The Northern Kingdoms or the Northern Realms , sometimes just referred to as the Four Kingdoms, are a group of human states north of the Amell mountains. Their inhabitants are called Nordlings by the Nilfgaardians (both the ones from the core of the Empire, and from the conquered provinces). Aside from humans, a number of dwarves, elves, gnomes, and halflings live in the Northern Kingdoms as second-class citizens.
The Northern Kingdoms were invaded and partially conquered by the Nilfgaardian Empire.
During the Third Northern War, only King Radovid V of Redania remained of all the crowned heads of the major kingdoms. For this reason, during this war the Northern Kingdoms were known as Radovid's Realms.
