Radovid's Realms was nomenclature used both for the forced personal union between the kingdoms of Redania and Temeria,[1][2] later also Kaedwen (after Winter War), and for the Northern Kingdoms during the Third Northern War (because Radovid V was the last powerful-enough king). The term derives from the name of the leader of this union, King Radovid V the Stern of Redania.[2]
