The Whisperer in Darkness
Smith wrote most of his weird fiction and Cthulhu Mythos stories, partially inspired by H. P. Lovecraft. Creatures of his invention include Aforgomon, Rlim-Shaikorth, Mordiggian, Tsathoggua, the wizard Eibon, and various others. In an homage to his friend, Lovecraft referred in "The Whisperer in Darkness" and "The Battle That Ended the Century" (written in collaboration with R. H. Barlow) to an Atlantean high-priest, "Klarkash-Ton".
