All known Thief languages and dialects both common and dead.
English is the main language spoken in The City, and is stratified into distinct dialects. The Hammerites and Mechanists speak in a sort of Old English, similar to the style of speech seen in King James Version Bibles. Pagans speak in a fractured pidgin. Modern English is spoken through all citizen classes. Commoners and guards speak with American or British Cockney accents, or Poshed American or British accents for the upper class. Even stereotypical "pirate" slang is used by sailors and fishermen.
