The Deep-Ones are a race of undersea dwelling humanoids that can surface for weeks at a time. They worship, the undersea Gods, Dagon and Cthulhu and inhabit the underwater city Y'ha-nthlei.
They convert humans into Deep-Ones by "Sexual-Spore Spawning" perpetrated against the young. The transformation usually occurs when the individual reaches middle age. As the hybrid gets older, he or she begins to take on more and more attributes of the Deep-One race: The ears shrink, the eyes bulge and become unblinking, the head narrows and gradually goes bald, the skin becomes scabrous as it changes into scales, and the neck develops folds which later become gills. When the hybrid becomes too obviously non-human, it is hidden away from outsiders.
People who are unfortunate enough to travel in the area where the Deep-Ones frequent are usually eaten alive and remaining body parts used as fertilizer for the Deep-One Kelp Forests.
Those who live near the oceans of the world are at the greatest risk of attack. I am working tirelessly night and day to engineer a virus or organism that can destroy the Deep-One menace.
We at Dr. Fong's House of Mystery will keep you apprised of the situation as it progresses.
