Chakobsa, also known as the magnetic language, was a hybrid language derived from various ancient Bhotani dialects, especially the Bhotani hunting language.
The language probably came into being after the first few Wars of Assassins. It became used to a lesser or greater extent by several groups, including the Bene Gesserit and the Fremen.
When House Corrino ruled the known universe, House Atreides used a form of Chakobsa as their Battle Language.
