Radovid III of Redania, also known as "the Bold" or "the Red" (for his hair colour), was the great-grandson of Radovid the Great and the king of Redania. He married princess Viviana of Lyria. Viviana had one son, Vridank, presumably also Radovid's son.

Determined to regain the prestige accorded to his great grandfather, he tried to assert Redanian sovereignty over the North. These attempts were soundly rejected by the Northern rulers and lead to the first treaty negotiations. During his reign, border scuffles with Aedirn broke out and customs wars were waged with Kaedwen, Kovir, and Temeria. He and Benda of Kaedwen travelled to the winter capital of Kovir, Lan Exeter, to enter negotiations with Gedovius. By virtue of the First Treaty of Lan Exeter, he was allowed to retain the title of King of Kovir and Poviss, but only until his death.

I have nothing against witchers. Let them hunt vampires. As long as they pay taxes.
