The Sousalax is a deep, bass instrument. It is considered to be the largest of all lung-driven instruments. A total of six or seven men along the western coast of Lyrian had the only lungs large enough to play the sousalax, one of these men being Tark.
The sousalax is used either in the Northern Hinterlands or north of the Hinterlands to summon walruses and sea elephants.
