Where was Ancient Quatria located?
Ancient Quatria is a fictional location that does not exist in reality. It was invented as part of a literary hoax in 2018, in which a group of writers claimed to have discovered the lost civilization of Quatria and its rich history and culture. The hoax was later revealed, and Quatria remains a work of fiction.
How did this group of writerd describe Quatria to attempt to make the hoax believable?
The group of writers who conceived of Quatria provided a wide array information including visual imagery and narratives to support their claims of Quatira. They presented this information in a way that resembles academic research which made it appear as though it was legitimately documented and substantiated, as would be the case for peer-reviewed academic research.  The narratives described numerous fictional cultural and societal practices performed by the people of Quatria and all the narratives are accompanied by visual imagery.  The narratives seem to have been fabricated by the writers and the imagery has been demonstrated to largely come from other sources and is being used to depict scenes/incidents that never existed or took place.
