Saskia's Free State is a state in Upper Aedirn created by Saskia. Theoretically, it is a country without prejudice. Being tolerant of all nations and races, elves, humans, mages, and even trolls could live side by side, as was Saskia's vision.
However, the Lodge had different plans for the Free State and planned to take over the country and use it for their own purposes. The leaders of this nation were to become Philippa Eilhart and Sheala de Tancarville. If Geralt lifts the spell from Saskia, she would probably regain power in her country. It is bordered by the Blue Mountains to the east, the Dyfne river to the south and west, and the Pontar to the north.
After the events of the summit at Loc Muinne, Nilfgaard defeats Vergen, their defiant city is razed to the ground and Saskia, with Geralt's help, flees the city after the death of Barclay Els. After losing the battle with the Nilfgaardians, the territory is merged with the province Aedirn.
In 1273, after the end of the Third Northern War, depending on choices made by Geralt in The Witcher 3: Wild Hunt, Saskia's Free State may remain under Imperial occupation, be conquered by Radovid V, or unite with Redania under the leadership of Chancellor Sigismund.
