History
Myths and Legends
Magnum Innominandum was known to H.P. Lovecraft during a Roman dream he recalled in three letters, one of those being incorporated in "The Horror from the Hills" and one posthumously published as HPL: "The Very Old Folk". It was also mentioned in HPL: "the Whisperer in Darkness" alongside many mythos concepts such as Hastur, the Yellow Sign or Yog-Sothoth. It also is part of an incarnation from De Vermis Mysteriis penned by Lovecraft for CIRCLE: "The Shambler from the Stars"
Lovecraft mentioned the Nameless Mist in a family tree of Azathoth. The Nameless Mist was given the name "Nyog'Sothep" and "N'yog-Sothep" by later authors. The Magnum Innominandum and The Nameless Mist were finally unified as the same entity later on.
