The allied army of Caladan Brood and renegade Malazan High Fist Dujek Onearm passed through the Catlin Plain during the Pannion War on their way from Pale to Capustan. It was there that Brood lost his temper with Kruppe and brought down his hammer creating a new range of basaltic mountains.
It was unclear whether the Catlin Plain and the Vision Plain were two names for the same geographical location or were two separate adjoining areas. Neither are marked on the published maps of Genabackis. Saltoan on the Catlin River was said to be on the Vision Plain. The Malazan army passed through the Catlin Plain somewhere between Pale and Capustan north of the Catlin River.
