Barbas is a servant of Clavicus Vile who usually takes the form of a talking dog. He can be found inside Willowgrove Cavern in Reaper's March. He also sometimes works as a merchant in the form of a scamp, under the name Creeper.
The Vestige must find a way to enable Pircalmo's ritual. Inside the cavern, Barbas will tell the them to destroy the altar. Doing this will enable Pircarmo's magic but will also free Barbas from his binding to the cavern.[?] [?]
