Free Slopes began as an anti-Nilfgaard movement in the vicinity of Belhaven. Its original goal was to liberate the Slopes from Nilfgaardian rule, but blossomed into an armed group, wanting all of Sodden liberated.
Members of the movement inadvertently helped Geralt, Cahir and Angoulême, when the trio was surrounded at the Rialto quarry by the Nightingale gang in cooperation with some Nilfgaardian troops.
