World

The Witcher series take place on an unnamed planet referred to by its people as the World, the Earth or the Globe. Approximately 90% of land is on the northern hemisphere.

Astronomic characteristics
The globe orbits a star referred to by its inhabitants as the Sun or Feainn. It has one moon. Unlike on Earth, each month begins at the new moon, and the full moon can last a couple of nights, usually around the 17th. Months April and August have 30 days.

The orbit is eliptic. Due to its (cyclical) instability and disproportion between landmasses in both hemispheres it is believed that about 3.000 years after the life of Nimue verch Wledyr ap Gwyn most of the north will enter the Ice Age, believed to be the White Frost from Ithlinne's Prophecy.

Southern Hemisphere
The southern hemisphere is mainly covered by vast ocean. During the nothern hemisphere's winter the hot air masses from the southern hemisphere flow along the sea currents to the north, where they condensate and subsequently freeze, causing snowfall. It is not much known about the lands located there.

Northern Hemisphere
The northern hemisphere have much more land than the southern one. The most known is known as the Continent, and comprises of Northern and Eastern Realms, the Nilfgaardian Empire and Far North. Adjacent to it from the west are Skellige Isles and from the south lands of Barsa, Hannu, Ofir and Zangvebar. West to the Continent, across the Great Sea, lies the western continent discovered by Fabio Sachs; its eastern part is known as Eastern Coast.
