The Thunder River served as the border between Aquilonia and the Pictish Wilderness as it flowed from Cimmeria past Gunderland and separated Westermarck of the Bossonian Marches from Conajohara, before passing through Zingara and Argos where it emptied into the Western Ocean.
On their way to Cascan, Conan, Delmurio, and Tetra were attacked by a bunch of fishermen who had resorted to banditry because of the civil war in Zingara. After defeating them, they reached the fishing village and sailed downriver to Argos.
