Knygathin Zhaum is a creature created by the late American author Clark Ashton Smith.
Overview
The child of Sfatlicllp and a Voormi, Knygathin Zhaum repopulated Hyperborea after humankind deserted the city of Commoriom. Athammaus attempted to execute it by beheading, but because of its preternatural heritage, such attempts proved unsuccessful and only served to aggravate it. As a descendant of Cxaxukluth, Knygathin Zhaum reproduced by fission and thus created an Azathothian strain among the Hyperborean Voormi.
