea of Kingdoms to the east, which together form a moderately-sized isthmus in the middle of Triaga located about one-third of the length of the continent from south to north. The northern portion is heavily forested, but the south has few forests and is described in ways that would suggest a more equatorial latitude. The Jal-Pur desert is the most notable desert on the continent and occupies most of the central expanse of the southern landmass. The two largest nations on this continent are, from south to north, the Empire of Great Kesh and the Kingdom of the Isles.
The northern parts of Triagia seem to be based on European culture - for example, Bas-Tyra is based on France, and Rodez on Spain - while the south is based on Africa and the Middle East - for example, the women of the Jal-Pur desert in Kesh wear head coverings similar to the hijab worn by women in Islamic cultures.
The vast majority of Feist's work which feature Midkemia occur at least in part on Triagia, and most take place there in their entirety.
Novindus is the second largest continent on Midkemia with a variety of landscapes. It is to the west of the Triagia across the Endless Sea and to the east across the Sea of Tears, and it is not immediately clear from the literature which is the closer distance, suggesting that it is probably close to halfway around the globe in either direction. Politically, it has a collection of largely independent city-states which are spread out across the continent but form no overarching political system.
