Galach from Dune

[vegfarandi]

Does anyone have any leads on any kind of information or material on Galach or other conlangs made for the latest Dune movies?

[Vilike]

David and Jessie Peterson created conlangs for the movies: Chakobsa (and its orthography) the language of the Fremen, and the secret handsigns used by Paul and Jessica (and maybe also the sign language used by a Harkonnen pilot?). Sardaukar is only a phonology; and there are no Galach or "Harkonnen" conlangs: the characters you see onscreen to transcribe the former are a creation of the design department (so, gibberish) and the dialogue for the latter you can hear at the beginning of Part II is scrambled English audio (so, gibberish).

You can learn more about those conlangs at the Peterson's wiki and the dumping folder at David's website.
