Sylantia is located some six thousand miles to the west of the famous City of Fernwall, the undisputed commercial capitol of the world. Its northern tip extends just beyond 50° North Latitude and the southern tip just below to 10° N. Latitude, making the continent over 2,400 nautical miles (4,445 kilometers) in length.
Most of the water on the continent comes from high in the Kaŝeruk Range and runs south, into the fertile plains of Vin-Llamáz and Surmeidän. Both the wild lands north of the Kaŝeruk Range and the the Kingdom of Vin-Nôrë are fairly arid lands. Most of Vin-Nôrë is really little more than the eastern slope of the Kaŝeruk. The land is naturally dry and arid. The soil is rocky and rich with minerals an nutrients, but very few rivers and streams run eastward out of the mountains.
The Kaŝeruk Range itself is one of the planets natural, but now dead, super volcanoes and is riddled with empty magma chambers and tunnels that are now full of millions of years of rain water that spills out of high mountain lakes and underground aquifers into rivers and streams on the surface and, far beneath the surface, also supply the dwarves with water.
