Emhyr var Emreis

Emhyr var Emreis, Deithwen Addan yn Carn aep Morvudd (In the Elder Speech - the White Flame Dancing on the Graves of his Foes), is the current Emperor of Nilfgaard, King of Cintra, lord of Metinna, Ebbing and Gemmera, sovereign of Nazair and Vicovaro in the novels, tv series, movie, and games. He is publicly favourable to the Elder Race, in stark contrast to the Northern monarchs. As of the Witcher 3, Emhyr has also adopted the title Ruler of the North and South, after his conquest of both Aedirn and Temeria during the Third Northern War.

His rule of Nilfgaard is highly aggressive, similar to his predeccesors, with large expansionist policies. This led to the two wars against the North described in the novels. Emhyr var Emreis is an intelligent and brilliant ruler. He picked his people well and crushed all plots against him. He was ruthless toward traitors and moved towards his goals with determination.

He is the father of Ciri and husband of the late Pavetta, having gone by the alias of Duny before assuming his rightful place as emperor.

He ruled from 1257 when he took the throne from the Usurper until 1290 when he either died of natural causes, abdicating his throne, or by assassination if he loses the Third Nordling War. The throne goes to Morvran Voorhis or Ciri depending on the player's choices in The Witcher 3: Wild Hunt, which means that he ruled for 33 years.
