Atlach-Nacha first appeared in the story The Seven Geases (Clark Ashton Smith, 1934).

Atlach-Nacha is a Great Old One which appears as a huge spider with an anthropoid head. Atlach-Nacha was said to have come to Earth from Saturn along with Tsathoggua; in other version of the myth, the spider god spun a web between the two planets that allowed Tsathoggua to arrive.

The spider-god lives within a great chasm beneath Mount Voormithadreth in Hyperborea, though reports of the god have also come from Siberia and Peru. Atlach-Nacha spends all its time bridging a bottomless chasm between the waking world and the Dreamlands with its web, a task which will keep it occupied until the end of the world.[2]
