Hyperborea

Hyperborea was a country on Earth that may have existed at the time of Atlantis. Ashley Chapel was directed to Hyperborean texts by Saraquazel which told him how to transmogrify human beings into demons. Finding the Hyperborean term unpronounceable, Chapel called these things cybrids.

A large thin book in faded beige contained transcriptions of texts from the time of Atlantis, including an inscription in the corrupted form of quantum mnemonics used in the Millennium Codex. Anne Travers leapt to the wrong conclusion when Chapel had removed this book with The Many Eyes, Lies and Lives of Yog-Sothoth from the Library of St John the Beheaded. (PROSE: Millennial Rites)

A model of the Earth in the Museum of Things That Don't Exist depicted Earth with a version of the country based on inaccurate information. (PROSE: The Taking of Planet 5)

Behind the scenes

 * The only Hyperborean text mentioned in Millennial Rites is Clark Ashton Smith's fictional Book of Eibon. Even Eibon himself could barely articulate the name of his patron deity's uncle "Hziulquoigmnzhah".
 * Although Hyperborea is an old concept, the Elder Thing exhibit in The Taking of Planet 5 indicated fringe science took At the Mountains of Madness as real. In that work, H. P. Lovecraft mentioned Hyperborea and Smith's Hyperborean capital cities Commoriom and Uzuldaroum.
