Viroleda (in The Witcher computer game: Viroledo) is a city in Nilfgaard known for its swordsmen who developed a particular style of sword fighting called Viroledan Naev'de Feaine Glaeddyv used when facing multiple opponents. Viroledan masters of this style were said to be able to fight nine opponents simultaneously.
In Season of Storms, Geralt received a fake Viroledan sword from Dandelion, though the poet did not realize it was a fake. Pinety had a real sword from Viroledo, which he later gave to Geralt.
In The Tower of the Swallow, Esterhazy proposes a light Viroledan-style sword for Ciri.
