Asshai and the Shadow Lands are mysterious locations in the "Ice and Fire" world. They are first mentioned in "A Game of Thrones" and were first mapped in "The Lands of Ice and Fire", lying on the far east of the known world. Martin is unsure if the books will ever take the readers to Asshai, but said that readers may learn more through the POV character Melisandre (who originates from Asshai) or through the memories and mentions of other characters. Jorah Mormont describes Asshai as a port city far to the south of the Dothraki sea, at the end of the known world. Asshai exports such goods as black amethysts, amber and dragonglass. At another time, Jorah Mormont tells Daenerys of great kingdoms to the east of the Red Waste, and lists Asshai by the Shadow as one of the cities full of wonders there. According to Martin, all ship travels between Westeros and Asshai go via the Summer Sea and the Jade Sea through the straits at Qarth, and that the common folk still believe the world to be flat. However, according to Martin, "Asshai is not nearly important to trade as Yi Ti, and the rich port cities of Yi Ti (and Leng) and more easily reached via Qarth." Quaithe of the Shadow prophesies Daenerys in Qarth that "To go north, you must journey south. To reach the west, you must go east [...] and to touch the light you must pass beneath the shadow." When Daenerys interprets this to mean she must go to Asshai, Quaithe says she would find the truth there.
