Arcadia

Changelings say that their home country is a place called Arcadia, a now unreachable place of pure dream. Faeries, they assert, are the dreams of humanity made manifest, and Arcadia is the heart of those dreams. The facts, however, are difficult to determine (a) because changelings, by definition, are not "true" faeries, but a sort of faerie/human hybrid adapted to dealing with the mortal world and (b) because Arcadia itself has been impossible to reach or even detect for a very long time (fae scholars mark the Black Plague as the first moments of the Shattering, the process by which Arcadia broke away from Earth's Dreaming).
