first appeared in H.P. Lovecraft's short story "The Temple" as a Dionysian statue. Whether Lovecraft intended the statue to be anything other than the centerpiece of a piece of weird fiction is debatable. In 2004, Chaosium released an expanded bestiary to the Mythos which included the entity of Gloon, attributing some non-canonical eldritch and limacine attributes to the entity, a counterpoint to its outwardly pleasing and homoerotic aesthetic. Author Molly Tanzer's novelette "The Infernal History of the Ivybridge Twins" expanded upon Gloon's cult and mythology.

Eiehort - lives within a network of tunnels deep beneath the Severn Valley, in England. It appears as a "bloated blanched oval, supported on a myriad of fleshless legs" with eyes continuously forming in its gelatinous body. When it captures a human, it offers the captive a "bargain". If the captive refuses, Eihort rams the victim violently to death. If the captive accepts the offer, the horror implants its immature "brood" inside the victim's body. The brood will eventually mature, and kill their host. According to the Revelations of Glaaki, after the fall of humanity, Eihort's brood will be born into light

Cynothoglys - first appeared in Thomas Ligotti's short story "The Prodigy of Dreams" (1994). The being appears as a shapeless, multiform entity with a single arm used for catching those who summoned her, and bringing them a painless, ecstatic death. In ancient times, she once held a small cult in Italy, which paid her homage rather than worshiping her, since actual worship would be the same as summoning the god. They considered her to be no mere Cloacina, but the mortician of all creatures, even the gods themselves

Considered a Great Old One within the pantheon of Lovecraftian cosmic entities, the creature has since been featured in numerous popular culture references. Lovecraft depicts Cthulhu as a gigantic entity worshipped by cultists. Cthulhu's appearance is described as looking like an octopus, a dragon, and a caricature of human form. Its name was given to the Lovecraft-inspired universe where it and its fellow entities existed, the Cthulhu Mythos.

The being came to Earth from the star Fomalhaut, briefly visiting the planet Yaksh (Neptune) before taking up residence in Mount Yarak, a legendary mountain atop the North Pole.

Aphoom-Zhah is believed to be responsible for the glaciation that eventually overwhelmed Hyperborea, Zobna, and Lomar.
