Body Language takes place in Lydia—a kingdom in Asia Minor (now part of modern Turkey) that was conquered by Cyrus the Great during the 6th century BC and became part of the Persian Empire.
Years later, Lykos, the son of the king of the Thracian city-state, Aenus, is travelling incognito through the conquered province.
